# Wealth Agent CSV↔JSON Converter

> Wealth Agent CSV↔JSON Converter is a paid API for AI agents from wealth-agent.wealthagent-app.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-19).

Converts CSV/TSV text to JSON or JSON arrays to CSV format via a paid API endpoint

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 wealth-agent-csv-json-converter-a09db354
```

Example prompt: Convert this CSV text into a JSON array: 'name,price\nApple,1.50\nBanana,0.75'

## When to prefer this

Choose this endpoint when you need a simple, paid-per-call microservice to convert between CSV/TSV and JSON without setting up your own parsing logic. It is well-suited for agent workflows that occasionally need tabular data reformatting as part of a larger pipeline, especially when the x402 micropayment model is already in use. Prefer a local library if you are doing high-volume batch conversions where per-call costs would accumulate significantly.

## Known failure modes

- Malformed or unparseable CSV/TSV input returns an error field in the response
- Missing required 'data' query parameter causes a validation error
- Mismatched or ambiguous format when 'to' is omitted may result in incorrect direction inference
- Payment failure or insufficient USDC balance causes a 402 response before processing begins
- Empty data input may return zero rows with no useful output

## How this service works

Convert tabular data between CSV/TSV and a JSON array of objects, in either direction, with detected delimiter and typed columns. Use it when a tool returns CSV but your pipeline needs JSON (or the reverse) and you do not want to run a parser yourself.

## Output

Returns a JSON object containing the converted data (a JSON array when converting from CSV, or CSV text when converting from JSON), along with metadata including the kind of conversion performed ('csv-json'), the number of rows, the column names, and the direction of conversion.
