🟢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.
Eingabe-Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟢get_piece(id)
Get full metadata for one seal by id ("01".."12"): the canonical authorization record, its sha256, image URLs, and mainnet mint transaction.
Eingabe-Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "Piece id, e.g. \"01\""
}
},
"required": [
"id"
],
"additionalProperties": false
}🟢get_buy_transaction(id, buyer_address)
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.
Eingabe-Schema
{
"type": "object",
"properties": {
"id": {
"type": "string"
},
"buyer_address": {
"type": "string",
"description": "Optional: your XRPL address, inserted into the template"
}
},
"required": [
"id"
],
"additionalProperties": false
}🟢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.
Eingabe-Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}⚪verify_seal(id)
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.
Eingabe-Schema
{
"type": "object",
"properties": {
"id": {
"type": "string"
}
},
"required": [
"id"
],
"additionalProperties": false
}🟢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.
