## 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 json-rows-to-csv-converter-6f49267f -d '<json body>'
```

Example prompt: Can you convert these JSON rows into a CSV? Here are the rows: [{"name":"Alice","age":30},{"name":"Bob","age":25}] and I want the columns in this order: name, age.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON-to-CSV conversion without standing up your own transformation logic — particularly useful in agentic workflows where you want structured tabular output from JSON data without managing server infrastructure. It is ideal when you already have JSON row arrays and a known column order and need clean CSV output fast.

## Known failure modes

- Missing or malformed 'rows' parameter returns an error response
- Column list mismatch with row keys may produce empty or incomplete columns
- Payment failure or insufficient funds results in HTTP 402 and no conversion
- Oversized row arrays may time out or be rejected
- Non-array rows input causes a schema validation error
