Agent data quality · data-quality
Heuristic content-type sniff from sample bytes or filename. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Honest limit: execution uses only caller-supplied data in memory; it does not call a paid upstream, retain input, search the web, read a live RPC, or invoke a media generator. Results are advisory; the caller owns authorization, budgets, and production controls.
One-command purchase
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
