Fia Signals x402 Base USDC token safety and smart contract risk batch API for buyer agents, trading bots, swap routers, and A2A commerce. Screen up to 5 Base/EVM contracts before a swap for contract risk, rugpull, honeypot, liquidity, and market risk. Returns safe/risky/blocked verdicts, scores, warnings, GoPlus and DexScreener evidence, aggregate counts, and a non-breaking 0.50 USDC bundled-risk-pack payable tier in one paid pre-swap call.
Start with a quote-only recipe. Payment signing stays in your project.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
