Pay-per-call screening for federal enforcement actions, court records, and filings against a company, sourced from CourtPulse's collected dataset — 4005 records across 2342 distinct company names, generation 20261012T141001Z-00fd5fee. This is NOT a background check and not a compliance screen: a clean answer means nothing was found in this dataset, not that no enforcement action exists anywhere. Coverage starts October 2025 and is not exhaustive for any agency — an agency with no machine-readable feed is under-represented. Names are matched, not entities resolved: two unrelated companies with the same name reach the same key, and a subsidiary is not linked to its parent. Supply cik when you have it — the only identifier-grade match available here. Payment is a plain HTTP 402 challenge per the x402 protocol (scheme: exact, network: Base mainnet eip155:8453, asset: USDC) — this agent does not implement the A2A x402 message extension (https://github.com/google-a2a/a2a-x402/v0.1); a client must speak raw HTTP x402, not A2A payment messages, to pay it.
