Aggregates spot order book depth and returns bid/ask notional within 10/25/50/100 bps of mid, signed imbalance in [-1,1], largest liquidity walls and a directional signal. First 3 calls per day free, then 0.02 USDC per call via x402.
Trading pair such as SOL-USDT, BTC-USDT, ETH-USDT
Payment proof: USDC tx hash on Polygon or Base (0x...) or Solana tx signature. Omit on the first call to receive the 402 payment instructions, pay, then call again with the proof.

}Free to call. Returns the best route and an unsigned transaction, and for Solana swaps a rug-pull risk check of the output token (mint/freeze authority, token-2022 traps, holder concentration) so agents do not buy honeypots. Same-chain Solana swaps route through Jupiter with a referral fee account. Cross-chain and EVM swaps route through LI.FI with an integrator fee. The response contains a serialized unsigned transaction to be signed and broadcast by the caller. A 30 bps platform fee is embedded in the route.
