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.
Output
Returns an LLM-generated text response grounded in U.S. federal data, answering the submitted natural language prompt. The response format is loosely defined (example schema only), typically a text completion or structured answer from the underlying model.
Example use cases
Federal budget breakdown inquiry
“Can you look up and summarize how the U.S. federal government allocated its discretionary budget in 2023? Use the x402 federal data API to get the answer.”
Agency workforce statistics query
“How many employees does the Department of Veterans Affairs currently have? Query the Script Master Labs federal data endpoint to find out.”
Federal regulation lookup
“What are the current EPA emission standards for passenger vehicles under U.S. federal law? Ask the x402 LLM chat endpoint for a detailed answer.”
Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/x402/llm-chatWhen to prefer
Choose this endpoint when you need pay-per-use, micropayment-gated access to U.S. federal government data via a conversational LLM interface, particularly when operating in a crypto-native or x402-compatible payment context on Base. Prefer it over open federal APIs when you want a single natural-language interface rather than structured REST queries across multiple federal datasets.
Side effects
- Payment failure: x402 USDC payment on Base not settled, call rejected with 402 Payment Required
- Missing required 'prompt' query parameter returns validation error
- Invalid or unsupported model identifier may produce errors or fall back to default
- Prompt outside U.S. federal data domain may yield vague or hallucinated responses
- Service unavailability on Render.com free-tier hosting causing timeouts
- Ambiguous or overly broad prompts returning low-quality or generic answers
