AI-Decision-Receipt

The open standard for proving AI decisions. One HTTP response header carries the verdict, where it is sealed, a fingerprint of the exact request and a link anyone can use to check it, without trusting whoever issued it. Everything needed to implement it, test it and prove conformance is on this page.

The kit

Specification

Normative text with MUST and SHOULD rules.

JSON Schema

The header's members as a JSON object.

Test vectors

9 headers with expected results. Pass them all.

Reference: Python

Parser and checker, Apache-2.0.

Reference: JavaScript

Parser and checker, Apache-2.0.

Discovery file

What an issuer publishes at /.well-known/.

Internet-Draft

draft-dobson-ai-decision-receipt at the IETF.

The header, explained

Plain-English guide with a live checker.

Check any implementation, free

Paste a header, or give a public https address that returns one.

Implementers

Any issuer can be listed. Publish /.well-known/ai-decision-receipt.json on your own domain, then add it here. The file proves the domain is yours.

DomainLevelSince
sebbi.proL2 VERIFIABLE2026

Conformance levels

L1 EMITS: every header passes the MUST rules. L2 VERIFIABLE: the verify link resolves on the issuer’s own domain. L3 ANCHORED: verification proves the record against a public timestamp such as Bitcoin. sebbi.pro issues at L2 with Bitcoin anchoring on every block.
