curl -i -X POST https://edgar-mcp.mtree.workers.dev/v1/filings/search \

# then retry with X-PAYMENT header. The response is the actual data.EDGAR is the canonical, source-of-truth record of every U.S. public-company filing — but its search UI is human-only and the underlying APIs require respecting SEC's fair-access User-Agent policy plus stitching three different upstreams together (full-text index, submissions JSON, and the Archives raw documents). This service is the x402-native door: agents pay USDC for what they need, no human onboarding, no API key, no minimum.
