AI Agent Best Practices

Use filters

Narrow your queries with filters like tech=quickbooks or country=Canada to get the most relevant leads. Each request returns up to 25 leads.

Workflow pattern

Set up a trigger in N8N, Make, Zapier, or a Python script. Call GET /leads?tech=quickbooks&country=Canada, process the returned leads, and use the lead IDs to track which ones you've already handled.
