LangChain, LlamaIndex, OpenAI Agents SDK and Vercel AI SDK call Grounder from code, as any HTTP client does: a tool that posts the query to /v1/search with an access token for the search scope, as the Search reference describes.
Where a framework’s Tavily or Brave tool lets you change its endpoint, the drop-in endpoints keep that tool as it is. They are not full copies of those APIs.
terminalShell
curl https://api.grounder.net/v1/search \
-H "Authorization: Bearer $GROUNDER_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{"query": "what is the half-life of caffeine", "top_k": 5}'
Python and TypeScript are in the code examples.
