Path parameters

Field

Description

vector_store_id

string

batch_id

string

Required field. The ID of the file batch that the files belong to.

Query parameters

Field

Description

limit

integer

  • asc
  • desc

after

string

A cursor for use in pagination. after is an object ID that defines your place in the list. For instance, if you make a list request and receive 100 objects, ending with obj_foo, your subsequent call can include after=obj_foo in order to fetch the next page of the list.

before

Field

Description

object

string

Required field.

data[]

VectorStoreFileObject

Required field. A list of files attached to a vector store.

first_id

string

Required field.

last_id

string

Required field.

has_more

boolean

Required field.

VectorStoreFileObject

A list of files attached to a vector store.

Field

Description

id

string

Required field. The identifier, which can be referenced in API endpoints.

object

enum

Required field. The object type, which is always vector_store.file.

  • vector_store.file

usage_bytes

integer

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

created_at

integer

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

vector_store_id

string

last_error

Any of LastError0 | null

chunking_strategy

Any of StaticChunkingStrategyResponseParam | OtherChunkingStrategyResponseParam

attributes

Any of object (map<string, string>) | null

LastError0

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

Field

Description

code

enum

Required field. One of server_error, unsupported_file, or invalid_file.

  • server_error
  • unsupported_file
  • invalid_file

message

string

Required field. A human-readable description of the error.
