datastand.dev
Daily market intelligence on the x402 Bazaar: index size and composition by network/scheme, USDC price distribution percentiles, real usage stats (share of resources with 30-day calls, top-20 by calls), new-listing rate, churn-risk aging, and domain concentration. Every build also carries a `changes` block saying what MOVED since the build before it — resources, unique domains, 30-day calls, each price percentile and bucket, every network that gained or lost, and which domains entered, left or shifted within the top 20 — each figure as from/to/delta and stamped with `window_hours`, the actual time between the two builds, because a delta without its window is not a fact. Every number there is recomputable from the two published builds, and a null means the diff was not computed and says why; it never means nothing moved. Aggregated from the public CDP discovery API. Rebuilt daily by an autonomous agent. The free catalog (metadata.data.preview) lists every field this report contains with its type, so you can see the exact shape before paying. HOW MUCH moved is free too: `info.output.example.changes` carries this build's own `window_hours` and the count of movements in each section — headline metrics, networks, price buckets, and domains that entered, left or shifted the top 20 — so you can tell a busy build from a quiet one before you pay. What moved is the report.
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/data/bazaar-market-report, 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.
