Automatic Http 402 Response Detection And Payment Metadata Extraction

via “x402-payment-protocol-negotiation”

The AI agent with a wallet — spends USDC autonomously to get real work done. Apache-2.0, TypeScript.

Unique: Implements the HTTP 402 Payment Required standard as a first-class protocol in the agent runtime, treating payment negotiation as part of the HTTP request/response cycle rather than a separate concern. Automatically handles payment proof generation and submission.

vs others: Most agent frameworks ignore HTTP 402 or treat it as an error; Franklin agents natively understand and execute the payment protocol, enabling seamless integration with future X.402-compliant service ecosystems.
