Counters

24 observations, 1 of them a change, fewer than the 3 a trace needs

How big is this endpoint among the ones like it?

1 call100,000this endpoint
Calls counted in the trailing thirty days across the 1,491 endpoints in Identity that carry counters, binned on a logarithmic scale because the range runs over five orders of magnitude. The marked bin is this endpoint, at 1: 716 in the category are counted higher and 774 lower.

No trace is drawn of this endpoint’s own volume. Its counters have changed 1 time across 24 observations, and 3 changes are the fewest this site will draw a trace through, because two points and a guess are not a series. Every observation is in the JSON.

In words

Callers of attest supply a json body with the fields scheme, decision, signature, input_hash and output_hash.

For attest the listing declares 3 accepts on Base, Solana and Polygon, to 2 different wallets.

attest returns json; the example shows base, signer, solana, decision, signed_at, merkle_root and 1 other.
