## 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 sensor-observation-imports-csv-whitespace-audit-f0049d70 -d '<json body>'
```

Example prompt: Can you run a whitespace audit on this sensor observation CSV — it uses comma delimiters, has temperature and humidity readings, and I want to flag any cells longer than 500 characters or values outside -50 to 150?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) whitespace-specific audit of sensor observation CSV data before import or processing, especially when your data involves environmental readings (temperature, humidity) with known sensor group categories and you want cell-level whitespace validation without external enrichment or data transformation.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — rows beyond limit may be ignored or rejected
- Invalid delimiter value outside enum [',',';','\t'] — schema validation error
- Cell content exceeds max_cell_length — flagged as violation
- Malformed CSV with unmatched quotes — parse error returned
- Empty CSV string — minimum length violation

## How this service works

Sensor observation imports — Whitespace audit: Whitespace audit for Sensor observation 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 whitespace audit report.

## Output

Returns a whitespace audit report for the submitted sensor observation CSV, including identified whitespace violations at the cell or row level, validation status, and any rows that failed checks based on the configured minimum/maximum values, allowed categories, and max cell length constraints.
