→To capture 100% of businesses across a dense metro area (e.g., all 1,800 restaurants in Manhattan), subdivide the city into a 0.02° × 0.02° latitude/longitude grid and query GET /v1/places/nearby.

Pricing & Cost Analysis · 20268 min read · Updated 2026-11-05

Outscraper Pricing Breakdown (2026): Real Cost per 1,000 Leads, Add-On Multipliers & Sync API Comparison

Outscraper advertises $3.00 per 1,000 Google Maps places on its medium tier (501–100,000 records), but chaining Domain Emails (+$3/1K) and Email Verification (+$3/1K) pushes real B2B lead costs to $6–$9/1K while async CSV queues take 30–180 seconds.
