## 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`):

Example prompt: Can you convert this JSON data into a CSV file for me? Here's the content: '[{"name":"Alice","age":30,"city":"NYC"},{"name":"Bob","age":25,"city":"LA"}]' — I need it in CSV so I can open it in Excel.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.0005 USDC), serverless JSON-to-CSV conversion without setting up local tooling. Ideal for agents automating data pipelines that need to export JSON API responses into spreadsheet-compatible formats. Prefer this over generic file conversion services when input is specifically JSON and output must be standard CSV.

## Known failure modes

- Invalid or malformed JSON input returns an error response
- Nested/complex JSON objects may not flatten cleanly into tabular CSV rows
- Empty JSON array may return an empty CSV with no rows
- Missing 'content' field in request body causes a validation error
- Deeply nested JSON structures may lose hierarchy information in flat CSV output

## How this service works

Document and data format conversions via Pandoc, Chromium-headless, and pure-JS libs. Text inputs/outputs are JSON-fielded; binary inputs/outputs use base64 in JSON for uniformity.

## Output

A JSON object containing the converted CSV text, where JSON array records become CSV rows with headers derived from JSON keys, suitable for import into spreadsheet tools or further processing.
