FAQ
About the Google Patents API
The AnyAPI Google Patents API returns Google patents data as normalized JSON from one POST call to /v1/run/google.patents. Search Google Patents with title, patent number, inventor, assignee, key dates, and PDF link. AnyAPI routes each request across 2 sources and falls back automatically when one fails. It costs from $0.85 per 1,000 requests, in US dollars with no subscription and no monthly minimum. Over the last 30 days, 97.5% of Google patents calls through AnyAPI succeeded, with a median response time of 6.1 seconds across 1,314 measured calls.
