## 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 cloud-usage-imports-csv-header-contract-check-94025940 -d '<json body>'
```

Example prompt: Can you check whether my cloud usage CSV file has valid headers and conforms to the expected contract? The file uses comma delimiters, and I want to make sure columns like usage_id, reported_on, resource_id, used_units, and billed_amount are all correctly formatted, with allowed categories group-a and group-b, and billed_amount values between 0 and 10000.

## When to prefer this

Choose this endpoint when you need a lightweight, fast, and low-cost ($0.01 USDC) validation of a cloud usage CSV file's header contract before importing into a billing or analytics system. It is purpose-built for the cloud usage domain (usage_id, reported_on, resource_id, used_units, billed_amount schema) and supports configurable delimiters, category allowlists, and numeric bounds — making it ideal for automated pipeline quality gates or pre-upload sanity checks where full data enrichment is not needed.

## Known failure modes

- CSV exceeds 100,000 character limit — rejected with size error
- More than 1000 rows submitted — only header contract checked up to limit
- Invalid delimiter specified — must be comma, semicolon, or tab
- Empty CSV string submitted — validation cannot proceed
- Cell values contain unrecognized categories not in allowed_categories list
- Numeric values outside declared minimum/maximum bounds flagged as violations
- Malformed quoted cells may cause parse errors if quoting is inconsistent

## How this service works

Cloud usage imports — Header contract check: Header contract check for Cloud usage 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 header contract check report.

## Output

Returns a structured header contract check report indicating whether the CSV conforms to the declared schema, including column presence and ordering, data type conformance per column, out-of-range numeric values, disallowed category values, cell length violations, and row-level error details for up to 1000 rows.
