## 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 adh-processed-us-treasury-yield-curve-signal-f44c7eff
```

Example prompt: What is the current US Treasury yield curve doing — give me the 10-year yield, the 2s10s spread, and whether we're in an inverted or normal curve regime right now?

## When to prefer this

Choose this endpoint when you need a pre-interpreted, agent-ready US yield curve signal rather than raw bond data — it combines yield levels, spread math, fed funds context, and a plain-language macro conclusion in one call, saving the agent from multi-source aggregation and interpretation steps. Prefer it over raw data APIs when your agent needs to reason about macro regime (soft landing vs recession risk) without additional processing.

## Known failure modes

- Stale data if upstream sources are delayed — check collected_at timestamp
- Payment failure via x402 if USDC balance is insufficient or facilitator is unavailable
- Empty or partial response if data pipeline has not refreshed since last collection window
- Rate limiting or access denial if x402 payment header is malformed

## Output

A JSON object containing: current US 10-year Treasury yield (%), 2s10s spread (basis points), fed funds rate (%), a labeled curve state (e.g. 'normal/steepening' or 'inverted'), a natural-language interpretation of what the curve implies for growth and risk assets, a timestamp, and a short historical series of recent yield snapshots for trend context.
