## How to call it through Zero

```sh
zero fetch --capability econ-memoryapi-org-b7202383
```

Example prompt: Can you pull the Census demographic data for Travis County, Texas — I want population, median household income, poverty rate, and median home value?

## When to prefer this

Use this endpoint when you need granular U.S. demographic data at the state or county level, especially for socioeconomic indicators sourced from the Census Bureau. Prefer this over general FRED macroeconomic endpoints when the query is about local/regional population, poverty, education, or housing characteristics rather than national-level macro trends.

## Known failure modes

- Invalid or unrecognized state/county name returns an error
- County not found if input is ambiguous or misspelled
- Payment failure if USDC balance is insufficient for the $0.001 fee
- Rate limiting if too many requests are sent in quick succession
- Data may lag behind real-time conditions as Census data is periodically updated
