USDC

The Arc x402 marketplace

Pay-per-call tools for AI agents - settled in USDC on Arc, no signup, no API keys. The wallet is the account.

An open index of the whole Arc 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.

live receipts temporarily unavailable - settlements remain verifiable at explorer.arc.io

A paid canary buys tools over the Arc rail daily - uptime proven with real settlements, not pings.

Agent402 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.

Buy tools with USDC on Arc

0 of our 625 tools take USDC on Arc (624 identity-bound or long-running tools settle on the EVM rails only; 1 tool is offered on Base only), from $0.001 to $3.30 a call, across crypto & onchain data, live public data, skill packs, web & documents, llm gateway, data conversion and more. The catalog page carries the category browser; this page is the chain's ledger.

Sell on Arc

Accept the Arc CAIP-2 network (eip155:5042) in your 402 challenge; an x402 facilitator that supports Arc 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.

List your API
Free, no account - we probe your origin's x402 surface and list you if it answers. Rows are ordered by settled calls, then crawl health.

amount is in the token's smallest unit (6 decimals: 1000 = $0.001); asset is the token's on-chain id. For a live accept on this chain: curl -i https://agent402.tools/api/hash?text=hi
