build_ap2_mandate
InactiveTool of AXIS Toolbox — Agentic Commerce Codebase Intelligence
Validate, canonically encode, and optionally Ed25519-sign an AP2 mandate (Intent / Cart / Payment) using the real @axis/ap2 codecs — schema validation (including cart-total arithmetic and intent cross-references), RFC 8785 JCS-style canonical JSON encoding, and detached-JWS EdDSA signing over node:crypto. Pass seed_hex (64 hex chars = 32 bytes) to sign deterministically client-side-supplied key material — AXIS stores no keys; omit it for an unsigned template with encoding only. The signed envelope round-trips through verifyMandate before it is returned. Free, no auth, deterministic (Ed25519 signatures are deterministic per RFC 8032), no side effects. SCOPE HONESTY: conformant to AXIS's TypeScript encoding of the public AP2 mandate schema, verified against self-authored golden vectors — NOT certified against an official AP2 conformance suite or a live network counterparty.
