# Submit Bulk Verification Job

> Submit a list of email addresses for bulk verification. Returns a job ID immediately. Poll GET /v1/bulk/{job_id} to track progress.

Use this endpoint to submit a list of email addresses for asynchronous bulk verification. The API accepts your list, deduplicates it, queues the job, and returns a `job_id` immediately. Verification happens in the background — you poll [GET /v1/bulk/\{job\_id}](/docs/api-reference/bulk-status) to track progress and [GET /v1/bulk/\{job\_id}/results](/docs/api-reference/bulk-results) to retrieve results when the job is complete.

## Deduplication and async processing

OrbiSearch automatically deduplicates your email list before processing. If you submit 600 addresses but 100 are duplicates, `total_emails` will be `500` and you will only be charged for 500 verifications.

Because bulk jobs run asynchronously, this endpoint returns immediately after accepting the job. Use the returned `job_id` to poll [GET /v1/bulk/\{job\_id}](/docs/api-reference/bulk-status) until the `status` field reaches `complete`. You can begin retrieving partial results at any time using [GET /v1/bulk/\{job\_id}/results](/docs/api-reference/bulk-results) — see that page for details on fetching results before a job finishes.

    **Rate limiting:** requests are limited per API key (20 requests per second
    by default). Every response includes `X-RateLimit-Limit`,
    `X-RateLimit-Remaining` and `X-RateLimit-Reset` headers describing the
    current per-key window so clients can self-throttle; `429` responses also
    include a `Retry-After` header with the suggested backoff in seconds.
