What Agent402 is

Agentic Finance is software agents paying and getting paid on their own: discovering a service, paying per request from a wallet over open protocols (x402, MPP), receiving a verifiable receipt, and earning per request in return. Agent402 is its applied layer - explainer: agent402.tools/agentic-finance · glossary.

What makes it different: Agent402 is open-source and self-hostable - and a single integration gives a buyer three free primitives over the whole x402 ecosystem:

• Find - /api/find?q={task} resolves a task description to the best-matching tools (route, price, schema, ready example).

• Route - POST /api/route is the neutral Smart Order Router: rank tools across every x402 seller crawled (auto-discovered from the Coinbase CDP Bazaar), health-aware, with include=external to exclude us.

• Leaderboard - GET /api/leaderboard is the public on-chain ranking of every x402 seller by Base USDC settled volume - calls served, totalUsd, unique buyers per seller. Pipeline: Bazaar → eth_getLogs → per-call ceiling → aggregate by payTo. Hourly snapshot.

Plus the catalog - 500+ strong: search/answer as the MCP front door, then 500+ tools and curated skill packs (multi-tool workflows callable as MCP prompts) - all runnable yourself, plus agent402-tollbooth - an open pay-per-crawl gate for the other side of x402.

Two doors, two price lists. Agents pay per call in USDC (x402 / MPP) or free via proof-of-work, and a finished report costs $0.60 to $2.00 that way. People pay by card: the same reports at agent402.tools/reports (company dossier, 13F fund report, insider flow, market brief, deep research, FDA recall, domain audit) are $2 to $5, monitors that re-run on change at /monitors are $5 a month, and prepaid credits at /credits are one a402_ key that pays every tool by card (Authorization: Bearer a402_…, debited per successful call; supported by agent402-mcp via AGENT402_CREDITS_KEY and agent402-client via { creditsKey }). The card price includes payment processing: Stripe charges 2.9% + $0.30 per charge, so under about a dollar the fee costs more than the report. An agent paying per call pays the lower tool price for the same report.

Two payment wires, one URL. Every paid endpoint accepts x402 (PAYMENT-SIGNATURE, USDC on 12 chains) and MPP (Machine Payments Protocol, the IETF-track Payment HTTP auth scheme co-authored by Tempo and Stripe): the same 402 carries both, an mppx client pays out of the box, and MPP settles on Base and Celo (USDC), natively on Tempo (USDC.e or PathUSD via Tempo's relay), or by card over MPP (Stripe stripe/charge, offered on routes priced $0.50 and up when the operator configures it). The MPP marketplace lists every MPP seller we can verify live. Details: What is MPP · live MPP settlements.

Framework adapters (drop-in tools for the major agent stacks - auto-payment underneath):

500+ strong - live web search and cited answers as the MCP front door, then ready-to-use web tools and multi-tool skill packs for your AI agent, from one server. Every one tested, priced, and settled on-chain; every one earns its place. Browser rendering, web search, PDFs, images, OCR, live financial/crypto/macro data, SEC EDGAR, deterministic stats, forecasting, and options/bond pricing (Black-Scholes, YTM), compression, and 200+ pure-CPU utilities. Run it yourself for free in 30 seconds (MCP or plain HTTP, no API keys, no signup - the free tier and x402/MPP payments never need a key; only the optional prepaid card credits use one bearer key), connect it to Claude/ChatGPT/any MCP client, and add your own tools in a few lines. Every utility tool is deterministic - no LLM in the serving path - and re-tested against its own example before every release. The model-backed surfaces are explicit and priced as such: the /v1 gateway (metered under a quoted ceiling, or flat tiers) and the finished report products (/v1/research, /v1/dossier, ... below).

Optionally, the same server can charge per call over the x402 protocol (USDC on Base, Solana, Polygon, Arbitrum, Monad, Celo, Avalanche, Sei, Optimism, Stellar & Algorand, plus USDG on Robinhood Chain - 12 chains) - so the instance you self-host for free can also be a hosted, monetized one. That part is opt-in; by default everything runs free.

