## 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 agentshelf-csv-to-json-converter-a9139872 -d '<json body>'
```

Example prompt: Convert this CSV text into a JSON array of objects — the columns are separated by commas: 'name,age,city\nAlice,30,New York\nBob,25,London'

## When to prefer this

Prefer this endpoint when an agent needs a reliable, low-latency, server-side CSV-to-JSON conversion without executing local code. Especially useful when the CSV delimiter is non-standard (e.g. semicolon or tab). Use the free sandbox endpoint POST /v1/sandbox/csv-to-json first if available; fall back to this paid endpoint when the sandbox is unavailable or rate-limited.

## Known failure modes

- Empty or missing 'csv' field returns a validation error
- CSV string exceeds 100,000 character limit causing rejection
- Malformed CSV with inconsistent column counts may produce unexpected output
- Invalid or multi-character delimiter value causes schema validation failure
- Payment of exactly $0.002 USDC not provided triggers x402 payment required response

## How this service works

Call when an agent needs a CSV table converted to a JSON array of objects. No network. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/csv-to-json first.

## Output

A JSON array of objects where each element corresponds to a CSV row, with keys derived from the header row and values from each subsequent row. The response is structured data suitable for direct programmatic use.
