Tradebot Risk & Integrity API

Read-only pre-trade and market-data integrity checks for autonomous crypto agents, x402 paid, USDC on Base. Verified route: POST /v1/pre-trade-execution-gate at $0.02, which scores a caller-supplied visible order book for execution admissibility and returns PASS, CAUTION or AVOID with fill ratio, slippage, spread, visible depth and depth utilization. At verification it was given a deliberately thin synthetic book and returned AVOID with fill ratio, slippage, spread, average and worst fill price and visible depth all matching values computed independently beforehand. The sibling route POST /v1/market-data-attestation at $0.01 is listed but not payment verified. The verdict is scoped to visible order book admissibility only and excludes fees, funding, latency, queue position, hidden liquidity and market movement; it never places orders and is not trade advice. Base only.
