## 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 gocreative-treasury-rates-api-8c8d548a
```

Example prompt: What are the current U.S. Treasury interest rates across all maturities — I need the full yield curve from T-bills through 30-year bonds?

## When to prefer this

Use this endpoint when you need authoritative, up-to-date U.S. Treasury interest rate data across multiple maturities for financial modeling, risk-free rate benchmarks, yield curve analysis, or macroeconomic research. Prefer this over general finance APIs when you specifically need official Treasury yields without requiring an API key or signup.

## Known failure modes

- Treasury data source temporarily unavailable — service may return 503 or empty data
- Payment not processed (insufficient USDC balance) — returns 402 Payment Required
- Data not yet published for today if queried early in the trading day
- Invalid format parameter returns default format or error

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output
