An API that proves a cheaper bridge route, for AI agents
Recta compares cross-chain stablecoin routes at the same chain state, proves the saving against the route your agent would use anyway, and charges 5 % of the saving it verifies on chain. Free evaluation, no API key.
What it does
Before an AI agent moves USDC, USDT or BTC from one blockchain to another, it asks Recta with the route it would use anyway (for example LI.FI, Across, Stargate or CCTP). Recta reads every route it knows at the same anchor block and answers with the cheapest route it can prove, the saving as a lower bound, and the fee: exactly 5 % of the saving it later verifies on chain. If there is no saving, the answer says so and costs nothing.
- No API key and no account: the agent signs its request with its own wallet (EIP-191), and Recta never holds a key.
- No prepayment and no credit: the fee is pulled only after the saving is verified, in USDC on Base, capped by an authorization the agent signs.
- Evidence: verified savings are published with both transaction hashes; when the agent's route was already the best, Recta can return a signed best-route certificate.
