## 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-search-450b770e -d '<json body>'
```

Example prompt: Can you search the US Census Bureau for population and demographic data using this census URL: https://api.census.gov/data/2020/dec/pl?get=P1_001N&for=state:06

## When to prefer this

Use this endpoint when you need to retrieve US Census Bureau data programmatically without managing Census API credentials yourself, and when pay-per-call micropayment pricing via x402/USDC is acceptable. Prefer this over direct Census API calls when operating in an agent context that already handles x402 payments.

## Known failure modes

- Invalid or malformed census URL returns an error
- Census Bureau API endpoint unavailable causes timeout or failure
- URL pointing to non-Census domain may be rejected or return unexpected results
- Missing required 'url' field in request body returns validation error
- Rate limiting from Census Bureau upstream may cause failures

## How this service works

Pay-per-call web and onchain utilities for AI agents (MPP + x402, USDC on Base).

## Output