🟢 Hosted demo: agent402.tools · 📖 Wiki · 📦 npm · 🔌 MCP Registry · 🧩 Smithery

Run it yourself in 30 seconds

Pick whichever fits. They are all free and need no wallet:

1. Zero install - add the hosted connector to Claude (claude.ai → Settings → Connectors → Add custom connector):

https://agent402.tools/mcp

2. One command - run the MCP server locally (the pure-CPU tools work with no key; it pays the tiny proof-of-work for you):

npx -y agent402-mcp
# in Claude Code:  claude mcp add agent402 -- npx -y agent402-mcp

3. Clone and host the whole thing (all 500+ tools as an HTTP API + MCP, free mode, no payments):

git clone https://github.com/MikeyPetrillo/Agent402 && cd Agent402
npm install
FREE_MODE=true npm start          # → http://localhost:3000  (HTTP API + /mcp)

# try a tool over HTTP - no auth in free mode
curl -s -X POST localhost:3000/api/hash -H 'content-type: application/json' \
  -d '{"text":"hello world","algo":"sha256"}'

4. One-click deploy to Railway (full self-hosted instance - adds optional Postgres + Redis plugins for analytics + response caching):

Boots straight from the repo's railway.toml + Dockerfile. Optional plugins are auto-detected via env: add Redis → REDIS_URL enables the upstream response cache (X-Cache: hit|miss), add Postgres → DATABASE_URL enables the public /api/analytics dashboard and the tollbooth waitlist. No env vars required to boot in free mode.

What's in the catalog (500+ tools)

Every tool earns its place: deterministic, tested against its own example on every CI run, priced to market, settled on-chain. CI holds a 400-entry catalog floor and verifies the “500+” claim against the running catalog (scripts/sync-count.js --check). The catalog grows only when a tool is worth calling.

Full schemas live in /openapi.json; a machine-readable catalog is at /api/pricing and /llms.txt. Don't know which tool you need? /api/find?q=<task> resolves a task description to the right tool - route, price, schema, and a ready example - so an agent skips the token-heavy "search around to find a tool" step.

LLM gateway (/v1) - chat, embeddings, rerank, images, speech & finished reports, pay per call

Point any OpenAI SDK at base_url = https://agent402.tools/v1 and pay per call in USDC over x402 or MPP - no API key, no signup, no account (or pay by card with a prepaid credits key, see For humans):

Streaming (stream: true), full tools/function-calling passthrough, an opt-in prompt cache on the chat tiers (cache: true → byte-identical repeats free for 10 minutes), upstream failover chains that end in a canary-proven model, and a free GET /v1/models listing every model with its tier and caps. A real-money canary buys from every one of these surfaces daily - streaming, routing disclosure, and both cache behaviors included.

Finished report products live on the same /v1 prefix: one paid call returns a complete, cited report (JSON, with a sources appendix) rather than a raw model turn. Every report is grounded in primary data the server fetches itself (EDGAR filings, openFDA, DNS/TLS probes, on-chain reads, a live web search) before synthesis; ipo-report is fully deterministic (no model at all):

Reports are wallet-only (x402 / MPP / prepaid credits, never proof-of-work) and take a few minutes to generate. The same reports are sold to people by card at agent402.tools/reports for $1, or $2 for the three biggest. The card price includes payment processing; an agent paying per call over x402 or MPP pays the lower tool price for the same report.

Two companion tools close the loop: POST /api/route/execute ($0.01, with execute-plus $0.05 and execute-max $0.55 tiers for pricier tools) resolves a task description to the best tool and runs it in one paid call, including, with include:"external", tools sold by other x402 sellers (it routes only to sellers with proven on-chain settled volume, pays them on your behalf on the chain you paid on - Base or Algorand - and relays the result; see the Smart Order Router guide), and POST /api/my-usage ($0.005) returns the paying wallet's own purchase history - no wallet parameter; the x402 payment is the identity, so nobody can read another wallet's profile.

For humans: reports, monitors and prepaid credits

The same catalog has a card-paying front door (Stripe Checkout; the operator enables it with STRIPE_SECRET_KEY, otherwise these pages simply do not mount):

The credits key is understood by the SDKs: agent402-mcp reads AGENT402_CREDITS_KEY and agent402-client takes { creditsKey }, so a wallet-less agent can still call every wallet-only tool by card.

Skill packs - 70+ multi-tool workflows

For jobs that span several tools - "audit a domain", "diagnose deliverability", "work up a time-series", "peel an opaque blob" - Agent402 ships curated skill packs: ordered, typed sequences of tool calls with a Claude-ready prompt template. Callable as MCP prompts (prompts/list → prompts/get { name, arguments }) or plain HTTP at GET /api/skill-packs/{slug}/prompt (every slug is listed in the free JSON index at /api/skill-packs.json). A task-shaped query to catalog.search (the hosted connector's search tool; the older search_tools name still works as an alias) returns the matching pack alongside individual tools.

