Find app developers to pitch - a filtered lead list with each developer's best scored business email (Studio plan).

1+ credits1 per pageoperationId listDevelopers

Developer lead lists (Studio). Filter by store, top category, country, total ratings range, app count, last app update and email quality; page with cursor. Each row has the developer's profile, reach and the best business contact we found and scored (email, email_score 0-100, email_role, email_mx_ok). Personal addresses, addresses that failed the MX check or opted out, and developers who asked not to be contacted are never returned. 1 credit per page (up to 500 rows). Other plans get 402 plan_limit; GET /v1/developers/{dev} works on every plan.
