Filters

{
  "batch": ["Summer 2024", "Winter 2024"],
  "industry": ["B2B", "Fintech"],
  "status": ["Active"],
  "regions": ["United States of America"],
  "minTeamSize": 10,
  "isHiring": true,
  "maxItems": 500
}

Leave everything empty and set maxItems: 0 to extract the entire directory.

Monitoring mode (delta)

Turn the scraper into a recurring new-company monitor. Set deltaMode: true, schedule it, and add a webhook — each run returns only the companies added since your last run.

{ "deltaMode": true, "maxItems": 200 }

The first run sets a baseline; every run after returns only new additions (often zero), so you only pay for real signal. State is stored per account.
