Use the job_id returned by Phone Enrichment Launcher to fetch state and results.

​
Polling vs webhook

If you passed webhook_url when launching the job, you don’t need to call this endpoint at all — Waterfall will automatically deliver the result to your URL as soon as the job is ready. If you didn’t use a webhook, poll this endpoint until status is SUCCEEDED: 
GET /v1/enrichment/phone?job_id={job_id}
Use short exponential backoff — most jobs complete in under 15 seconds. Start with a 2s delay, then 4s, then 8s.

​
Job states

StatusMeaning
RUNNINGJob is still processing. Continue polling.
SUCCEEDEDJob is complete. Phone data is in output.person.

​
Phone number fields

FieldDescription
mobile_phonePrimary phone number in E.164 format, or null if not found.
phone_numbersFull list of numbers found. Empty array [] if none returned.
A SUCCEEDED status does not guarantee a phone number was found — it means the job completed. Always check whether mobile_phone is non-null or phone_numbers is non-empty before billing logic.

​
Response shape

The input.task object always echoes back all fields from the original launch request. Fields not provided will be null.
