Ken finds work emails for the leads in your campaigns. When you save your own Prospeo key, Ken sends those lookups to Prospeo on your key, so the emails it finds cost 0 Ken credits and Prospeo bills your Prospeo account instead. Finds on your key stay free even when your workspace is out of Ken credits. If your key fails, runs out of Prospeo credits or hits a rate limit, Ken covers the lookup at its normal rate unless you turn Ken fallback off. ## What Syncs **In short:** One-way: Ken calls Prospeo with your key. **What syncs between Ken and Prospeo** | Object | Direction | Frequency | | --- | --- | --- | | Email lookups for your leads | Ken to Prospeo | As Ken enriches each lead | | Work emails found | Prospeo to Ken | Per lookup | | Key status (healthy, invalid, out of credits, rate limited) | Prospeo to Ken | On save, on re-check and on each call | Checked against production on 2026-10-17. ## How to Connect Prospeo **In short:** Connect Prospeo in 4 steps. 1. **Get your Prospeo API key**: In Prospeo, open the API page of your dashboard (app.prospeo.io/api) and copy your API key. 2. **Open provider keys in Ken**: In Ken, go to Settings, then Integrations. Under Email finders, open Prospeo and choose Add key. Only workspace admins can manage provider keys. 3. **Save the key**: Paste the key and save. Ken checks the key with Prospeo before storing it and confirms the account has credits. 4. **Choose the fallback**: Leave Ken fallback for email finders on so campaigns keep finding emails if your key fails, or turn it off to use only your own keys. ## Use Cases **In short:** 3 ways teams use Ken with Prospeo. - Use Prospeo credits you already pay for instead of Ken credits for email finding. - Keep finding emails when the workspace runs out of Ken credits. - Run each agency client workspace on that client's own key. ## Limits **In short:** Prospeo bills each lookup on your key under its own pricing. - Prospeo bills each lookup on your key under its own pricing. - Turn Ken fallback off and Ken makes no lookups of its own when your key fails, so those leads stay without an email. - Ken sends at most 60 lookups a minute to your Prospeo key per workspace, a conservative cap because Ken cannot see your Prospeo plan. - Keys belong to one workspace. Each client workspace needs its own key. - Only workspace admins can add, re-check or remove a key. ## Frequently Asked Questions **In short:** 3 common questions about Ken and Prospeo. ### Does a Prospeo key make email finding free in Ken?
