## 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 return-imports-valid-row-export-5a39b925 -d '<json body>'
```

Example prompt: Validate my returns CSV and export only the valid rows — the file uses comma delimiters, allowed reason codes are group-a and group-b, numeric values should be between 0 and 1000000, and here's the CSV: return_id,received_on,reason_code,returned_units,restocking_fee\nrecord-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3

## When to prefer this

Choose this endpoint when you need to validate a return imports CSV against a declared table contract and extract only conforming rows, particularly when you need to enforce allowed category values for reason codes, numeric range bounds, and cell length constraints. It is purpose-built for the returns domain schema (return_id, received_on, reason_code, returned_units, restocking_fee) and handles quoted cells. Prefer this over generic CSV validators when you need domain-specific returns data contract enforcement with a clean valid-row output.

## Known failure modes

- CSV exceeds 100,000 character limit — rejected with size error
- Rows exceed 1000 row maximum — only first 1000 processed or error returned
- Invalid delimiter character not in allowed enum — validation error
- Cell content exceeds max_cell_length — those cells or rows flagged invalid
- No rows pass validation — empty valid row set returned
- Malformed CSV (unmatched quotes, structural errors) — parse failure

## How this service works

Return imports — Valid row export: Valid row export for Return imports. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV valid row export report.

## Output

A valid row export report listing only the rows from the submitted CSV that pass all declared contract rules — including numeric range checks, allowed category membership for reason codes, cell length limits, and proper CSV structure. Rows failing any constraint are excluded from the output.
