Per call. A quote or swap costs $0.001 — no subscription, no API key.

Agents send priced requests to 3Route over x402 or MPP — one quote, one swap, or a batch of thirty on a single wide lane. Meanwhile every new block on each connected chain hands its state to the router as it passes.

Your AI agent can pay with x402 or MPP, independently of the chain it trades on. For frequent requests, use x402 batch settlement or MPP sessions. 3Route processes each new block as it arrives, so quotes use the latest available on-chain state.
