## 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-price-changes-1d44b7e5 -d '<json body>'
```

Example prompt: Can you pull the price change data from this Census Bureau URL for me: https://www.census.gov/data/tables/time-series/econ/price-changes/2024.html

## When to prefer this

Use this endpoint when you need to programmatically extract price change or economic index data from a specific Census Bureau or similar government data URL, especially in an agentic workflow where you want to pay per call with USDC on Base via x402 without managing subscriptions.

## Known failure modes

- Invalid or inaccessible URL returns an error
- URL does not contain census price change data — may return empty or malformed response
- Rate limiting or timeout if the target URL is slow to respond
- Non-Census or unrecognized URL formats may yield unexpected output
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee

## How this service works

## Output

Returns structured price change data extracted from the provided URL, likely including percentage changes, time periods, commodity or sector categories, and index values as published by the referenced source.
