How this service works
Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/x402/entity-complianceWhen to prefer
Use this endpoint when you need to verify whether a U.S. entity is compliant and eligible for federal contracts or grants, using their UEI or CAGE code. Prefer this over general business lookup APIs when the context is specifically federal procurement, SAM.gov registration, or contractor vetting. The pay-per-call x402 model makes it suitable for on-demand, low-volume compliance checks without a subscription.
Side effects
- UEI or CAGE code not found in federal database — returns 404 or empty result
- Invalid or malformed UEI/CAGE format — returns validation error
- Payment not settled — x402 payment failure prevents data delivery
- Upstream federal data source unavailable — returns 503 or timeout
- Missing both UEI and CAGE — returns 400 bad request
