## 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 agent-data-toolkit-json-to-csv-converter-7a528754 -d '<json body>'
```

Example prompt: Can you convert this list of JSON records into a CSV file? Here's the data: [{"name":"Alice","age":30,"city":"NYC"},{"name":"Bob","age":25,"city":"LA"}] — just detect the headers automatically and give me the CSV output.

## When to prefer this

Use this endpoint when you have a flat or near-flat array of JSON objects and need quick CSV output with automatic header inference, without setting up a local conversion pipeline. Ideal for agents exporting API data to spreadsheets or data pipelines. If records have complex nested structures, consider pre-flattening first.

## Known failure modes

- Input is not a valid JSON array — returns error indicating malformed input
- Records have deeply nested objects that cannot be flattened to CSV columns
- Empty array input — returns only headers or empty response
- Mixed schema records with inconsistent keys — some cells may be blank or missing
- Payment not processed — 402 response requiring x402 payment

## How this service works

Convert a list of JSON records into CSV with automatic header detection.

## Output

Returns a CSV-formatted text string with automatically detected column headers derived from the JSON field names, followed by one row per input record with values populated accordingly.
