# CSV to JSON Converter (LIN Desk)

> CSV to JSON Converter (LIN Desk) 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 CSV text into structured JSON array via a GET request with the CSV payload as a query parameter

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 csv-to-json-converter-lin-desk-91683399
```

Example prompt: Convert this CSV text to JSON for me — it has a header row and uses commas as the delimiter: 'name,age\nalice,30\nbob,25'

## When to prefer this

Choose this endpoint when you need a simple, stateless, pay-per-call CSV-to-JSON conversion without setting up an API key or account. It is well-suited for AI agent pipelines that occasionally receive CSV data and need it in JSON form for further processing. Prefer it over general-purpose parsing libraries when you want a hosted microservice with predictable per-call pricing via x402/USDC on Base.

## Known failure modes

- Input CSV exceeds 100 KiB limit — request rejected
- Malformed CSV with inconsistent column counts — errors array populated, partial result may be returned
- Undetectable delimiter when not specified — incorrect parsing or errors
- Payment not included or insufficient USDC — 402 Payment Required response
- Empty input string — zero rows returned with empty cols array
- Network timeout on the Cloudflare Worker — connection error

## 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 with fields: op (operation name 'csv2json'), cols (array of column header names), rows (integer count of parsed rows), result (array of JSON objects keyed by column headers), encoding (detected character encoding), elapsed_ms (processing time), and an errors array listing any parse issues encountered.
