| Tool | Description | Behaviour |
|---|---|---|
| buy_contract_data | Paid over x402 in USDC on Base, from 0.0049 per call. Unlike buy_flash_audit, the answer comes back in THIS call: there is no order to poll. Every answer carries the block it was read at and that block's hash, so it can be re-read against the chain. Call contract_data_catalog first for the list and prices. Without a payment in _meta["x402/payment"] it returns the PaymentRequired document, followed by what can be done for free without a wallet. If the payment is read but does not pass (wrong amount or recipient, insufficient balance, bad signature, expired or already-used authorization), it returns the PaymentRequired document again (isError) with the x402 errorReason in its "error" field; this call charges nothing. | Changes data |
| buy_flash_audit | Paid over x402 in USDC on Base. Without a payment in _meta["x402/payment"] it returns the PaymentRequired document (isError), followed by how a person without a wallet can buy the same report in the web store. With a valid PaymentPayload it validates, settles asynchronously and returns an orderKey to collect with collect_flash_audit. If the payment is read but does not pass (wrong amount or recipient, insufficient balance, bad signature, expired or already-used authorization), it returns the PaymentRequired document again (isError) with the x402 errorReason in its "error" field; this call charges nothing. | Changes data |
| check_contract_free | Free, no wallet. Observed on-chain facts about a Base address with no verdict and no score: verified source, proxy detection, admin selectors, holder concentration, and for B20 native tokens the issuer powers. Rate limited; a monthly quota applies. | Read-only |
| collect_flash_audit | Status of an x402 order while it settles and generates; once DELIVERED, the report JSON itself. Poll every 10-15 seconds. Free. | Read-only |
| contract_data_catalog | Free, no wallet. Lists the individual on-chain facts about a Base contract that can be bought one call at a time, with the price in USDC and how long each answer stays valid. Read this before paying: the bundle costs less than buying the parts. | Read-only |
| flash_audit_terms | Returns the x402 v2 PaymentRequired document for the paid Flash Report: amount in USDC base units, network, asset, payTo and the request schema. Free. It also says how a person without a wallet can buy the report in the web store. | Read-only |
