## 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-90322cb0 -d '<json body>'
```

Example prompt: Convert this JSON array to CSV for me: [{"name":"Alice","age":30,"city":"New York"},{"name":"Bob","age":25,"city":"London"}]

## When to prefer this

Use this endpoint when you have a JSON array of flat or semi-flat objects and need to produce CSV output quickly without setting up a local parser. Ideal for agents that receive JSON from upstream APIs and need to pass tabular data to downstream tools, spreadsheet applications, or bulk-import systems that only accept CSV. Prefer this over a local conversion when operating in a stateless pipeline and the $0.01 per-call cost is acceptable.

## Known failure modes

- Input is not a valid JSON array — returns an error if the string is malformed JSON or is a JSON object instead of an array
- Input array contains heterogeneous objects with inconsistent keys — may produce misaligned columns or missing values
- Empty array input — may return only headers or an empty response
- Non-serializable values (nested objects, arrays) may be stringified or dropped rather than flattened

## How this service works

Convert a JSON array of objects to CSV

## Output

Returns a CSV-formatted text string where the first row contains column headers derived from the JSON object keys, and each subsequent row represents one object from the input array with values in the corresponding columns.
