Client

Add runs to an annotation queue with the specified queue ID.

Awaits all pending trace batches. Useful for environments where you need to be sure that all tracing requests finish before execution ends, such as serverless environments.

Batch ingest/upsert multiple runs in the Langsmith system.

Cleanup resources held by the client. Stops the cache's background refresh timer.

Clone a public dataset to your own langsmith tenant. This operation is idempotent. If you already have a dataset with the given name, this function will do nothing.

Create an annotation queue on the LangSmith API.

Create a feedback configuration on the LangSmith API.

This upserts: if an identical config already exists, it returns it. If a conflicting config exists for the same key, a 400 error is raised.

Creates a presigned feedback token and URL.

The token can be used to authorize feedback metrics without needing an API key. This is useful for giving browser-based applications the ability to submit feedback without needing to expose an API key.

Delete an annotation queue with the specified queue ID.

Delete multiple examples by ID.

Delete a feedback configuration on the LangSmith API.

Delete a run from an an annotation queue.

Flushes current queued traces.

Get a run from an annotation queue at the specified index.

Get the size of an annotation queue.

List the annotation queues on the LangSmith API.

List feedback configurations on the LangSmith API.

Retrieves a list of presigned feedback tokens for a given run ID.

List runs from the LangSmith server.

Get shared examples.

Batch ingest/upsert multiple runs in the Langsmith system.

Read an annotation queue with the specified queue ID.

Get dataset version by closest date or exact tag.

Use this to resolve the nearest version to a given timestamp or for a given tag.

Lets you run a similarity search query on a dataset.

Requires the dataset to be indexed. Please see the indexDataset method to set up indexing.

Update an annotation queue with the specified queue ID.

Update a dataset

Updates a tag on a dataset.

If the tag is already assigned to a different version of this dataset, the tag will be moved to the new version. The as_of parameter is used to determine which version of the dataset to apply the new tags to.

It must be an exact version of the dataset to succeed. You can use the "readDatasetVersion" method to find the exact version to apply the tags to.

Update examples with attachments using multipart form data.

Update a feedback configuration on the LangSmith API.
