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.

GET api.roundhouseai.io/v0/endpoints

Show the prompt

Using Roundhouse, look up the x402 service ApiToll Crypto Sentiment 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=ApiToll%20Crypto%20Sentiment'
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://crypto.apitoll.cloud/v1/crypto/sentiment, 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://app.roundhouseai.io/dashboard/team.

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