X402 Notarize

animica.dev · General

Anchor a SHA-256 digest (or a small document, which we hash for you) into the Animica data-availability layer and get back a commitment plus a Merkle inclusion proof anyone can check without trusting us. The record is erasure-coded across shards and committed to a Merkle root; the response carries the commitment, the leaf index and sibling path, and the chain head height and hash observed at the moment of anchoring. Verification is FREE and permanent at GET /x402/notarize/verify/{commitment} — a notarisation nobody can check would be worth nothing. Note precisely what this proves: the record is committed in this node's DA tree under the returned commitment, alongside the head it observed. That is not the same as a timestamp signed by the whole consensus set, and the response says so rather than blurring the two.
