## 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 klaviyo-bulk-create-events-preflight-validator-bb6b2b48 -d '<json body>'
```

Example prompt: Before I send my Klaviyo bulk create events request, can you run a preflight check on this JSON payload to make sure it's valid and won't get rejected — the body type is JSON and method is POST?

## When to prefer this

Use this endpoint when you want to validate a Klaviyo bulk_create_events payload before actually submitting it, avoiding wasted API calls, rate limit consumption, or partial failures on malformed data. Ideal for CI/CD pipelines, debugging event ingestion issues, or any workflow that benefits from a dry-run check before committing to the live Klaviyo API.

## Known failure modes

- Invalid or malformed JSON body returns validation error details
- Missing required fields in the bulk events payload flagged as errors
- Unsupported bodyType value causes request rejection
- Network timeout or worker unavailability returns 5xx error
- Malformed input schema structure causes 400 bad request

## How this service works

Bulk Create Events semantic preflight

## Output
