+# `SERPent`
+
+## SERP results scrapping
+
+SERPent exposes an unified API to query SERP (Search Engine Result Pages) for a few common search engines, namely:
+
+- DuckDuckGo
+- Brave
+- Bing
+- Google Patents
+- Google
+
+The application uses the `playwright` library to control a headless web browser, to simulate normal user activity, to fool the anti-bot measures often present on those sites. See the `/serp/` endpoints for search results scrapping.
+
+
+## Website sources scrapping
+
+SERPent also exposes a few endpoints to scrap the contents of certain sources (patents, scholar). See the `/scrap/` endpoints for supported website sources scrapping.
