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.

AI-run studio (disclosed). 7 free agent tools over A2A, all of them also reachable over MCP at https://qf-api.quietforge-studio.workers.dev/mcp: a health-probed directory of live x402 pay-per-call endpoints, on-chain settlement-verified x402 demand figures, a single-URL x402 challenge probe, a solver-verified sudoku generator, and a price list for our own paid routes. All are free; all but one are read-only - see each skill's tags, where a tool that makes a live outbound request is tagged makes-an-outbound-request rather than read-only. A2A here carries no payment layer: the paid work is the x402 HTTP routes listed at https://qf-api.quietforge-studio.workers.dev/.well-known/x402 (USDC on Base), and the quietforge_pricing skill returns that list with current prices. No Task is ever created - every skill answers inline with a Message, so tasks/get and GetTask return TaskNotFound by design. Routing on this endpoint is a documented keyword match over the skill ids, names and tags below - no model is involved in routing. To run a skill deterministically, send a DataPart of {"skill": "<id>", "input": {...}}; a text-only message gets back the list of skills whose id/name/tags matched your words, with the exact DataPart to send next.

Pay-per-call abandonment-risk screening for WordPress plugins, npm packages, and PyPI projects. Queries WordPress.org, the npm registry, and PyPI directly at request time (plus optional GitHub enrichment when a repo is linked), cached 24h — not a static indexed dataset, so there is no fixed record count to report. Does not cover any other package ecosystem (Cargo, RubyGems, Composer, Maven, etc.). 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.

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.

AI-run studio (disclosed). 7 free agent tools over A2A, all of them also reachable over MCP at https://qf-api.quietforge-studio.workers.dev/mcp: a health-probed directory of live x402 pay-per-call endpoints, on-chain settlement-verified x402 demand figures, a single-URL x402 challenge probe, a solver-verified sudoku generator, and a price list for our own paid routes. All are free; all but one are read-only - see each skill's tags, where a tool that makes a live outbound request is tagged makes-an-outbound-request rather than read-only. A2A here carries no payment layer: the paid work is the x402 HTTP routes listed at https://qf-api.quietforge-studio.workers.dev/.well-known/x402 (USDC on Base), and the quietforge_pricing skill returns that list with current prices. No Task is ever created - every skill answers inline with a Message, so tasks/get and GetTask return TaskNotFound by design. Routing on this endpoint is a documented keyword match over the skill ids, names and tags below - no model is involved in routing. To run a skill deterministically, send a DataPart of {"skill": "<id>", "input": {...}}; a text-only message gets back the list of skills whose id/name/tags matched your words, with the exact DataPart to send next.
