## 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 api-strale-io-3e5f882c
```

Example prompt: Convert this JSON array to CSV using a semicolon as the delimiter: [{"name":"Alice","age":30,"city":"Paris"},{"name":"Bob","age":25,"city":"Lyon"}]

## When to prefer this

Choose this endpoint when you need a pure, instant, cheap algorithmic conversion of a JSON array of objects to CSV with no external dependencies. Ideal for preparing API response data for spreadsheet download, data pipeline output, or human-readable tabular exports. Prefer this over general-purpose code-execution endpoints when the task is purely JSON-to-CSV formatting.

## Known failure modes

- Input array is empty — may return empty CSV or error
- Array elements have inconsistent keys — missing fields may produce blank columns
- Invalid JSON passed in data param — returns parse error
- Non-array value passed as data — schema validation error
- Unsupported delimiter characters may cause malformed CSV output

## How this service works

Convert a JSON array of objects to CSV format. Supports custom delimiters. Pure algorithmic — instant and cheap.

## Output

A CSV-formatted string with a header row derived from the JSON object keys and one data row per object in the input array, columns separated by the specified delimiter (default: comma).
