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.

“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.

Examples are the provider's own, not a call we made.
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 →289 of 30,592 services (0.9%) in Crypto & Payments have attributable inflows; 26,125 have a source-measured call count. Median measured calls: 2.
Rank this category by observed inflows →Send one x402 endpoint URL, get a verdict: alive or dead, the exact price and payTo it charges right now, and what changed since your last look. One GET, no key. Agents call this before paying someone else. The call answers all three: alive (with the reason when it is not), the probe facts (HTTP status, latency, redirects, bytes, cutoff), the exact 402 the target serves right now (amount, asset, network, payTo, maxTimeoutSeconds, required fields), response_shape (what it actually answered), history (uptime reached/of, challenges seen, changes_since_previous) and delivery_evidence. The target is fetched once per paid call, with no payment header, so the 402 you read is the one a buyer faces. By specification: a 5-second timeout, at most 3 redirects, a 64 KB body cutoff, and a refusal — before any payment — of internal, private or link-local hosts, non-web ports, URLs over 2048 characters and URLs that embed credentials. One GET, one probe, one delivery. 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.

The payout address is also published by 41 other service(s); the volume cannot be attributed to one of them.
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.
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.
