## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability docparse-treasury-yields-b864ba5a -d '<json body>'
```

Example prompt: Pull today's full US Treasury yield curve and also give me the last 90 days of daily 10Y yield history so I can chart how rates have moved.

## When to prefer this

Use this endpoint when you need official US Treasury yield curve data, yield spreads, or historical rate series without setting up an account or API key. 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.

## Known failure modes

- 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

## 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.
