I plan to use your API inside an n8n agent to generate leads and fully automate my lead generation workflow. Could you please confirm:
1. How many API credits are included with the Tier 2 plan, and how are credits consumed (per lead, per email, per request, etc.)?
2. Is the lead data available worldwide, or is it limited to specific countries or regions?
3. Are the email addresses verified, and if so, what level of verification is applied (e.g., syntax check, domain check, inbox verification)?
4. Are there any rate limits or restrictions when using the API for automation tools like n8n?

Thanks in advance for your help. Looking forward to your clarification so I can move forward with the purchase.
