How this service works
Pay-per-call tools for AI agents: any document to clean Markdown (PDF, Word, Excel, PowerPoint, web pages); US company fundamentals, SEC filings and insider trades; Treasury yields; FRED macro data; official FX rates (ECB, Bank of Russia); hash, base64, JWT, UUID and JSON utilities. x402 USDC micropayments, no account or API key. Charged only on success.
Output
A JSON object with the curve date, yields in percent for standard tenors (3M, 2Y, 10Y, 30Y, etc.), spread metrics in basis points (e.g. 10Y-2Y), and optionally an array of historical daily yield points for a single requested tenor over up to 250 days.
Example use cases
Macro dashboard yield curve snapshot
“What does the US Treasury yield curve look like today — give me rates for 3M, 2Y, 10Y, and 30Y, plus the 10Y-2Y spread.”
Historical rate trend analysis
“Get me the daily 10-year Treasury yield for the last 180 days so I can see how it's trended since the Fed's last decision.”
Point-in-time yield curve lookup
“What did the US Treasury yield curve look like on March 15, 2024? I need the full curve for that specific date.”

Ideal for macro analysis, fixed-income context, or agent workflows that need real-time or historical risk-free rate benchmarks paid via USDC micropayment per call.
Side effects
- Date not yet available (Treasury data has a 1-day lag) — returns error or empty curve
- Invalid tenor string (e.g. unsupported maturity code) — validation error
- history_days exceeds 250 — rejected with validation error
- Weekend or holiday date with no published data — may return nearest available or error
- Payment failure via x402 — 402 response, no data returned
