Tools of Flow — Base quotes & contract safety for agents
	Description		Read-only	Idempotent	Open world
`flow_health`Check the Flow quote API health: status, chain, and latest synced block number.	Check the Flow quote API health: status, chain, and latest synced block number.	Not declared	Not declared	Not declared	Not declared
`flow_paycheck`Before you pay this agent, check. PayCheck ($0.50 USDC via x402 on Base) runs Flow's whole checker stack on a payee in ONE call — the payee verdict (kind, on-chain activity, the full contract-safety engine when the payee is a contract), the wallet approval-exposure audit, contract safety, and the payee's recent USDC settlement history — and returns one finished grade (ALLOW / REVIEW / BLOCK with a 0-100 score), a verify_status (verified / failed / unverified_verifier_down), every check, the evidence under it, and a receipt. The guarantee: the report is produced before settlement; if it cannot be produced, the payment is never settled — no report, no charge. This hosted endpoint does not hold a wallet: an unpaid call returns the endpoint's x402 payment challenge itself, never an invented result. Pay it with any x402 client, or use the @flowexecutor/flow-mcp stdio package with an Early Builder Key.	Before you pay this agent, check.

`flow_quote`Get a best-execution swap quote on Base. Compares Uniswap V3, PancakeSwap V3 and Aerodrome (plus two-hop routes via WETH), returns the winning venue, expected output, edge in bps vs the baseline, a liquidity flag (deep/watch/thin), the exact block number and timestamp, and build latency. Read-only: no funds move.	Get a best-execution swap quote on Base.

`flow_search`Verified Search ($0.01 USDC via x402 on Base): web search where every result is independently checked by Flow before it reaches you — the result URL is fetched live (liveness, final HTTP status recorded) and the fetched page text is matched against the result's own title/snippet terms (content-match score). Each result carries a verify_status (verified / failed / unverified_verifier_down), its httpStatus and contentMatch, and the response carries a receipt counting checked / verified / failed. Bad results are flagged, never silently dropped. The guarantee: the search is produced before settlement; if it cannot be produced, the payment is never settled.
