About this item

Freshness. pipe0 doesn't say how fresh an answer is.
1 of the 6 key fields we check. Deliverability.
A balance you top up. You pay $10 or more. You spend all of it on calls.
One call. You call POST /v1/pipes/run/sync. You send pipes ([{"pipe_id": "email:validate:zerobounce@1"}]) and input (up to 100 records, each with email). You can also send config, field_annotations, scopes, and each pipe's config, run_if and connector. The call returns the answer when the provider is quick. When the provider is slow, the call returns a job. You fetch the answer once the job is done.
Who can get it: businesses only, in the course of their trade, business or profession. Keep data: no time limit, not cached or shared to avoid running a pipe. Use data: with conditions.
