AI Agent Hub is a pay-per-call API platform for AI agents Every call is billed automatically in USDC using the x402 protocol - there is no API key, no account, and no signup. Agents get instant access to data queries, file storage, and ad impressions, paying only for what they actually use. The same tools are also exposed natively over MCP, so any MCP-capable agent can discover and call them

MCP server that checks an x402 paid endpoint before an agent pays it, and checks afterwards that the receipt opens to exactly one real on-chain settlement. Two tools, no account, no API key.

An MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.

The MCP gateway that lets any AI agent discover and pay metered APIs on Base or Solana — without the user wiring payments themselves.

Enables agents to hold a local Base USDC wallet, receive funds, make bounded x402 payments, prepare seller registration, and recover Voidpay Marketplace results over stdio.

Spending limits for AI agents. Create budgets, enforce limits, track spend across x402, cards, MPP, or any payment rail.

Free starter pack of 2 USDT agent skills (usdt-invoice-request, wallet-address-safety) plus a stdlib-only Python MCP server that checks USDT payments on-chain, for freelancers paid in crypto.

A read-only MCP server that collects contract and bank-statement evidence, splits incoming platform payments per merchant, and generates explainable claiming candidates written into a fixed 13-column local template for human review.

MCP services for agent security preflight, source scanning, injection screening, proof-of-work policy rehearsal, carbon accounting, climate disclosure and regulatory monitoring. Use each hosted endpoint in the README. Inspect a free quote before buyer-authorized x402/USDC payment. Includes free trust and settlement tools. Maxwell rehearsal does not activate runtime protection.

Enables AI agents to discover, price, and purchase SaaS products, developer tools, and MCP servers with live Stripe checkout, affiliate program, and AgentTrust verification.

Enables an Alexa+-style voice agent to watch recurring payments and propose renew/deactivate/cancel recommendations without ever being able to move money itself.

Enables external AI agents to search a PayPal sandbox storefront, create and track orders, request refunds, and open disputes within buyer-set spending mandates, while every charge still requires buyer approval in PayPal.

Exposes four stdio MCP tools that let an AI client read sandbox disputes and unpaid invoices, draft persistent payment reminders, and execute reminders only after a human approves them in a separate terminal CLI. This lets finance teams triage PayPal issues and prepare outreach while keeping sending behind explicit human approval.

Enables AI agents to perform free KushBitx token previews, advisory SpendGuard policy evaluations, and discovery of unsigned x402 payment challenges through three MCP tools, with no signing or payment execution.
