Repair one x402 route's Bazaar discovery metadata in one call. Send a resource URL and one real sample output; get the defect report plus a complete discovery package — full output schema inferred from the sample, a sub-500-char description with a use-when sentence, OpenAPI and well-known snippets,
The payout address is also published by 47 other service(s); the volume cannot be attributed to one of them.

Daily history →. Observed transfers show value arriving at the payout address; they do not establish service revenue.
Receiving wallets are payment addresses published for this service. Sending wallets transferred funds to an exclusive receiving address; this alone does not prove a purchase or identify an agent.

No sending wallet addresses have been retained for this service. Buyer wallets are unknown; daily totals and reported payer counts do not reveal their addresses.
Coverage includes retained scans only, not every historical transaction. Earlier daily totals cannot recover sender addresses. Sender lists exclude shared receiving wallets, whose transfers could belong to another service. A provider address does not establish wallet ownership.
Sorted by source-measured calls, not by our opinion. The right-hand figure is observed inflow, which stays empty for peers whose address is shared.

Chosen by category and by whether we have measured them, not by who pays us. A sponsored placement in this list is labelled as such.

“exact” is the price per call. “upto” is a ceiling the client sets, not a price. Atomic amount 500000 = 0.5 USDC per call on Base.

Attach package.extension as the route's Bazaar discovery extension:\n extensions={\"bazaar\": package[\"extension\"]} on the same route config.\n The extension passed validate_discovery_extension and\n validate_discovery_extension_spec at generation time.\n3. Replace the resource entry in your /.well-known/x402 manifest with\n package.well_known_snippet, and merge package.openapi_snippet.paths into\n your OpenAPI document.\n4. Keep the manifest accepts IDENTICAL to your live 402 challenge \u2014 directory\n validators read the two against each other and reject mismatches.\n5. Metadata alone never lists you: settle one real payment through the CDP\n facilitator (CDP Bazaar / Agentic.Market) or the PayAI facilitator (PayAI\n index) and that index catalogs this route; re-settle at least every ~30 days\n or the listing ages out.",

Examples are the provider's own, not a call we made.
The payout address is shared with 47 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 →289 of 30,801 services (0.9%) in Crypto & Payments have attributable inflows; 26,278 have a source-measured call count. Median measured calls: 2.
Rank this category by observed inflows →Repair one x402 route's Bazaar discovery metadata in one call. Send a resource URL and one real sample output; get the defect report plus a complete discovery package — full output schema inferred from the sample, a sub-500-char description with a use-when sentence, OpenAPI and well-known snippets, paste-in instructions — that ships only after passing both x402 SDK validators. Use this when your listing is hollow, invalid, or invisible in the Bazaar.

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 an activity value of $1.00 — the source's call count multiplied by the published price. That is what the list price implies, not what anyone paid. The payout address is also published by 47 other service(s); the volume cannot be attributed to one of them.
