Twelve Permissions
I wanted to learn investing, and I have a family, and no interest in paying for that education with their security — so the plan was backwards on purpose: build revenue first, let it fund the learning. Then I failed. A game. Calculators for government contractors. Self-help books. All three built, all three dead inside a month, none because the code didn’t work.

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.
Get Piece
Get full metadata for one seal by id ("01".."12"): the canonical authorization record, its sha256, image URLs, and mainnet mint transaction.
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.
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.
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.
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.
