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.

>
> **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
