  • web.search

    Paid ($0.01/call): Live web search: ranked results[] of {title, url, description (the snippet, plain text), age, publishedAt (ISO)} from an independent search index as clean JSON - fresh pages your model's training cutoff has never seen. Optional freshness filter (pd/pw/pm/py = p

  • web.answer

    Paid ($0.08/call): AI-generated answer to a natural-language question, grounded in live web search results with source citations. Returns clean prose plus a structured citations array (URL, snippet, favicon) - backed by an independent search index, not the model's training data.

  • memory.write

    Paid ($0.001/call): Persistent key-value memory for agents, scoped to the paying wallet. Your x402 payment IS your authentication: the wallet that pays owns the namespace. No signup, no API keys. Exact-key storage for structured state. For retrieval by MEANING rather than key, us

  • decide.plan

    Paid ($0.010/call): Describe a job and get a call-ready plan: which tools, across this catalog and outside x402 sellers with a recently verified 402, solve it end to end, in what order, with fallbacks and input params that validate against each tool's schema.

  • decide.execute

    Paid ($0.001/call): Run a decision's plan (decisionId from POST /api/decide), or a free plan sketch (steps), through Agent402: first-party steps run directly, third-party steps are bought from the seller and resold to you at Agent402's price (paid with a wallet on Base; prepaid c

  • demand.request

    [free] Report a capability the 500+ tools do not cover, after catalog.search or catalog.find found nothing that fits. Requests are clustered by need, and frequent ones get built. Records demand only: it runs nothing. Same intake as POST https://agent402.tools/api/wish; aggregate

    [free] Describe this connector: the tools it lists, how to install (Claude Code / Cursor / npm), free vs paid tiers, and discovery URLs.

  • decide.feedback

    [free] Report whether one step of a decide.plan decision worked (success or failure, optional 1-5 quality and latency). Needs the decisionId and feedbackToken that decide.plan returned; one verdict per step, a later report replaces it. Reports feed tool reliability in future rank

Agent402: 500+ tools, metered models and finished reports for AI agents

Live at [agent402.tools](https://agent402.tools).

The paid door for AI agents: 500+ tools, metered models and finished reports, paid per call in USDC over x402 and MPP, or by card. The applied layer of Agentic Finance. Open source, self-hostable, MCP-native.

Operated by Havok Holdings LLC · Live · Why pay here · Receipts · Status · Security · Company

Try it in 30 seconds: claude mcp add agent402 -- npx -y agent402-mcp@0.13.28, 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, Paperclip, HarnessRouter and AgentCore: agent402.tools/guides/agent-hosts (shortlinks agent402.sh/ , 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

$0.05 or less on Base (up to $0.25 a day per seller and $5.00 a day in all) or

$0.01 or less on Solana 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 pays per successful call on Agent402's own services

(Authorization: Bearer a402_…; /credits says whether

packs are 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 12 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 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](https://x402.org) (USDC on Base, Solana, Polygon, Arbitrum, Monad, Celo, Avalanche,

Sei, Optimism, Arc, Stellar & Algorand, plus USDG on Robinhood Chain - 13 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](https://agent402.tools) · 📖 [Wiki](https://github.com/MikeyPetrillo/Agent402/wiki) · 📦 [npm](https://www.npmjs.com/package/agent402-mcp) · 🔌 [MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=io.github.MikeyPetrillo/agent402) · 🧩 [Hosted MCP connector](https://agent402.tools/mcp)

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@0.13.28

in Claude Code: claude mcp add agent402 -- npx -y agent402-mcp@0.13.28

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 Dockerfile. Optional plugins are auto-detected via env: add Redis → REDIS_URL enables the upstream r
