## 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 x402-convert-csv-json-820964a1 -d '<json body>'
```

Example prompt: Convert this CSV into a JSON array — it has a header row with columns name, age, city followed by a few rows of data.

## When to prefer this

Choose this endpoint when you need deterministic, stateless CSV↔JSON conversion billed per-call with no API key setup — ideal for AI agent workflows that handle tabular data and can pay micro-amounts in USDC on Base via x402.

## Known failure modes

- Malformed CSV without a header row may produce unexpected keys or an error
- JSON input that is not an array of flat objects may fail or produce incomplete CSV
- Missing or empty 'csv'/'json' field in the request body returns an error
- Payment failure or insufficient USDC balance blocks the request with a 402 response
- Very large payloads may hit Cloudflare Workers size limits

## How this service works

## Output

A JSON response containing either a 'json' key with an array of objects (one per CSV row, keyed by header names) when converting CSV→JSON, or a 'csv' key with a CSV string when converting JSON→CSV.
