## 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-f41dff0e -d '<json body>'
```

Example prompt: Parse this CSV into JSON rows for me — it has headers in the first row and I want numbers coerced to actual numeric types: 'name,age,score\nAlice,30,95.5\nBob,25,88.0'

## When to prefer this

Choose this endpoint when you need to parse raw CSV text (including TSV or other delimited variants) into structured JSON rows in a single API call, especially when the delimiter is unknown or variable, when quoted fields containing delimiters are present, when type coercion of numbers/booleans is needed, or when you need to surface per-row parse errors for data quality validation. Prefer this over client-side parsing when operating in an agentic pipeline without a local CSV library.

## Known failure modes

- Malformed CSV with unclosed quotes may result in partial parse or error
- Empty input body returns error
- CSV with inconsistent column counts per row surfaces per-row errors
- Extremely large CSV payloads may timeout on the Workers runtime
- Ambiguous delimiter when multiple candidates score equally may pick wrong one

## How this service works

Parse CSV into JSON rows — auto-detects the delimiter, handles quoted fields and headers, optional type coercion. Returns columns, row count, and per-row parse errors.

## Output

Returns a JSON object containing: an array of column names, total row count, an array of parsed row objects (each field keyed by column header), and an array of per-row parse errors with row index and error detail. If type coercion is enabled, numeric and boolean fields are returned as native JSON types rather than strings.