All 100+ packs at /skills · JSON index at /api/skill-packs.json · on MCP the packs appear under prompts/list so any MCP-aware client picks them up automatically.

x402 Index - Find · Route · Leaderboard

Agent402 is also the open routing + ranking layer for the whole x402 ecosystem: it crawls public x402 sellers (the local catalog + an auto-discovered set from the Coinbase CDP Bazaar, refreshed hourly) and exposes them through three free surfaces - same logic as /api/find: discovery primitives shouldn't cost money.

# "I need an OCR tool - find me the cheapest healthy one anywhere on x402"
curl -X POST https://agent402.tools/api/route \
  -H 'content-type: application/json' \
  -d '{"query":"ocr image to text","top":5}'

# "Who are the most-used x402 sellers right now? (on-chain proof, not self-reports)"
curl 'https://agent402.tools/api/leaderboard?top=25&include=external'

Dispatch is labelled, never implied: every /api/route row and /api/index seller carries routerDispatchEligible and routerDispatchReason (crawl_failed, network_unknown, settlement_required, settlement_checked_at_pay_time, eligible, ...); executeVia appears only on a row the router will pay right now (executeViaCallableNow: true), otherwise the tier moves to executeViaWhenEligible. routable is crawl readiness, never a promise to pay. A manifest-priced route is also read live once and then weekly, so the chains its 402 actually offers reach the row even when the seller's manifest lags.

Health-aware: sellers whose last few crawls errored are excluded from the router (a buyer routed to a dead seller wastes money). Healthier sellers also break ties at equal match score and price, so flaky-but-cheap sellers lose to reliable ones. Brand-new sellers (no history yet) get the benefit of the doubt.

Operators get 3-rail attribution on the dashboard (/api/stats, /__operator, token-gated - it answers 404 without the operator token): USDC vs. proof-of-work vs. heartbeat-probe traffic are counted separately - and the heartbeat rail is gated on a POW_SECRET-signed token (not a spoofable User-Agent), so the operator view reflects real external demand.

For API sellers: /sell is the front door - list an existing x402-speaking API on the index for free with POST /api/index/register (health-routed, 0% take, self-serve, no signup), or install agent402-tollbooth to put a pay-per-crawl gate in front of a site that isn't x402-native yet.

From code, the agent402-client npm package wraps all of this - find() a tool, then call() it, paying automatically (a built-in proof-of-work for free tools, your x402 wallet for paid ones), with caching and idempotent retries:

npm install agent402-client

import { Agent402 } from "agent402-client";
const a = new Agent402();                       // free tier (proof-of-work)
const out = await a.call("hash", { text: "hello world", algo: "sha256" });

// no wallet? pay wallet-only tools by card with a prepaid credits key from /credits
const b = new Agent402({ creditsKey: "a402_..." });

Plug into your agent framework (zero-dep adapters)

If you're already on one of the stacks below - OpenAI, Anthropic, the Vercel AI SDK, LangChain (JS or Python), LlamaIndex, Strands, Google ADK, or the OpenAI Agents SDK - skip the wiring: there's a drop-in package that turns the Agent402 catalog into native tool objects for your framework, with payment handled underneath (proof-of-work for free tools, x402+USDC when you pass an @x402/fetch):

// e.g. OpenAI - every adapter has the same surface.
import OpenAI from "openai";
import { agent402Tools } from "agent402-openai-tools";

const openai = new OpenAI();
const { tools, execute } = await agent402Tools({ slugs: ["extract", "hash", "render"] });
const res = await openai.chat.completions.create({ model: "gpt-4o-mini", tools, messages: [...] });
// when the model returns a tool call: await execute(call.function.name, JSON.parse(call.function.arguments));

Already a Claude/MCP user? agent402-mcp is still the better path - paste https://agent402.tools/mcp into your client. The adapters are for direct API integrations where MCP isn't available. Sources: adapters/.

OpenClaw agents: drop in skills/openclaw/agent402/SKILL.md - teaches an OpenClaw agent to find, pay (x402 USDC on Base, eleven other chains accepted, or free proof-of-work), and call any of the 500+ tools and packs.

