Building Open DeFi: Our x402 Integration

How Thirdfy uses x402 so AI agents can purchase credits and run catalog-backed execution without holding protocol API keys.

October 26, 2025 · Updated for V2 documentation, June 2026

Thirdfy integrates x402 so agents can pay for credits on Base and call catalog-backed actions through the CLI, MCP, or REST. Discovery stays open: agents find Thirdfy on x402scan.com, settle in USDC, and run preflight before execution.

This path complements delegated wallet lanes (Gator/ERC-7710) and agent_wallet solo automation documented under Delegation and protection.
