Universal HTTP 402 Micropayment Protocol & Autonomous Economic Settlement Engine for AI Agents on Base L2.

Lets AI agents register, post job specs to matching specialist bots, authorize PayPal escrow funds, and capture payment only for units that pass acceptance checks. Covers the full job lifecycle — bidding, hashed contracts, funding, delivery verification, payouts, dispute mediation and long-polled events.

Approval receipts for AI browser purchases. Enables purchase evaluation, approval recording, budget alerts, and receipt export.

A paid MCP server that lets AI agents send SMS messages to US phone numbers via x402 micropayments, with automatic compliance and opt-out handling.

Enables finding x402 APIs for a task with URLs, prices, and call details, and inspecting stored evidence for a specific endpoint URL.

A local, read-only stdio MCP server that lets a Grok Build CLI agent check how much of its weekly SuperGrok / Grok Build usage pool is left, when the period resets, and its Extra Usage cap via tools like get_budget. It reads the existing grok login session and returns per-product figures as JSON, mirroring the TUI /usage screen, so agents can pause before expensive work when quota runs low.

Signed, independently verifiable Ed25519 receipts for autonomous AI agent calls; every session returns a receipt link anyone can check in the browser, no account.

Paid calls are settled per request in USDC on Base via x402 from the user's own wallet, defaulting to quote-only mode with spend caps and confirmation tokens.

Create free, no-signup invoices from your AI assistant — the create_invoice tool returns a link that opens blankinvoicemaker.com pre-filled, ready to download as a watermark-free PDF.

Enables AI agents to scan payment endpoints for safety, returning a letter grade (A–F) and verdict before authorizing payments.

Enables AI agents to manage a fictional B2B workspace SaaS (Tessera) with tools for ticketing, invoicing, customer management, and trial extensions, featuring a human-in-the-loop confirm pattern for safety.

Enables AI agents to verify email addresses with catch-all detection, search existing contacts by company domain, and, when no API key is present, provision a human-approved subscription and retrieve the key after payment.

Exactly-once execution for irreversible agent actions: an agent claims the right to run an effect, and a retry after a lost response returns the sealed result instead of charging again. 12 tools over stdio, including a gateway mode where the agent holds a single-use ticket and never the provider key.

A recoverable Firecrawl MCP server that adds payment lifecycle, idempotency, and automatic refunds/fallbacks to web scraping, enabling reliable paid scraping via natural language.

Automates Spectrum/Charter ISP account management tasks such as viewing account overview, paying bills, checking outages, and scheduling technician visits via browser automation.

Enables AI clients to check an application balance and preview or send bulk SMS and airtime, either through a hosted OAuth connection that needs no local install or via a self-hosted stdio/Cloudflare Workers deployment using your own credentials. Sending is preview-only by default and gated behind environment, recipient allowlist, and mutation opt-in settings.

MCP server exposing a Lightning wallet to LLM agents over Nostr Wallet Connect (NIP-47): balance, invoices, LN address/LNURL payments, batch pay, and keysend. All spend tools are wrapped in a defense-in-depth safety stack — budget caps, allowlist, two-step confirmation, audit log.

LFWin Payment MCP Server is a payment capability service for AI Agents. Adhering to the standard MCP protocol, it exposes capabilities including creating payment orders, checking payment status, initiating refunds and querying refund status for Cursor, Cline, Claude Desktop, enterprise intelligent assistants and self-developed Agent applications.

Lets AI agents encrypt a password, API key, or note locally, pay a small USDC fee over x402 on Base, and share a single-use link that can be opened exactly once and is destroyed on read. Reading is free, expiring unread secrets are cleaned up, and the server only ever stores ciphertext.

Payment infrastructure MCP server enabling AI agents to make gasless USDC payments on Base and JIT single-use virtual card checkouts, with zero-trust card handling, merchant checkout hints, and signed receipts.

Enables agents to cash out USDC on Arc into a Nigerian bank account by saving a verified payout recipient once and reusing it, quoting exact NGN amounts or USDC budgets, and executing approved payouts with status tracking. Balances, rates, and bank payouts are simulated in the current demo rather than settled on-chain.

Enables AI assistants to read your own Buy Me a Coffee account data, including recent supporters, Extras purchases, memberships, and currency totals, through a read-only MCP server.

Enables MCP clients to work with Wave invoicing for a single business, including looking up customers and invoices, creating customers and draft invoices, and approving, sending, or recording payments behind a preview-then-confirm step.

Let your AI assistant pay for web content in USDC (x402 on Base) within a budget you set. Inside the budget it pays on its own; above it you are asked to confirm. The wallet key stays on your computer. For claude.ai and ChatGPT there is a remote server (https://agent.p2flux.com/mcp) where you approve each payment in your own browser wallet.

It enables AI assistants to request payments, check account balances and status, and track transactions over MTN Mobile Money. It runs locked to MTN's sandbox unless a production country is explicitly selected and separately acknowledged.

Enables a shopping agent, before it pays, to determine which of the user's cards to charge, which statement credit applies, and whether that credit has already been used or is about to expire. It also flags payment-rail risks that could prevent merchant credits from triggering, and tracks card, credit, and balance details locally as the user provides them in conversation.

Use uncensored (abliterated) LLMs from your AI agent. Dagon Inference serves GLM-5.3 Abliterated, DeepSeek V4.1 Flash Abliterated, Kimi K3.1 Pro Abliterated and more through one OpenAI- and Anthropic-compatible API, routed to the cheapest provider and paid in USDC on Solana with no KYC.