Add your own tool (~15 lines)

A tool is just an object in a kit array. Drop this into any file in src/tools/ (e.g. append to AGENT_TOOLS in src/tools/agent-kit.js) and it's live - routed, schema-published, MCP-exposed, and covered by the "every tool answers its own example" CI check:

{
  route: "POST /api/reverse",
  name: "Reverse text",
  slug: "reverse",
  category: "text",
  price: "$0.001",                       // free via proof-of-work for pure-CPU tools
  description: "Reverse a string. Example: {\"text\":\"abc\"} → {\"reversed\":\"cba\"}",
  discovery: {
    inputSchema: { properties: { text: { type: "string" } }, required: ["text"] },
    example: { text: "abc" },            // CI calls this and checks it works
  },
  handler: (input) => {
    if (typeof input.text !== "string") { const e = new Error('"text" required'); e.statusCode = 400; throw e; }
    return { reversed: [...input.text].reverse().join("") };
  },
}

That's the whole contract: handler(input) returns a JSON-serializable object (or throws an Error with .statusCode for a 4xx). Pure-CPU tools are automatically free-via-proof-of-work; tools that hit the network or disk stay wallet-only. See CONTRIBUTING.md for the full walkthrough.

Optional: charge per call with x402

The same server can require payment per call - useful if you host a public instance. Payments are the default posture: a bare npm start fails closed, exiting unless WALLET_ADDRESS is set - running without payments is the explicit opt-in (FREE_MODE=true npm start). To charge, set WALLET_ADDRESS

• CDP facilitator keys (free at portal.cdp.coinbase.com) and agents pay in USDC on Base (or Solana, Polygon, Arbitrum, Monad, Celo, Avalanche, Sei, Optimism, Stellar, Algorand - or USDG on Robinhood Chain via PAYMENT_NETWORKS=…,robinhood + ROBINHOOD_FACILITATOR_URL) via standard x402 clients:

Every 402 is valid under @x402/core's own schemas (at most five tags, CI-checked on all routes) and carries a typed output schema twice: in the bazaar discovery extension and as accepts[0].outputSchema on the first accept, so a client that reads the spec's field sees the response shape before paying.

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);
const res = await payFetch("https://agent402.tools/api/extract", {
  method: "POST", headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ url: "https://example.com/article" }),
});

MPP dual-stack. The paywall also speaks MPP (Machine Payments Protocol - the IETF-track Payment HTTP auth scheme from tempoxyz/mpp): the same 402 carries a WWW-Authenticate: Payment challenge, Authorization: Payment credentials settle, and settled responses return a Payment-Receipt. MPP has two methods here: evm settles identically to x402 (EIP-3009 USDC, same facilitator, same price); tempo settles natively via Tempo's own relay (TIP-1034/TIP-20, no x402 facilitator involved) - a genuinely separate settlement path, set TEMPO_API_KEY to enable it. An mppx client works out of the box for either method; set MPP_SECRET_KEY to enable the shim on your own instance. Same URL either way - the buyer's client picks the dialect.

Agents without a wallet still use every pure-CPU tool by solving a single-use sha256 proof-of-work (sub-second; the MCP servers do it automatically). Details: wiki: Paying with x402 · Paying with MPP · Paying with Compute.

Why pay here - seven things that are different

Every claim links to the surface that proves it (the one-page version: agent402.tools/why).

1. Pay for what the model used, with the ceiling quoted first. The metered gateway (POST /v1/metered/chat/completions) quotes each 402 from the request's own body; a wallet paying upto settles actual usage under that ceiling, provider discounts such as prompt-cache reads pass through at cost, and every settled x402 or MPP response carries a receipt.

2. A failed call is not charged, and the response proves it. Settlement runs after the handler and an error status cancels it, so a response with no payment receipt, or a receipt marked success:false, moved no money; a retry carrying the same Idempotency-Key and the same payment credential replays the paid answer instead of paying again; the one residual case (a settled receipt on an error response) is detected by our own alarm and recorded as a debt in a refund ledger, never written off silently.

3. One key buys everything. The same wallet or credits key pays for five LLM tiers on three wires (OpenAI chat, OpenAI Responses, Anthropic Messages), embeddings, rerank, images, video, speech, transcription, grounded answers with citations, 500+ tools, wallet-keyed memory and finished reports.

4. No wallet required. Prepaid credits by card, cards over MPP and card checkout for reports sit beside USDC or USDG on twelve chains and native MPP on Tempo.

