## 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 agentrxi-us-demographics-by-zip-code-0f009ce3
```

Example prompt: Pull up the Census ACS demographics for ZIP code 30301 — I need population, median household income, median age, home value, and poverty rate.

## When to prefer this

Choose this endpoint when you need quick, structured Census ACS demographic data for a specific US ZIP code without building a Census API integration yourself. Ideal for real estate analysis, market research, lead scoring, social services targeting, or any workflow that needs socioeconomic context tied to a US postal code. Prefer this over raw Census API access when simplicity, pay-per-call pricing, and agent-friendly JSON output are priorities.

## Known failure modes

- Invalid or non-existent ZIP code returns an error or empty result
- ZIP codes in US territories or PO-box-only ZIPs may have incomplete or missing Census data
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many requests are made in a short period
- Census data may be 1-3 years behind current conditions due to ACS 5-year survey cadence
