Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/x402/firms?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover U.S. federal contractor firms by industry (NAICS code) and optionally narrow by state or set-aside program type (e.g., 8a, HUBZone, WOSB). Prefer this over general web search when you need structured, filterable procurement data with micropayment-based access.

- Payment not settled via x402 returns a 402 Payment Required response
