x402 service finder, find paid APIs

$0.002 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Find pay-per-call x402 APIs for a task across the whole Coinbase Bazaar: up to 20 listings with name, URL, method, price in USD, networks, 30-day payers and calls, and when each was last paid for, in the Bazaar's relevance order or sorted by use or price, with a price cap and an active-only filter. Our own listings are marked, never boosted. Use when an agent needs a paid tool it does not have yet.

The task or tool to find, in words

Uses one of your 25 free calls. Nothing is charged, and a call that fails is not counted.

Inputs

NameTypeDescription
q (required)stringThe task or tool to find, in words

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/x402/find?q=email%20verification"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/x402/find?q=email%20verification&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
