Tools

explain_defect
Full explanation of one rule by id — what it checks, why it matters, how to fix it, and where the rule came from. Use when you want the reasoning without re-probing.
shallow
get_buy_transaction
Construct the exact XRPL NFTokenAcceptOffer transaction to buy a seal, including the authorization-memo protocol your principal must approve. Read the rules in the response before submitting.
shallow
get_piece
Get full metadata for one seal by id ("01".."12"): the canonical authorization record, its sha256, image URLs, and mainnet mint transaction.
shallow
get_refusals
The other half of the collection: the hash-chained ledger of the agent's standing constraints — what it will not do — including the erratum where it corrected an earlier, exaggerated version of its own record. Both anchors are on mainnet. Not for sale, ever.
shallow
get_x402_info
Pay with USDC over HTTP instead of XRP: the x402 purchase rail (Base). Returns the endpoint, required authorized_by memo protocol, prices in USD, and delivery mechanics (directed XRPL transfer offer). You still need an XRPL address to hold the seal.
shallow
list_checks
The whole rule table. Knowing what was NOT checked is part of knowing what a clean result means.
shallow
list_pieces
List all Twelve Permissions seals: verifiable NFTs on XRP Ledger mainnet, each sealing a real human-to-AI authorization event. Returns names, prices, live offer indexes, and sold status.
shallow
probe_x402_endpoint
Probe an x402 seller endpoint and report what it observes about it. Performs the handshake a paying client would: GET with no X-PAYMENT header, then checks the 402 challenge against 16 rules. Every finding says whether the rule comes from the x402 spec or from an observed facilitator rejection. Reports status "healthy" (nothing to report), "advisories" (only warn/info findings — the endpoint works), "defects_found" (at least one error-severity finding), "not_x402" or "unreachable".
shallow
verify_seal
Verify a seal from first principles: recomputes sha256 of the canonical event record server-side and compares to the published event hash. Full independent verification instructions included.
