API Reference¶
The LangGraph Cloud API reference is available with each deployment at the /docs URL path (e.g. http://localhost:8124/docs).
Click here to view the API reference.
Authentication¶
For deployments to LangGraph Cloud, authentication is required. Pass the X-Api-Key header with each request to the LangGraph Cloud API. The value of the header should be set to a valid LangSmith API key for the organization where the API is deployed.
Example curl command:
curl --request POST \
--url http://localhost:8124/assistants/search \
--header 'Content-Type: application/json' \
--header 'X-Api-Key: LANGSMITH_API_KEY' \
--data '{
"metadata": {},
"limit": 10,
"offset": 0
}'
