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.

Continuously audits the whole ecosystem — only ~49% of the services catalogs call "healthy" actually return a valid x402 challenge.

Verify before you pay or install. **Before you pay an x402 endpoint** — liveness, a 0–100 trust score, scam flags (payTo hijack, bait-and-switch pricing, honeypot receiver) and a pay/avoid verdict, with on-chain proof links on Base. **Before you trust an MCP server or npm package** — what changed *after* people adopted it: install script added in a later version, ownership swapped, repository removed, package unpublished, build provenance lost. Static scanners answer whether a package is safe today. This answers the other question, and it needs yesterday's snapshot to exist. PulseFeed diffs the entire MCP registry against the previous day's snapshot every night, and re-probes the x402 endpoint population daily. The series runs from 2026-07-30 and cannot be reconstructed after the fact.

**Pay-per-call API marketplace on Base (USDC).** x402-market lets AI agents discover and invoke any listed API end-to-end with one tool call. The MCP server handles HTTP 402 payment challenges automatically using your wallet, so Claude (or any MCP client) pays for API calls on its own. ## How it works 1. `list_catalog` — discover available paid APIs in the marketplace 2. `get_listing` — inspect endpoint schema, pricing, and usage notes 3. `pay_and_call` — invoke the API end-to-end; pays the seller via x402 / USDC on Base if a 402 challenge is returned 4. `claim_refund` — auto-judge refund for failed calls or >30s upstream latency ## Setup - `MCP_BUYER_PRIVATE_KEY` (required): Hot wallet on Base mainnet with a small USDC + ETH balance. **Use a separate wallet, not your main one.** - `MCP_MAX_PRICE`: Hard cap per call (USDC). Default `1`. - Other params have safe defaults. ## Links - npm: `@x402-market/mcp-server` - GitHub: https://github.com/AsaiShota/x402-market - Marketplace API: https://x402-market-api.lien-studio-akiyama.workers.dev
