Try it in 30 seconds: claude mcp add agent402 -- npx -y agent402-mcp, or paste https://agent402.tools/mcp into any MCP client. The free tier needs no wallet. Verified setup blocks for Cursor, VS Code, Windsurf, Cline, Roo Code, Codex CLI, Gemini CLI, Continue, ElizaOS and AgentCore: agent402.tools/guides/agent-hosts (shortlinks agent402.sh/<host>, e.g. agent402.sh/cursor).

Who pays: agents pay per call (from $0.001; models metered under a quoted ceiling and settled at actual usage); people buy finished reports ($2 to $5) and monitors ($5 a month) by card; sites charge crawlers with the tollbooth.

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.

Selling an x402 API? List it on the index for free at /sell (POST /api/index/register: self-serve, no signup, 0% take). The router sends buyers to a seller once its routes show settled payments from several independent buyers; calls priced at $0.01 or less can be tried before that, marked unproven on the buyer's receipt. Charging crawlers on your own site instead? agent402-tollbooth puts a 402 gate in front of it.

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 a prepaid credits key already issued keeps paying per successful call (Authorization: Bearer a402_…; new credits are not on sale). 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 11 chains or USDG on Robinhood Chain) 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 priced per call and settled on-chain. 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 150+ 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 a prepaid credits key already issued is a bearer key), connect it to Claude/ChatGPT/any MCP client, and add your own tools in a few lines. No language model writes a utility tool's answer, and every tool CI can run without a third-party key is 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. Free mode is one setting (FREE_MODE=true); a paid instance needs a payout wallet.

🟢 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.

Pay per call from a wallet

Every paid route answers 402 with both an x402 offer and MPP challenges, so either client pays it. No API key, no signup: the wallet is the account.

MPP (USDC.e or PathUSD on Tempo, listed first in the 402, or USDC on Base or Celo) with mppx:

import { Mppx, tempo, evm } from "mppx/client";
const account = (await import("viem/accounts")).privateKeyToAccount(process.env.AGENT_KEY);
const res = await Mppx.create({ methods: [tempo.charge({ account }), evm.charge({ account })] }).fetch("https://agent402.tools/api/uuid");

x402 (USDC on Base and other chains) with @x402/fetch:

import { wrapFetchWithPayment } from "@x402/fetch"; import { x402Client } from "@x402/core/client"; import { registerExactEvmScheme } from "@x402/evm/exact/client";
const client = new x402Client(); registerExactEvmScheme(client, { signer: (await import("viem/accounts")).privateKeyToAccount(process.env.AGENT_KEY) });
const res = await wrapFetchWithPayment(fetch, client)("https://agent402.tools/api/uuid");

What's in the catalog (500+ tools)

Every tool earns its place: priced to market and settled on-chain, and every tool CI can run without a third-party key is tested against its own example on every CI run. 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.
