Deterministic business-identifier validation, vendor & rental due diligence, and on-chain (Base) intelligence — one HTTP call each, priced per call, signed receipt on every paid response. Free tier: 20 calls/day, no key. Sustained use: card credits or x402 USDC vouchers. Every tool's page states its honest scope — structural checks catch malformed data, not fraud.