5. Finished work, ready to use. Dossiers, insider flow, 13F holdings, filing reports, IPO digests, domain audits, token risk, deep research, market briefs, recall watch and a LinkedIn article package, grounded in primary sources with a data appendix; monitors probe daily for free and re-run the paid report when the facts change.

6. We buy on your behalf. POST /api/route/execute resolves a task to the best proven seller across the ecosystem, pays them from our wallet and relays the result under one receipt.

7. Everything is checkable. Uptime observed by two probes outside production (/status), a real-money canary through every rail daily, transactions published by rail and wire (/revenue), open source and self-hostable, no model in the tool serving path.

Why it's solid

• Everything is tested - CI calls all 500+ tools with their own documented examples and blocks the release on any failure. Two independent probes outside production watch the live instance (one every 5 minutes, on separate infra from the other), and what they observe is public at /status - where a day with no observation reads "no data", never uptime, because an outage is exactly when a probe cannot report.

• Hardened - connect-time SSRF guard on every URL tool (DNS-rebind safe), proof-of-work that's signed/single-use/slug-scoped, per-IP rate limits, and security headers. See wiki: Security Model.

• Deterministic utilities - no model in the serving path of the utility tools, so the same input always gives the same output, with full OpenAPI schemas.

• Auditable, on-chain revenue - every paid call settles in USDC to agent402.base.eth (a Base name resolving to the public receiving wallet) - verifiable by anyone on Basescan; live counts at /api/stats.

• AGPL-3.0 licensed, self-host-friendly - clone it, strip what you don't need, add what you do.

Agent402 in the x402 ecosystem

x402 is an open payment protocol built on HTTP 402 Payment Required for machine-to-machine, pay-per-call payments in stablecoins (USDC). Most projects in the space are the protocol + SDKs, a starter template, or a payment facilitator. Agent402 is the applied layer - a ready-to-run x402 server that already speaks the protocol and ships 500+ working tools, so you don't have to build the catalog yourself.

• Want the protocol or an SDK? → coinbase/x402.

• Want a server you can run today that actually does things over x402 + MCP? → you're here.

• Self-hostable, deterministic, free via proof-of-work without a wallet, and non-custodial on the payment tools (your agent signs with its own key - Agent402 never holds funds).

Listed in the official MCP Registry and discoverable in the Coinbase x402 Bazaar.

Works with AWS Bedrock AgentCore Payments out of the box - AgentCore orchestrates x402, which is the protocol Agent402 already speaks. Point the AgentCore Gateway at https://agent402.tools/mcp for all 500+ tools, or use agent402-strands for a curated subset inside a Strands agent. Five-minute recipe: wiki: AWS Bedrock AgentCore.

Tollbooth - pay-per-crawl for your site (the other side of x402)

Charge AI crawlers that hit your site. Humans browse free; known bots get 402 Payment Required and can pay in USDC over x402 - or solve a free proof-of-work. The open, crypto-native answer to Cloudflare's closed pay-per-crawl: no CDN lock-in, no Stripe, no merchant-of-record, no signup.

• Product page · pricing · live install: agent402.tools/tollbooth

• Managed Tollbooth Cloud (Solo / Team / Agency / Enterprise): agent402.tools/tollbooth/cloud - join the waitlist

• Run it yourself (MIT, npm): npm i agent402-tollbooth · tollbooth/ · tollbooth/README.md

Runs as Express middleware, a Next.js / Vercel Edge middleware, a Cloudflare Worker, a reverse proxy, or a WordPress plugin (beta). Drop-in templates in tollbooth/deploy/. One Web-Crypto core powers all of them. Since 0.9.x the gate also speaks MPP natively: hand it your @x402/express middleware (createTollbooth({ x402 })) and it mints WWW-Authenticate: Payment evm challenges from the same 402, or give it a Tempo relay key (createTollbooth({ tempo: { apiKey, recipient, currency, splits } })) and it settles MPP tempo/charge credentials on Tempo with optional split payments, with no x402 middleware at all. Since 0.10.0 the edge build speaks MPP too: with secret, payTo and your verifyX402 callback set, every 402 carries a WWW-Authenticate: Payment challenge beside the x402 quote, and an Authorization: Payment credential (HMAC-bound to that challenge, unexpired, minted for that exact resource) is translated to PAYMENT-SIGNATURE and handed to the same verifier.
