  • API key authentication — Send your key in the X-Api-Key header on every request; a free key allows 1,000 requests a month and 45 a minute.

The same endpoints, the same q, f, s and o parameters and the same response shape. The base URL is https://patentref.io/api/v1/, and every request sends your key in X-Api-Key.

R (the patentsview package)

library(patentsview)
Sys.setenv(PATENTSVIEW_API_KEY = "YOUR_KEY")
assignInNamespace("get_base", function(endpoint) sprintf("https://patentref.io/api/v1/%s/", endpoint), ns = "patentsview")

Python

import requests
BASE = "https://patentref.io/api/v1/"
print(requests.get(BASE + "patent/", params={"q": '{"patent_id":"10905426"}'}, headers={"X-Api-Key": "YOUR_KEY"}).json())

YOUR_KEY stands for your key. A free key allows 1,000 requests a month and 45 a minute.
