## How to call it through Zero

```sh
zero fetch --capability api-lastlookdata-com-116dfb4a
```

Example prompt: Can you pull the latest mortgage market pulse — I need current 30yr and 15yr mortgage rates, the 10Y Treasury yield, Fed funds rate, MBS spread, median home price, and housing starts all in one shot?

## When to prefer this

Use this endpoint when you need a single-call snapshot of the entire US mortgage market — including rates, housing fundamentals, and rate trend — rather than querying individual FRED series separately. Ideal for mortgage market briefings, housing affordability analysis, or LLM context injection requiring multiple correlated indicators at once.

## Known failure modes

- Data source temporarily unavailable from FRED or upstream provider — may return 503 or stale data
- Payment of 0.4 USDC not fulfilled via x402 — returns 402 Payment Required
- Rate limiting or abuse detection — returns 429 Too Many Requests
- Unexpected schema change in upstream FRED data — partial or malformed response
