## 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 csv-header-extractor-0f6c4e51 -d '<json body>'
```

Example prompt: Can you pull out the column headers from this CSV data I have? Here's the content: 'name,age,email\nAlice,30,alice@example.com\nBob,25,bob@example.com'

## When to prefer this

Use this endpoint when you need a quick, pay-per-use, agent-friendly extraction of CSV column names without setting up a local parser. Ideal for autonomous agents operating in x402 micropayment environments that need lightweight CSV introspection on demand.

## Known failure modes

- Malformed or empty CSV input may return an error or empty result
- Missing 'value' field in request body returns a validation error
- Non-CSV content passed as input may produce unexpected or empty headers
- Network timeout on the Render-hosted service during cold starts
- Payment failure via x402 protocol results in 402 response before processing

## How this service works

Machine-callable x402-paid utilities for autonomous agents.
