# Coinslot JSON↔CSV Converter

> Coinslot JSON↔CSV Converter is a paid API for AI agents from coinslot.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Converts an array of JSON objects to CSV (with nested keys flattened to dot-path column headers) or converts a CSV string back to an array of JSON objects.

## 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 coinslot-json-csv-converter-af768c2c -d '<json body>'
```

Example prompt: Convert this JSON array to CSV for me — the objects have nested fields like address.city and address.zip, so make sure those become dot-path columns: [{"name":"Alice","address":{"city":"NYC","zip":"10001"}},{"name":"Bob","address":{"city":"LA","zip":"90001"}}].

## When to prefer this

Choose this endpoint when you need a simple, stateless JSON↔CSV conversion that correctly handles nested object keys via dot-path flattening, without setting up a local library or runtime. Ideal for agents processing data pipelines, generating spreadsheet exports from API responses, or ingesting CSV uploads into JSON workflows.

## Known failure modes

- Invalid direction value (not 'json-to-csv' or 'csv-to-json') returns an error
- Malformed JSON array (not an array of objects) causes a parse error
- Malformed CSV string (inconsistent columns, unclosed quotes) causes a parse error
- Empty data input may return an empty result or error
- Deeply nested objects may produce very long dot-path column names

## How this service works

Convert an array of JSON objects to CSV (nested keys become dot-path columns) or CSV back to JSON. POST { direction: 'json-to-csv'|'csv-to-json', data }.

## Output

For json-to-csv: a CSV string where each JSON object becomes a row and nested keys are flattened to dot-path column headers (e.g. address.city). For csv-to-json: an array of JSON objects parsed from the CSV rows, with column headers as keys.
