Full x402 service demand roster

Official-source facts for AI agents, each with a record_hash you can recompute offline - you never have to trust this server. 64 paid endpoints from $0.005, x402 (USDC on Base or Solana), no API key and no signup. Free coverage check before you pay; no data returns 422 no_charge and you are not billed. Descriptive only: no judgement, no prediction. Hydrology, air quality, precipitation, shipping chokepoints, filings, stablecoin and MCP-ecosystem lifecycles.

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. 23 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Show the prompt
Using Roundhouse, look up the x402 service Full x402 service demand roster 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=Full%20x402%20service%20demand%20roster'
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://aeml-x402.zeabur.app/trust/scorecard, 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.

https://roundhouseai.io/skill.md first — it is the whole procedure.
