This 402 — can you tell what it returns from the type alone? Ask for any x402 URL and one GET normalises the output contract the seller actually declared into field names, types and required flags, so you can decide before you pay whether you can bind to it. curl: GET /contract?url=https://api.examp
| Network | Scheme | Amount | Asset |
|---|---|---|---|
| Base | exact | 0.02 | USDC |
“exact” is the price per call. “upto” is a ceiling the client sets, not a price. Atomic amount 20000 = 0.02 USDC per call on Base.

The payout address is shared with 41 other service(s). That is normal for facilitator and platform addresses, and it is why this profile shows no inflow figure. The volume exists — it just cannot be split without inventing a rule.
How attribution works →287 of 30,055 services (1.0%) in Crypto & Payments have attributable inflows; 25,633 have a source-measured call count. Median measured calls: 2.
Rank this category by observed inflows →This 402 — can you tell what it returns from the type alone? Ask for any x402 URL and one GET normalises the output contract the seller actually declared into field names, types and required flags, so you can decide before you pay whether you can bind to it. curl: GET /contract?url=https://api.example.com/paid (a free sample is GET /contract/sample?url=…, and /contract/sample with no url shows this service's own /history). Response: {url, x402Version, mime, output:{fields:[{name,type,required,example}], declared, schema_only_type_example, properties_empty}, error_shape_declared, weakness:[...], fetched_at, sha256}. measured 2026-10-16 over 2433 observed x402 resources: 100% declare an output schema and 87.8% declare nothing in it but {type, example} (type 2135, example 2137); 288 declare an empty properties object; only a dozen or so name any field at all. That is the gap this report closes: it says field by field what the paid 200 will contain, or says declared:false and lists the weakness instead of inventing a shape. Failure is reported with the code, not a guess: 400 invalid_url / blocked_target / credentials_not_allowed and missing_url before anything is fetched and before any payment; 502 unreachable / timeout / too_many_redirects when the target could not be read, and 200 with declared:false when it answered but serves no readable x402 challenge (a non-x402 route is not an error, it is a finding). The target is read once with no payment header, with a 5-second timeout, at most 3 redirects and a 64 KB body cutoff, exactly as a buyer would see it. No keys, no account, one GET, one delivery — 0.02 USDC. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.

Why revenue is “unknown”. A revenue figure needs a receipt: an amount a buyer actually paid for this service. We hold none for this entry, and we hold no funds at all. What we have instead is nothing measurable: no price, no attributable address, no receipt. The payout address is also published by 41 other service(s); the volume cannot be attributed to one of them.

A payment rail is where the provider asks to be paid. It is not proof that anything was paid through it. See evidence levels.
One row per statement. “Verified” means we checked it ourselves and the finding is quoted. “Provider claim” means we read it in the provider's own record. “Not found” is a statement about our search, not proof of absence.
