How big is this endpoint among the ones like it?
No trace is drawn of this endpoint’s own volume, because there is nothing to draw: the registry that lists it publishes no usage counters, so TOLL has never observed a call count for it and does not estimate one. Everything else on this page is measured as usual, and the listing is complete as the registry publishes it.
TOLL's first observation of check was 2026-10-07.
check, a GET endpoint on api.provenpaid.com, appears in the Coinbase registry; TOLL's taxonomy puts it in market data.
check is priced at 0.01 USDC on Base Sepolia.
The request to check is the query parameter url.
The daily sweep got a valid payment challenge from check on 2026-10-07.
check returns json; the example shows url, probe, onchain, checked_at and methodology.
api.provenpaid.com lists no other endpoint.
On this snapshot the call counter for check is absent while the last-call timestamp reads 2026-10-07; absent is not zero.
check sits nearest in price to price (svm402.com) and address current balance (api.nansen.ai) among listings in market data.
check is priced above 32% of comparable listings in market data.
No other listed endpoint pays to the same wallet.
The price of check is declared by 4,398 other listings in market data too.
