# YourAITools: the opposite marketplace for AI agent tools (x402)

> Markdown version of https://youraitools.co/. A directory of AI tools, APIs and agent services you can pay in crypto, mostly USDC over the x402 protocol on Base and Solana. Every listing links to a public source we checked; x402 listings are verified with our own unpaid 402 probe.

## The opposite marketplace
- **Paid straight to the builder:** you pay each listed tool directly, to its own wallet. We don't process or hold those payments; we earn only from optional, labeled extras.
- **No signup:** pay per call in USDC over x402. Our own tools also take prepaid credits (card or crypto), no account.
- **Every number public:** prices from our own live 402 checks, a free dataset, public stats for our own tools (https://api.youraitools.co/stats/v1/tools, schema https://api.youraitools.co/stats/v1/schema.json), and public stats on every listing page from one unpaid check per day, measured since Oct 27, 2026 (https://api.youraitools.co/stats/v1/listings/{slug}, schema https://api.youraitools.co/stats/v1/listings/schema.json).
- **Never ranked by payment:** lists are A to Z; paid spots are labeled Featured or Sponsored and never change the order.
- **Agent-first:** llms.txt, /.well-known/agents.json, /for-agents, listings.json, and the MCP Hub: one remote MCP server for all 36 of our tools (https://api.youraitools.co/mcp/hub).
- **Pay only if it works:** on our own tools, failed tool calls aren't charged: credits are refunded automatically, and x402 payments settle only after a successful response.
- **Sell your own API through us (live):** one free POST to https://api.youraitools.co/listing/v1/submit, 0% cut; buyers pay your own payTo directly and we never hold funds. Spec: https://api.youraitools.co/listing/v1/submit/openapi.json
- Coming soon: a trust score on every listing (after 7+ days of data, from about Nov 3).
- Outbound click counts, counting since Oct 30, 2026 (public feed: https://api.youraitools.co/stats/v1/clicks). /tools has an opt-in "Most used" sort by them; A to Z stays the default.
