Summary

Adds credential setup documentation for two new credential types used by the n8n AI Agent. The corresponding credential type definitions (BraveSearchApi, DaytonaApi) are being added to @n8n/nodes-langchain in the main n8n repo. These credentials are used internally by Instance AI for web search and sandbox functionality but credentials could be useful with http node too.

  • Brave Search (bravesearch.md) -- API key setup via the Brave Search API dashboard
  • Daytona (daytona.md) -- API URL and API key setup via the Daytona dashboard

Summary by cubic

Add credential setup docs for Brave Search and Daytona and update the docs nav. Supports the new BraveSearchApi and DaytonaApi in @n8n/nodes-langchain used by Instance AI for search and sandbox.

Written for commit b3316e0. Summary will update on new commits.
