Errors

This operation returns a list of all indexes in a project.

List indexes

This operation deploys a Pinecone index. This is where you specify the measure of similarity, the dimension of vectors to be stored in the index, which cloud provider you would like to deploy with, and more.
  
For guidance and examples, see [Create an index](https://docs.pinecone.io/guides/indexes/create-an-index#create-a-serverless-index).


Describe an index

This operation deletes an existing index.

This operation configures an existing index. 

For serverless indexes, you can configure index deletion protection, tags, and integrated inference embedding settings for the index. For pod-based indexes, you can configure the pod size, number of replicas, tags, and index deletion protection.

It is not possible to change the pod type of a pod-based index. However, you can create a collection from a pod-based index and then [create a new pod-based index with a different pod type](http://docs.pinecone.io/guides/indexes/create-an-index#create-an-index-from-a-collection) from the collection. For guidance and examples, see [Configure an index](http://docs.pinecone.io/guides/indexes/configure-an-index).

The `describe_index_stats` operation returns statistics about the contents of an index, including the vector count per namespace, the number of dimensions, and the index fullness.

Serverless indexes scale automatically as needed, so index fullness is relevant only for pod-based indexes.

Get index stats

The `upsert` operation writes vectors into a namespace. If a new value is upserted for an existing vector ID, it will overwrite the previous value.

For guidance and examples, see [Upsert data](https://docs.pinecone.io/guides/data/upsert-data).

Upsert vectors

The `query` operation searches a namespace, using a query vector. It retrieves the ids of the most similar items in a namespace, along with their similarity scores.

For guidance and examples, see [Query data](https://docs.pinecone.io/guides/data/query-data).

Query vectors

The `fetch` operation looks up and returns vectors, by ID, from a single namespace. The returned vectors include the vector data and/or metadata.

For guidance and examples, see [Fetch data](https://docs.pinecone.io/guides/data/fetch-data).

Fetch vectors

The `update` operation updates a vector in a namespace. If a value is included, it will overwrite the previous value. If a `set_metadata` is included, the values of the fields specified in it will be added or overwrite the previous value.

For guidance and examples, see [Update data](https://docs.pinecone.io/guides/data/update-data).

Update a vector

The `list` operation lists the IDs of vectors in a single namespace of a serverless index. An optional prefix can be passed to limit the results to IDs with a common prefix.

`list` returns up to 100 IDs at a time by default in sorted order (bitwise "C" collation). If the `limit` parameter is set, `list` returns up to that number of IDs instead. Whenever there are additional IDs to return, the response also includes a `pagination_token` that you can use to get the next batch of IDs. When the response does not include a `pagination_token`, there are no more IDs to return.

For guidance and examples, see [List record IDs](https://docs.pinecone.io/guides/data/list-record-ids).

**Note:** `list` is supported only for serverless indexes.

List vector IDs

The `start_import` operation starts an asynchronous import of vectors from object storage into an index.

For guidance and examples, see [Import data](https://docs.pinecone.io/guides/data/import-data).

Start import

The `list_imports` operation lists all recent and ongoing import operations.

By default, `list_imports` returns up to 100 imports per page. If the `limit` parameter is set, `list` returns up to that number of imports instead. Whenever there are additional IDs to return, the response also includes a `pagination_token` that you can use to get the next batch of imports. When the response does not include a `pagination_token`, there are no more imports to return.

For guidance and examples, see [Import data](https://docs.pinecone.io/guides/data/import-data).

List imports

The `describe_import` operation returns details of a specific import operation. 

For guidance and examples, see [Import data](https://docs.pinecone.io/guides/data/import-data).

Describe an import

The `cancel_import` operation cancels an import operation if it is not yet finished. It has no effect if the operation is already finished.

For guidance and examples, see [Import data](https://docs.pinecone.io/guides/data/import-data).

Cancel an import

Generate embeddings for input data.

For guidance and examples, see [Generate embeddings](https://docs.pinecone.io/guides/inference/generate-embeddings).

Embed data

Rerank documents according to their relevance to a query.

For guidance and examples, see [Rerank documents](https://docs.pinecone.io/guides/inference/rerank).

This operation creates a serverless integrated inference index for a specific embedding model.

Refer to the [model guide](https://docs.pinecone.io/guides/inference/understanding-inference#embedding-models) for available models and model details.

Create an index for an embedding model

This operation converts input data to vector embeddings and then upserts the embeddings into a namespace.

Upsert records into a namespace

This operation converts a query to a vector embedding and then searches a namespace using the embedding. It returns the most similar records in the namespace, along with their similarity scores.

Search a namespace

This operation returns a list of all assistants in a project.

List assistants

The `create_assistant` endpoint [creates a Pinecone Assistant](https://docs.pinecone.io/guides/assistant/create-assistant). This is where you specify the underlying training model, which cloud provider you would like to deploy with, and more.

The `get_assistant` endpoint [gets the status](https://docs.pinecone.io/guides/assistant/manage-assistants#get-the-status-of-an-assistant) of an assistant.

Check assistant status

The `update_assistant` endpoint [updates an existing assistant](https://docs.pinecone.io/guides/assistant/manage-assistants#update-an-existing-assistant). You can modify the assistant's instructions and metadata.

Update an assistant

The `delete_assistant` endpoint [deletes an existing assistant](https://docs.pinecone.io/guides/assistant/manage-assistants#delete-an-assistant).

Delete an assistant

The `list_files` endpoint returns a [list of all files in an assistant](https://docs.pinecone.io//guides/assistant/manage-files#list-files-in-an-assistant), with an option to filter files with metadata.

List Files

The `upload_file` endpoint [uploads a file](https://docs.pinecone.io/guides/assistant/upload-file) to the specified assistant.

Upload file to assistant

The `describe_file` endpoint provides the [current status and metadata of a file](https://docs.pinecone.io/guides/assistant/manage-files#get-the-status-of-a-file) uploaded to an assistant.

Describe a file upload

The `delete_file` endpoint [deletes an uploaded file](https://docs.pinecone.io/guides/assistant/manage-files#delete-a-file) from an assistant.

Delete an uploaded file

The `chat_assistant` endpoint allows you to [chat with an assistant](https://docs.pinecone.io/guides/assistant/chat-with-assistant) and get back citations in structured form. 

This is the recommended way to chat with an assistant, as it offers more functionality and control over the assistant's responses and references than the `chat_completion_assistant` endpoint.

The `chat_completion_assistant` endpoint is used to [chat with an assistant](https://docs.pinecone.io/guides/assistant/chat-with-assistant). This endpoint is based on the OpenAI Chat Completion API, a commonly used and adopted API. 

It is useful if you need inline citations or OpenAI-compatible responses, but has limited functionality compared to the [`chat_assistant`](https://docs.pinecone.io/reference/api/2024-07/assistant/chat_assistant) operation.

Chat through an OpenAI-compatible interface

The `metrics_alignment` endpoint [evaluates](https://docs.pinecone.io/guides/assistant/understanding-evaluation)  the correctness, completeness, and alignment of a generated answer with respect to a question and a ground truth answer.  The correctness and completeness are evaluated based on the precision and recall of the generated answer with respect to the ground truth answer facts.  Alignment is the harmonic mean of correctness and completeness.


Evaluate an answer

The `context_assistant` endpoint allows you to retrieve context from an assistant that might be used as part of RAG or any agentic flow.
