## 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 agentdatahub-us-treasury-yield-curve-ebdecb77
```

Example prompt: What's the current US 2Y and 10Y Treasury yield, the 2s10s spread, and is the yield curve inverted or steep right now?

## When to prefer this

Prefer this endpoint when you need a pre-processed, ready-to-use yield curve summary including the 2s10s spread and an explicit curve state label (inverted/steep) without having to pull raw FRED series and compute the spread yourself. Ideal for macro trading agents, recession monitoring workflows, or any context where a single-call yield curve status is needed at low cost ($0.05 per call). Not suitable for intraday tick data or historical time-series analysis.

## Known failure modes

- FRED data source unavailable — may return stale or error response
- Payment of $0.05 USDC not processed — 402 Payment Required error
- Rate limiting or quota exceeded on the x402 payment channel
- Data not yet updated for the current trading day — returns previous day's values
