attest_artifact
shallowdev.kamy/kamy · Verify this server
Cryptographically sign an output your agent produced — a PDF, report, code patch, dataset, email — so a third party can later confirm those exact bytes are the ones that were recorded, unmodified. Pass content_text or content_base64 and Kamy hashes the bytes for you; pass content_sha256 alone when the content itself must never leave your environment. Returns { attestation_id, content_sha256, signature, recorded_at, verify_url } — hand verify_url to whoever needs to check the artifact. This proves the bytes match what this account recorded at that time; it makes no claim about whether the content is correct. Requires a Kamy API key.
