Animica

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.

The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

Provider

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Hand this page to an agent

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.

GET api.roundhouseai.io/v0/endpoints

This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 26 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Open skill.md
Show the prompt
Using Roundhouse, look up the x402 service Animica and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=Animica'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://animica.dev/x402/credits/buy, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
