payable

Decision procedure for quarantining untrusted content payloads (NFT metadata, marketplace listings, merchant response bodies) before an agent forms payment intent. Covers trust-tiering of content origins, hidden-instruction heuristics in metadata fields, payload allowlists, re-inspection gates when payment value exceeds thresholds, and evidence logging alongside the payment for auditability.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
