## 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 build-result-imports-header-contract-check-db39dfd6 -d '<json body>'
```

Example prompt: Can you check whether my build results CSV has valid headers and column contract? It uses comma delimiters and my CSV has columns build_id, built_on, repository_id, duration_seconds, warning_count — here's the data, please run a header contract check and flag any violations.

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.01 USDC) structural validation of build result CSV files specifically — verifying that column headers, data types, numeric ranges, and category values conform to a declared contract before ingesting data into a pipeline or warehouse. Prefer it over general-purpose CSV validators when your data fits the build_id/built_on/repository_id/duration_seconds/warning_count schema pattern and you need a focused, schema-aware header contract report without external enrichment.

## Known failure modes

- CSV exceeds 1000 row limit — report truncated or rejected
- Cell exceeds max_cell_length setting — validation error flagged
- Delimiter mismatch causes parsing failure — columns not detected correctly
- allowed_categories list empty or mismatched — all category values flagged as violations
- Malformed CSV with unbalanced quotes — parse error returned
- Numeric values outside min/max bounds — range violations reported
