Project information

P3 Agentic Registry SDK is the off-chain companion to the Pearl Path Protocol (P3), the smart contract layer for Pearl Digital Agentic Registry

P3 is purpose-built for the machine economy: gasless x402 and HTTP-native settlement, autonomous agent micropayments, and yield-bearing stablecoins — all under pre-settlement compliance enforcement.

This SDK provides the tooling for AI agents and their Principals to interact with the Agentic Registry and execute within the protocol:

DelegationCredential Builder — DSL for constructing Know Your Agent (KYA) credentials that define an agent's scope, quantitative value limits, and validity period.

Mandate Seal Generation — Canonical serialization and Keccak256 hashing that produces the Proof-of-Agency (PoA) hash stored on-chain by registerAgent(). Hash output is byte-identical to the Solidity equivalent.

EIP-3009 Signing — transferWithAuthorization helpers for gasless, concurrent x402 micropayments using PRLUSD and FLASHD without holding native gas tokens.

Boundary Policy Engine — Validates agent actions against the limits and constraints defined in their DelegationCredential before submission.

MCP Tooling — Model Context Protocol server and tools enabling AI agents to autonomously interact with the Agentic Registry, build credentials, and execute payments within their delegated authority.

Agents operate autonomously but never independently — always anchored to a verified Principal, always within the boundaries of their Proof of Agency.
