Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-csv-to-json-converter-eda1a732 -d '<json body>'
```

Example prompt: Can you convert this CSV data into JSON objects using the first row as headers and a semicolon as the delimiter? The CSV is: 'name;age;city\nAlice;30;New York\nBob;25;London'

## When to prefer this

Use this endpoint when you need reliable CSV-to-JSON parsing with quoted field support, custom delimiters (e.g. semicolon, tab), and optional header row control. Ideal for agents processing tabular data exports before further analysis or storage.

## Known failure modes

- CSV exceeds 100KB limit — request rejected
- Malformed CSV with unmatched quotes — parse error returned
- Invalid delimiter value — error or unexpected parsing behavior
- Empty CSV input — empty array returned
- Network or payment failure — 402 or 5xx error

## How this service works

Parse CSV (quoted fields supported) into a JSON array of objects, using the first row as headers (header=false for arrays).

## Output

A JSON array of objects where each row becomes an object with keys from the header row, or a JSON array of arrays if header=false. Quoted fields and custom delimiters are handled correctly.
