datastand.dev
Keyword search over the x402 Bazaar discovery index (the ~8,000 most-used of 15k+ resources, refreshed daily): find services by text query with price and usage filters, ranked by unique payers. The discovery endpoint itself has no search — this is it. Every match is reachable: `count` is the full number of hits and `offset`/`limit` page through all of them, up to 100 rows per call. A page past the end of the results is refused with a 400 and settles no payment. Priced per row: $0.005 covers the default 20 rows, each further row adds $0.0002, and a full 100-row page costs $0.021. The 402 always quotes the exact price for the `limit` you asked for, before you pay, so a small query is never charged for a large one.

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.

Using Roundhouse, look up the x402 service datastand.dev 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=datastand.dev' 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://datastand.dev/api/search/bazaar, 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.
