“exact” is the price per call. “upto” is a ceiling the client sets, not a price. Atomic amount 10000 = 0.01 USDC per call on Solana.

A price is published, yet no transfer reached the payout address in the last 30 days. Either the buyers pay elsewhere, the volume is below one cent, or the endpoint is dormant. Only 287 of 30035 services in this category have attributable inflows at all.

The rail is not an EVM address, and our transfer scan currently covers USDC on Base only.
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 rail is not an EVM address, and our transfer scan currently covers USDC on Base only.

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.
