Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 prediction-result-imports-csv-header-contract-check-4f40bb0f -d '<json body>'
```

Example prompt: Can you check the header contract on my prediction results CSV — it has columns prediction_id, predicted_on, model_id, probability, and latency_ms, with comma as the delimiter and allowed categories of group-a and group-b? I want to make sure everything is valid before I import it.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) contract validation of a prediction result CSV's header structure before ingesting it into a pipeline. It is purpose-built for prediction import schemas (prediction_id, model_id, probability, etc.) with support for quoted cells and configurable delimiters, making it preferable to generic CSV validators when your domain is ML prediction output data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- Delimiter mismatch causes parsing failures and false column errors
- Allowed categories list empty but categorical columns present — may produce unexpected results
- CSV fewer than 1 row returns error
- Cell length exceeds max_cell_length — flagged as violation
- Minimum/maximum range misconfigured — numeric columns incorrectly flagged

## How this service works

Prediction result imports — Header contract check: Header contract check for Prediction result 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

A CSV header contract check report indicating whether the supplied CSV's headers and structure conform to the declared contract, including any violations of column names, value ranges, cell length limits, delimiter usage, or category constraints across up to 1000 rows.
