# JSON to CSV Converter

> JSON to CSV Converter is a paid API for AI agents from lin-desk-x402.lindesk.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Converts JSON (or other structured data formats) into CSV text with configurable delimiter, returning column names, row count, and the CSV result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-83b30bdb
```

Example prompt: Take this JSON array — [{"name":"alice","age":30},{"name":"bob","age":25}] — and convert it to CSV with comma as the delimiter.

## When to prefer this

Use this endpoint when you need a fast, pay-per-call, no-signup conversion of JSON (or other structured formats) to CSV text — particularly in agentic workflows where you want to avoid managing API keys or subscriptions. Ideal for one-off data pipeline steps, agent-driven ETL tasks, or when preparing JSON API responses for spreadsheet consumption.

## Known failure modes

- Input payload exceeds 100 KiB limit — request rejected
- Malformed or non-parseable JSON/CSV/YAML/XML input — errors array populated in response
- Missing required 'input' query parameter — bad request error
- Payment not provided or insufficient USDC — 402 Payment Required response
- Deeply nested JSON that cannot be flattened to tabular CSV — partial or empty result

## How this service works

Pay-per-call API for AI agents: turn any public web page or PDF into clean, LLM-ready Markdown. $0.002 per call in USDC on Base via x402. No API key, no signup.

## Output

Returns a JSON object containing the operation name ('json2csv'), an array of column names, the number of rows converted, the resulting CSV text as a string, elapsed processing time in milliseconds, and any validation errors encountered.
