Listed in the Hermes plugin catalog

SerpKite is in the Hermes plugin catalog as serpkite (marketplace page). Hermes installs the version its maintainers reviewed.

Overview

What Hermes Agent is, and where SerpKite fits

Hermes Agent by Nous Research picks a web backend for its built-in web_search and web_extract tools. The SerpKite plugin (SerpKite/serpkite-hermes-plugin, MIT) registers serpkite as that backend, so the agent searches Google and reads pages through your SerpKite key.

Search calls /v1/search and returns up to 10 results per call (1 credit). Extract calls /v1/webpage once per URL (1 credit per page): pages that need JavaScript are rendered in a browser and PDFs are read from their text layer. Failed requests are not billed.
