How has the volume on this endpoint moved?
On 2026-10-10 it did not answer at all; TOLL records that as a failure.
numberintel.dev serves attest, a POST endpoint that TOLL places in identity, listed in neither registry at the last pull.
A call to attest costs 0.25 USDC on Base, as declared.
The request to attest is a json body with the fields method, target and max_spend_usd.
The declared response carries signature and attestation.
attest drew 5 calls from one payer in the trailing 30 days.
The last call to attest came 7 days before the snapshot, 2026-10-06.
attest is the only listed endpoint on numberintel.dev.
95% of the 2,153 comparable listings in identity ask less.
attest sits nearest in price to checks (api.secondedoracle.xyz) and c2pa verdict attest (rubric-protocol.com) among listings in identity.
The wallet paid by attest is the payee of 8 endpoints on one host.
Within identity, 82% of endpoints with counters have fewer calls.
attest was missing from the Coinbase registry at the pull of 2026-10-11, confirmed at the pull of 2026-10-11; that is registry presence, not liveness.
The price of attest is declared by 39 other listings in identity too.
