## 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-delx-ai-a089926f -d '<json body>'
```

Example prompt: Take these JSON rows and convert them into a CSV file I can open in Excel: [{"name":"Alice","age":30,"city":"Boston"},{"name":"Bob","age":25,"city":"Denver"}].

## When to prefer this

Use this endpoint when you have structured JSON data (array of objects) and need a CSV representation for spreadsheet use, data export pipelines, or downstream handoff to non-technical stakeholders. Ideal for AI agents completing ETL steps, generating downloadable reports, or preparing data for tools like Excel or Google Sheets.

## Known failure modes

- Malformed or non-array JSON input returns a validation error
- Empty JSON array may return empty CSV with headers only
- Deeply nested JSON objects may not flatten correctly
- Missing or inconsistent keys across rows may result in misaligned columns
- Request timeout on very large payloads

## How this service works

## Output

Returns CSV-formatted text derived from the input JSON rows, with headers inferred from the JSON object keys and each row serialized as a comma-separated line, ready for file download, spreadsheet import, or further processing.
