6 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

Agent Server graphs can be deployed from other frameworks

Graphs deployed with Agent Server do not have to be written with LangGraph. You can also deploy agents built with other frameworks such as Strands, Claude Agent SDK, Google ADK, and more using the LangGraph Functional API or the deployments-wrap-sdk package.

Deploy tab LangSmith documentation structure

Deploy tab contains six sections: Get started (Deployment components, Develop & test, Frameworks and platforms, Reference with Agent Server API and Control Plane API), Agent Server (Develop your application, Capabilities, How to build, Auth & access control, Server customization), Deploy to Cloud, Deploy to Self-hosted, Prompt & Context Hub, and Sandboxes.

Monitor tab LangSmith documentation structure

Monitor tab contains five sections: Overview (single page), Trace (Tracing setup, Configuration & troubleshooting), Debug (Viewing & managing traces, Bulk export, Messages view, Data type reference), Observe (Monitoring & alerting, Online evaluators, Automations), and Reference (SmithDB SDK migration, LangSmith REST API).

Agent Server API OpenAPI spec location

The Agent Server API specification is located at src/langsmith/agent-server-openapi.json (committed to repository) and is updated via PRs from the langgraph-api repository. The spec generates endpoint pages at /langsmith/agent-server-api/ at deploy time. Validate with 'make check-openapi'.

LangSmith REST API OpenAPI spec

The LangSmith REST API specification is at src/langsmith/langsmith-platform-openapi.json, refreshed daily by .github/workflows/refresh-langsmith-openapi.yml running scripts/process_langsmith_openapi.py. It opens or appends to standing chore/refresh-langsmith-openapi PR. Do not edit by hand. Generates endpoint pages at /langsmith/smith-api/.

Control Plane API OpenAPI spec source

The Control Plane API specification is fetched at deploy time from https://api.host.langchain.com/openapi.json (no local file committed). It generates endpoint pages at /api-reference/. This is the only OpenAPI spec not committed to the repository.
