## 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 agent402-tools-json-to-csv-converter-d94102e9 -d '<json body>'
```

Example prompt: Convert this JSON array to CSV for me — it has nested objects I need flattened into dot-path columns: [{"name":"Alice","address":{"city":"NYC","zip":"10001"}},{"name":"Bob","address":{"city":"LA","zip":"90001"}}] — use a comma delimiter.

## When to prefer this

Use this endpoint when you have a JSON array of objects — possibly with nested sub-objects — and need a flat CSV representation suitable for spreadsheets or downstream data pipelines, especially when dot-path flattening of nested keys is desired.

## Known failure modes

- Invalid or non-array JSON input returns an error
- Malformed JSON string fails to parse
- Deeply nested or circular references may cause unexpected column naming
- Empty array input returns only headers or an empty response
- Delimiter value not accepted if multi-character or special character

## How this service works

Convert a JSON array of objects to CSV. Nested objects are flattened to dot-path columns.

## Output

Returns a CSV-formatted string with headers derived from the JSON object keys (nested keys expressed as dot-path columns like 'address.city'), and one row per object in the input array.
