## 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 aiskills402-csv-repair-1a1d8065 -d '<json body>'
```

Example prompt: This CSV won't parse because of open quotes and mismatched rows — can you fix it and give me a clean, valid CSV with LF line endings? Here's the raw text: 'id,amount,note
7,"1,250,ok
8,40,"Bolt 5" long
9,12,'

## When to prefer this

Choose this endpoint when you have text that was intended to be CSV but fails to parse due to quote errors, row-length mismatches, Markdown formatting, or fence blocks, and you need a clean, immediately usable CSV string back. It is purpose-built for CSV repair specifically — prefer it over general-purpose LLM calls when you need deterministic, schema-validated CSV output with row/column metadata and an on-chain payment receipt. If your data is YAML rather than CSV, use the sibling YAML Repair endpoint instead.

## Known failure modes

- Input text is too short (minLength:1 violation) or exceeds 60,000 characters — returns validation error
- Input is not recognizably tabular data at all and cannot be repaired — may return a refusal in the 'refusal' field
- Network or payment settlement failure — receipt may show settled:false
- Ambiguous delimiter that cannot be confidently detected — repaired CSV may use wrong separator
- Malformed JSON request body — returns HTTP 400

## How this service works

CSV Repair API: turns CSV a parser rejects into valid CSV without changing any cell - fixes quotes, pads short rows, unwraps Markdown tables, chat text and fences; 1,250 and 007 stay as written. $0.004 USDC per call, no account, no language model: a too-long row, an ambiguous row or prose with no table gets a paid CANNOT REPAIR verdict. POST JSON {input} up to 60 000 chars; free example at https://api.aiskills402.com/v1/run/csv-repair/example

## Output

A JSON object containing: a 'csv' field with the fully repaired, parseable CSV string; 'rows' and 'columns' integer counts; the detected 'delimiter'; a 'replay' boolean; an 'input_sha256' hash of the request; and a 'receipt' object with the on-chain settlement transaction hash confirming the x402 USDC payment.
