## 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 orchard-data-treasury-yields-59364147
```

Example prompt: What are the current US 10-year and 30-year Treasury yields and how much have they changed today?

## When to prefer this

Choose this endpoint when you need real-time US Treasury yield data (10-year, 30-year) with per-call micropayment billing via USDC on Base (x402 protocol), especially in autonomous agent workflows that require pay-as-you-go access without API key subscriptions.

## Known failure modes

- 402 Payment Required if no valid x402 USDC payment header is provided
- Stale or missing data if upstream market feed is delayed
- Empty or partial array if specific yield labels are unavailable
- Network timeout on the Cloudflare Workers edge runtime
