# Proofwork CSV to JSON Converter

> Proofwork CSV to JSON Converter is a paid API for AI agents from proofwork-the402-webhook.phase-voice.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).

Converts URL-encoded CSV text (with a header row) into structured JSON rows, column metadata, and row count via a pay-per-request x402 API on Base.

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 proofwork-csv-to-json-converter-b984f80b
```

Example prompt: Can you convert this CSV text to JSON for me? The CSV has a header row: 'id,name,city\n1,Ada,London\n2,Grace,Chicago'

## When to prefer this

Use this endpoint when you need a quick, lightweight, pay-per-use CSV-to-JSON conversion without standing up your own parser — especially useful in agent workflows where tabular data arrives as raw CSV text and needs to be restructured as JSON for downstream processing. It is a good fit for small-to-medium CSV payloads passed inline as query parameters.

## Known failure modes

- Missing or malformed 'csv' query parameter returns an error
- CSV without a header row may produce unexpected key names or fail
- URL-encoding issues with special characters may corrupt the CSV input
- Payment failure via x402 on Base will block the request
- Extremely large CSV payloads may exceed query parameter size limits

## How this service works

Small non-cyber evidence and data APIs payable per request with x402 on Base.

## Output

Returns a JSON object containing an array of row objects (each CSV row as a key-value map using header names as keys), a list of column names, a total row count, a report type identifier ('csv_to_json'), and a content type field ('application/json').
