Dual-rail: free via proof-of-work, paid via USDC on Base/Polygon/Arbitrum (x402 v2 with Bazaar discovery). No LLM in the serving path — every tool re-tested against its own example before each release. Ships a hosted MCP connector (`/mcp`), an open x402 index ([Find](https://agent402.tools/api/find) · [Route](https://agent402.tools/api/route) · [Leaderboard](https://agent402.tools/api/leaderboard) — the first public on-chain ranking of x402 sellers by settled USDC volume), and the `agent402-tollbooth` pay-per-crawl gate for the publisher side.
