x402 Pre-Payment Check

Before paying an unknown x402 endpoint, ask for a verdict. Checks the live 402 response without paying, compares the price with its market category, shows real usage from the Coinbase Bazaar (payers, repeat buyers, last payment) and the seller's footprint, and returns ok, caution or avoid with reasons.

Which paid API should an agent call for a task? Search the x402 market by keyword or category and get offers ranked by real repeat usage (payers, calls per payer, last payment, price) from a daily survey of the Coinbase Bazaar. Without a query it returns the category overview with demand figures. Helps agents pick services that others actually keep paying for.

Use before buying or approving an unknown ERC-20 token on Base. Rule-based check straight from the chain, without AI - contract and proxy (upgradeable?), owner and whether it was renounced, risky owner functions in the bytecode (mint, pause, blacklist, fees, trading switches), owner share of supply and DEX liquidity on Uniswap V2/V3 and Aerodrome in USD. Returns ok, caution or avoid with reasons in under two seconds. Technical check, not investment advice.

Use when an agent needs fresh web results for a question. Send a plain query and get up to 10 ranked results with title, URL, publish date and a short excerpt, ready to cite. Fast, no account and no API key on your side; pay per call with x402. Results come from a licensed search provider and are not cached across customers.

Use when an agent needs verified US investor data. funding_rounds returns recent private funding rounds from SEC Form D (issuer, amount raised, investors, industry, executives) by company, state, industry, date or size. company_facts returns fundamentals of a listed company (revenue, income, EPS, cash flow, assets, shares), latest annual and quarterly. Every value cites its SEC filing. No AI, pay per call.
