The open index of paid APIs for agentic commerce - 3,146 independent sellers on Base alone besides this host, with what they charge and, on Base, what they have actually settled.
Describe the job, not the tool name: FIND searches every indexed tool and shows live results. Resolving is free (GET /api/find); you pay only to execute. This is the neutral x402 index: every seller, not just ours.
Agent402 runs this index and sells 500+ tools, metered models and reports on the same rails. What these figures count.
THIS HOST = run by agent402 · every other seller is independent, found by the open crawl · Chain shows the networks each seller's 402 advertises · tx = settled calls on Base, last 7d, from the seller leaderboard
This host plus every independent seller the crawl finds, the x402 Bazaar discovery listing included, so other venues' listings appear here too. Each origin is re-probed every 30 minutes, and rows are ordered by settled calls, then crawl health.
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). A row's mark names the reason, and /api/index carries it as routerDispatchReason.
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 itemized in it, so these are not lifetime totals.
every rail has its own market page - a seller appears under every chain it accepts, so these do not sum to a distinct total
The Smart Order Router can buy from outside sellers on Base, Algorand, Tempo and Solana, paying on the chain you paid us on, and relays the result.
every gasless EIP-3009 USDC transfer on Base, the authorization x402 settles with, counted chain-wide: most of these are not x402 calls, so this is all such transfers, not x402 volume · machine-readable at /api/x402-economy
Describe the task and the Smart Order Router resolves it to a tool - from this index, ours or anyone else's - then runs it. Candidates are ranked by how well they match, then crawl health, buyers and price; a model can make the final pick (the full rule). It buys from external sellers and resells the result to you.
# free to resolve; running a result costs the router price in its executeVia

No editorial gate and no pay-for-placement. A row can be corrected or withdrawn on request (see below), and a seller that stops answering is marked unreachable.
A directory of services that accept x402 payments, so an AI agent can find something to buy and pay for it in one round trip without an account. This index lists every seller it can crawl, not only our own tools, and publishes the tool counts, settlement chains and crawl health it observes.
By serving x402 challenges and registering its origin with POST /api/index/register, which crawls it at once, or by appearing in the x402 Bazaar discovery listing, which the crawler re-reads every hour. Listing is free, there is no review queue, and there is no pay-for-placement.
A rolling success rate across recent crawls of a seller's manifest and 402 challenge. One bad hour does not delist anyone, and a new seller is not penalised for having no history. The Smart Order Router uses it to break ties and to route around sellers that are down.
Write to [email protected]. Every figure here is a reading of public data - the seller's own manifest and 402 challenges, plus on-chain settlements - taken at the scan time shown, so it can go stale or fold to the wrong operator. We re-scan and correct or withdraw a row on request.
Tool counts are what a seller advertises; settled volume is what buyers actually paid for. A large catalog with no settlements has not found buyers yet, and a small catalog with heavy volume has found exactly the right one. Both numbers are shown so you can see the difference.
