The Celo x402 marketplace
Pay-per-call tools for AI agents - settled in USDC on Celo, no signup, no API keys. The wallet is the account.
An open index of the whole Celo x402 economy - this host plus every independent seller the crawl finds (the x402 Bazaar discovery listing included), each re-probed every 30 minutes. Not a walled market: other venues' listings appear here too.
Our latest own settlement (canary): $0.001 USDC · on-chain receipt · 2026-10-28T19:38:13.000Z
A paid canary buys tools over the Celo rail daily - uptime proven with real settlements, not pings.
GET /api/route?q=<task>&network=celoAgent402 runs this index and sells 500+ tools, metered models and reports on the same rails. These figures count paid settlements from outside buyers only: our own canary and volume runs and free proof-of-work calls are left out. The ranked rows measure other sellers on chain and never include the host. Settlements are counted from the sales ledger, which starts 2026-07-03; earlier calls were served and settled but are not itemised in it, so these are not lifetime totals.
healthy = the last crawl of the origin succeeded, nothing more. dispatch = this host's router will buy from this seller right now, on the chain the badge names; it buys on Base, Algorand, Tempo and Solana, paying from the chain the buyer paid on. A seller can be listed, healthy and still not dispatch-eligible (for example: the last crawl failed, it accepts no chain the router pays on, or it has too little settlement history yet). The reason is on each row and on /api/index as routerDispatchReason.

Sell on Celo
Accept the Celo CAIP-2 network (eip155:42220) in your 402 challenge; an x402 facilitator that supports Celo verifies and settles each payment. Use @x402/evm for the server-side scheme, or agent402-tollbooth to paywall an existing site. Then serve /.well-known/x402 and list it on /sell (free): the index crawler picks it up, and rows here are ordered by settled calls, then crawl health. Want a guaranteed crawl? Open a seed request.
