💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.005	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Patent record (patent-record)	$0.05	Charged for each patent record returned.

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.05 = $5.00 plus the start fee.

📊 What you get

Clean JSON, one record per patent (fields from a live test run):

• publicationNumber — e.g. US20230000001A1
• title · assignee · inventor
• priorityDate · filingDate · publicationDate · grantDate
• snippet — search-match context
• pdfUrl — direct PDF link
• patentUrl — Google Patents page
• abstract · applicationNumber — best-effort: these come from the patent's HTML detail page, which Google rate-limits. The run retries through a residential session; when a page stays blocked the record is still delivered with the search fields and pdfUrl, and the run's status message says how many rows were affected.

Pricing: $0.05 per patent record (Pay-Per-Event) — about 20 patents per $1. Plus a $0.005 Actor start (charged by the platform, one event per GB of memory).
