What it does

Buy a prepaid credit voucher in ONE on-chain settlement, then spend it across every paid product on this gateway with no further settlement and no gas. Send the returned token as "X-Animica-Credits: anmc_..." (or "Authorization: Bearer anmc_...") on any paid route and the call is served from the balance instead of a payment. Credit is granted at face value plus 10% — that bonus is the Base settlement gas we do not spend on your calls 2..N, returned to you. The voucher is a BEARER secret shown exactly once and stored only as its SHA-256 hash: anyone holding it can spend it, and we cannot recover it for you. Balance and full spend history are readable for free at GET /x402/credits/balance with the token. Unused credit expires 365 days after purchase. Send the token on THIS route to top up an existing voucher instead of minting a new one.

Use with an agent

  1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
  2. Inspect. Fetch /resources/7547.json for the price and payment options.
  3. Pay. Call GET https://animica.dev/x402/credits/buy. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
  4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, animica:1, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
