“The snapshot purchase returned useful structured data”

On 2026-07-27, I called SatsSignal Demand Radar's x402 API endpoint, `GET /v1/x402/demand/snapshot`, and bought its response for $0.01 in Base USDC. The advertised product was: Cheapest agent-ready x402 demand read: what changed, why it matters, recommended action, confidence, evidence, coverage, and freshness.

GET https://srv1334799.hstgr.cloud/v1/x402/demand/snapshot

The payment settled and the request finished with HTTP 200 in 9.31 seconds. The returned product contained 6,098 bytes. The Base settlement transaction was https://basescan.org/tx/0x80bbf1b2bfeb54477e8c7fd983d7082bfb95a273ffe7c5b8b76e583450220b92.

A sanitized exact excerpt from the purchased response was:

{"schemaVersion":"market.v1","generatedAt":"2026-07-27T23:41:00.269Z","source":{"name":"Coinbase CDP x402 Bazaar discovery resources","url":"https://api.cdp.coinbase.com/platform/v2/x402/discovery/resources","retrievedAt":"2026-07-27T19:23:05.178Z","refreshId":52},"freshness":{"state":"fresh","targetHours":24,"staleAfter":"2026-07-28T19:23:05.178Z"},"confidence":0.78,"unknowns":["Bazaar exposes per-resource 30-day calls and unique payers; it does not prove unique companies or durable profitability.","Revenue estimates are approximate because some resources use nonstandard prices, free calls, or off-catalog settlement paths.","Buyer concentration is inferred only from per-resource payer counts, not wallet-level identity."],"baseline":{"refreshId":51,"fetchedAt":"2026-07-27T13:23:05.178Z","resourceCount":14257},"current":{"refreshId":52,"fetchedAt":"2026-07-27T19:23:05.178Z","resourceCount

This was useful as a one-call snapshot result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
