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.

Live 402 challenge

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

      "description": "Europe regional risk pulse made agent-callable. One x402 call returns a regional stress signal (STABLE / MODERATE / ELEVATED with a 0-10 score) built from the macro fundamentals of 12 Europe economies — IMF GDP growth, inflation, current-account balance and government debt — plus FX rates vs USD with each currency's peg status (USD peg / floating / managed), and the regional energy driver (Brent crude, natural gas) that dominates Gulf and North-African fiscal balances. Flags the stressed economies by name with the exact triggers (e.g. Italy: govt debt 137% GDP; Ukraine: current account -15% GDP). The macro/geopolitical read a risk or trading agent needs on the hottest region in the world, served pay-per-call. $0.05 in USDC on Base via x402.

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. 5 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 EuropePulse 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=EuropePulse'
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://europe.lonestaroracle.xyz/pulse, 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.
