Retrieve vector store file

get /vector_stores/\{vector_store_id\}/files/\{file_id\}

Retrieves a vector store file.

Path Parameters

• vector_store_id: string

• file_id: string

Returns

• VectorStoreFile object \{ id, created_at, last_error, 6 more \}

  A list of files attached to a vector store.

  • id: string

    The identifier, which can be referenced in API endpoints.

  • created_at: number

    The Unix timestamp (in seconds) for when the vector store file was created.

  • last_error: object \{ code, message \} or null

    The last error associated with this vector store file. Will be null if there are no errors.

    • code: "server_error" or "unsupported_file" or "invalid_file"

      One of server_error, unsupported_file, or invalid_file.

      • "server_error"

      • "unsupported_file"

      • "invalid_file"

    • message: string

      A human-readable description of the error.

  • object: "vector_store.file"

    The object type, which is always vector_store.file.

    • "vector_store.file"

  • status: "in_progress" or "completed" or "cancelled" or "failed"

    The status of the vector store file, which can be either in_progress, completed, cancelled, or failed. The status completed indicates that the vector store file is ready for use.

    • "in_progress"

    • "completed"

    • "cancelled"

    • "failed"

  • usage_bytes: number

    The total vector store usage in bytes. Note that this may be different from the original file size.

  • vector_store_id: string

    The ID of the vector store that the File is attached to.

  • attributes: optional map[string or number or boolean] or null

    Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard. Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters, booleans, or numbers.

    • string

    • number

    • boolean

  • chunking_strategy: optional StaticFileChunkingStrategyObject or OtherFileChunkingStrategyObject

    The strategy used to chunk the file.

    • StaticFileChunkingStrategyObject object \{ static, type \}

      • static: StaticFileChunkingStrategy

        • chunk_overlap_tokens: number

          The number of tokens that overlap between chunks. The default value is 400.

          Note that the overlap must not exceed half of max_chunk_size_tokens.

        • max_chunk_size_tokens: number

          The maximum number of tokens in each chunk. The default value is 800. The minimum value is 100 and the maximum value is 4096.

      • type: "static"

        Always static.

        • "static"

    • OtherFileChunkingStrategyObject object \{ type \}

      This is returned when the chunking strategy is unknown. Typically, this is because the file was indexed before the chunking_strategy concept was introduced in the API.

      • type: "other"

        Always other.

        • "other"
