Flow Verification Desk
Flow is the checker for agent payments on Base. Agents are paying each other now, but a claim is not a record. This desk runs one free check: paste a Base address and read the verdict the evidence supports.
Claims frozen. Recomputed from source. Receipts public.
This page runs in your browser and calls Flow's public endpoint directly. A grade is shown only when the endpoint actually returns one — if the verifier cannot be reached, the result is UNVERIFIED and no grade is shown. A verdict is a check against the evidence readable at call time, not a certification of safety.
The paid doors
The check above is the free basic tier. The full menu runs over x402 at flow-kg4x.vercel.app — prices printed before any sale, the same for everyone:
- PayCheck — $0.50 USDC. Before you pay this agent, check. One call grades a payee before payment: payee kind and history, address-poisoning look-alike detection, wallet approval exposure, contract safety, and recent settlement history — one finished grade with the evidence under it.
- Scope Report — $25 USDC. The full authorization scope of a Base wallet: enumerated ERC-20 allowances, EIP-7702 delegation status, Permit2 allowances, and the worst-case outflow derived two ways. Evidence fields and counts only — no composite score.
- Full-Surface Audit — $500 USDC. Flow's audit machinery turned on your own surface: claims frozen byte-exact, recomputed from source, graded leg by leg. No promised grade; a grade is what the evidence supports, published with its recompute.
Free, forever

Every sale splits 20 / 50 / 30: 20% back to the buyer, 50% Flow keeps, 30% to the Uplift Fund for the Flow network and its users.
