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
A structured response containing U.S. Treasury yield rates across maturities (e.g. 1-month, 3-month, 6-month, 1-year, 2-year, 5-year, 10-year, 30-year) for the requested month, sourced from U.S. federal data and returned after a $0.05 USDC micropayment settled on Base via x402.
Example use cases
Monthly yield curve snapshot
“Can you grab the full Treasury yield curve for January 2024? I need rates across all maturities for that month to update my financial model.”
Risk-free rate for valuation
“What's the current 10-year Treasury yield? I need the risk-free rate to plug into my discounted cash flow analysis.”
Compare T-bill yields over time
“Pull the 3-month and 6-month T-bill yields for both March 2024 and June 2024 so I can compare how short-term rates shifted over that period.”
Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/x402/treasury-yieldsWhen to prefer
Choose this endpoint when you need pay-per-call U.S. Treasury yield data without a subscription and can settle micropayments in USDC on Base via x402. Ideal for agents with x402 payment capability needing ad-hoc yield curve lookups rather than a bulk data subscription. Prefer over free alternatives when programmatic micropayment settlement is already wired into the agent workflow.
Side effects
- Payment failure — insufficient USDC balance or x402 payment not accepted (402 Payment Required)
- Invalid month format — non-ISO date string causes 400 Bad Request
- Month out of range — future or very old months may return no data or 404
- Service unavailable — hosted on Render free tier, may cold-start or be offline (503)
- No data for requested month — Treasury data not yet published for the given period
