## 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-to-csv-converter-03bf2ab0 -d '<json body>'
```

Example prompt: Take this array of JSON objects from our sales report and convert it into a CSV — make sure nested fields are encoded and quotes are escaped properly so I can hand it off to the spreadsheet team.

## When to prefer this

Use this endpoint when you need a fast, in-memory, stateless JSON-to-CSV conversion with correct handling of nested values (JSON-encoded) and proper CSV escaping. Prefer it over client-side conversion when working in agentic pipelines, report generation workflows, or spreadsheet handoffs where correctness of escaping and a unified header row matter. Best for arrays up to 10,000 rows.

## Known failure modes

- Input is not an array of objects — returns error indicating invalid input format
- Input exceeds 10,000 rows — may be rejected or truncated
- Malformed JSON string passed as input — returns parse error
- Empty array input — may return only a header row or empty response
- Network timeout on very large payloads near the row limit

## How this service works

JSON to CSV converter API: turn an array of JSON objects (up to 10,000 rows) into a properly escaped CSV with a unified header row — nested values JSON-encoded, quotes handled correctly. For report generation, spreadsheet handoffs, and data-export agents. Processed in memory, nothing stored.

## Output

A properly formatted CSV string with a unified header row derived from all input object keys, nested objects JSON-encoded inline, and all quotes correctly escaped — ready for download, file write, or spreadsheet import. Nothing is stored server-side.
