Sending, paid actions and changes in other apps wait for your yes. The guide A call block works when every row has a number. It fails when the first half hour goes on looking people up. This agent does the lookups before the block starts: whenever people are added to your call list, it fills missing business contact details from Lusha. ## What the agent does It starts when people land on the list you named. It finds the people missing contact details, looks them up in Lusha with your account, and prepares what it found as one approval card. Nothing is saved until you approve. People it could not find are listed by name. ## Set it up 1. Connect Lusha with your API key. 2. Create an agent from scratch: which list to watch and which details to fill. 3. Set it to run when people are added to that list, and keep saving on review. ## Tips - Fill the list a day before the block, so you can review once and call freely. - Pair phone calls with a LinkedIn touch the same day for better connect rates. - Respect local rules for business calls and keep a clear opt-out. **Custom agent***Custom AI agent builder* **Starts** When people are added to a list **Apps** [Lusha](https://prosyo.com/fr/integration/lusha/) **Approval** Sending, paid actions and other apps wait for your yes **Great for** Sales teams, Recruiters **Available on** Penny Agents, Penny SDR and Penny SDR All-in [Start free — 7 days](https://app.prosyo.com/) [Book a demo](https://prosyo.com/fr/) - [How the Custom agent works](https://prosyo.com/fr/ai-agents/custom-ai-agent/) - [All agent use cases](https://prosyo.com/fr/ai-agents/#use-cases) - [Penny pricing](https://prosyo.com/fr/pricing/#penny) Apps in this use case ## Connected in a click, used on your terms Sign in once.

A real person runs the agents on your own ideal customer. [Book a demo](https://prosyo.com/fr/) **Do I need a Lusha account?** Yes. The agent uses your API key, stored encrypted, and Lusha bills its own credits. **Will it overwrite details I already have?** No. It only looks up people with missing details. **What about people it cannot find?** They are listed by name, so you can reach them on LinkedIn instead. **When does it run?** As soon as people are added to the list you choose, whether they come from an import, a form, the Chrome extension or another agent. Nobody has to remember to run it. **Which apps does it use, and do I need accounts?** It uses Lusha, with your API key stored encrypted. Each app works with your own access, so the agent only sees what your account can see, and anything an app charges for is billed by that app. **Can the agent act without my approval?** Reading and research run straight away. Routine work such as saving people to a list or tagging can run alone if you allow it. Sending, paid actions and changes in other apps wait for your yes unless you explicitly allowed that action. **What does a run cost?** Each step uses AI credits like a Penny question, and you set a spending cap for each run. If a run reaches its cap, it waits for you. Paid actions such as enrichment, and charges from connected apps, are separate. **Can I change what the agent does?** Yes, in plain words. Edit the brief, attach a skill such as your own playbook, tick or untick apps and change what needs approval. The next run follows the new instructions, and finished work stays saved. **Which agent runs it?** An agent you create from scratch with this use case as its brief. It takes a few minutes: name it, paste the request, pick the trigger and apps, and choose what needs approval. **How do I see what the agent did?** Every run comes with a plain-English report of what it did, what it cost and anything waiting for you. Results show as formatted answers, tables or diagrams, and you get a notification when a run finishes or needs your approval. **Which Prosyo plan do I need?** Agents come with the Penny Agents, Penny SDR and Penny SDR All-in plans: 5, 10 or 20 agents. Every workspace starts with a 7-day free trial, no card required. ## Your next 10 meetings are already on LinkedIn. 7 days free, no card. Pay later and change your mind? Full refund within 7 days.
