## 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 red-web-utils-census-stats-f2abdd17 -d '<json body>'
```

Example prompt: Can you pull census statistics for Travis County, Texas — I need population and demographic data from the Census Bureau?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to U.S. Census Bureau statistics without managing Census API keys directly. It is ideal for AI agents that need lightweight, on-demand demographic lookups billed in USDC micro-payments via x402 protocol. Prefer alternatives (direct Census API) for high-volume batch queries where per-call cost would accumulate.

## Known failure modes

- Invalid or malformed URL input returns a 400 error
- Census endpoint not found or unavailable returns a 404 or empty response
- Payment not received or insufficient USDC balance triggers a 402 Payment Required response
- Rate limiting or upstream Census Bureau API downtime may cause timeouts
- Unsupported geographic entity or census table returns empty or error response

## How this service works
