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).

Endpoint
POSThttps://mcp-x402-discovery.onrender.com/x402/chat/completionsWhen to prefer
Choose this endpoint when you need pay-per-call access to specialized niche datasets — SEC filings, HUD/Section 8 housing data, crypto gas metrics, and federal compliance data — through a conversational chat interface, and you want to pay per query using USDC micropayments via x402 rather than maintaining a subscription. Ideal for agents that need occasional, targeted lookups across these specific domains without committing to a flat-rate API plan.
