PROTOCOL ADAPTERS
8 STANDARDS

Protocol adapters for PEAC

Each adapter connects PEAC to one external standard: AIPREF for publisher preferences, x402 for payments, MCP for tool context, C2PA for content provenance. They translate between formats so your code stays protocol-neutral.

Adapter ecosystem

AIPREF Adapter

READY

Reads AIPREF files (aipref.txt) and maps publisher preferences to PEAC policy fields. Checks training, scraping, and attribution permissions before issuing records.

HTTP 402/x402

READY

Implements the x402 payment challenge flow: returns 402 with pricing headers, verifies payment proof, issues a signed PEAC record on success. Works with Stripe and on-chain rails.
