datastand.dev
What just launched in the x402 economy: the most recently listed or reindexed Bazaar resources, newest first, with price and adoption stats. Track new competitors, spot fresh capabilities to consume, or watch a category fill up. `offset`/`limit` page through the matches, up to 100 rows per call. Read `window_complete` before you read `count`: this feed draws from a bounded pool of the newest listings, and `listed_at` is the Bazaar's re-index stamp rather than a first-published date, so on a busy index that pool spans hours rather than days. Ask for `days=7` and you will usually get `window_complete: false` and `corpus.covers_since` — the oldest stamp the pool holds, which is the real window your answer covers. That distinction is the difference between "the market was quiet this week" and "this feed only reaches back an hour", and both the flag and the bound are on the free catalog listing (`info.output.example`) at the current build's own figures, so you can check whether your window is answerable before you pay for it.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
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
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 32 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

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/bazaar/trending, 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.
