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. The response returns the top N and carries matched for how many scored.
• Leaderboard - GET /api/leaderboard is the public on-chain ranking of x402 sellers by Base USDC settled volume - calls served, totalUsd, unique buyers per seller. It returns the top N, never the whole board (25 by default, 50 the ceiling; totalSellers carries the full count). 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. 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.

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):
