- `ids`: Fetch the documents with the given IDs.
- `filter`: Fetch every document matching a metadata filter expression. Results are returned a page at a time, holding `limit` documents per page (100 by default, 10000 at most). When there are more documents to return, the response includes a `pagination` token you can pass back as `pagination_token` to retrieve the next page. When no `pagination` token is returned, there are no more documents to fetch.

:::callout{intent="note"}
Text-match operators (`$match_phrase`, `$match_all`, `$match_any`) are supported in a filtered fetch, as they are in [search](/guides/database-2026-07-data-plane-search-documents). A filtered [update](/guides/database-2026-07-data-plane-update-documents) or [delete](/guides/database-2026-07-data-plane-delete-documents) rejects them with a `400`.

## Authorizations

- `Authorization` (header, string, required) — Bearer authentication header of the form `Bearer <token>`.

## Path Parameters

- `namespace` (path, string, required) — The namespace to fetch documents from.

## Headers

- `X-Pinecone-Api-Version` (header, string, required) — Required date-based version header

## Body

- `ids` (body, string\[]) — A list of document IDs to fetch. Mutually exclusive with `filter`.
- `filter` (body, object) — A metadata filter expression selecting the documents to fetch. Must not be empty; an empty filter is rejected rather than matching every document. Mutually exclusive with `ids`.
- `include_fields` (body, string\[]) — The document fields to return on each document. When omitted or empty, all fields are returned; `["*"]` also returns every field.
- `pagination_token` (body, string) — A pagination token from a previous fetch response, used to retrieve the next page of matching documents. Only valid together with `filter`.
- `limit` (body, integer) — The maximum number of documents to return per page. Only applies to a fetch by `filter`; a fetch by `ids` is already bounded by `ids` and ignores an in-range value, but a value outside 1-10000 is rejected on either form. Defaults to 100.

## Response

- `200` — A successful fetch response.
- `400` — Bad request. The request body included invalid request parameters.
- `401` — Unauthorized. Possible causes: missing or invalid API key.
- `4XX` — An unexpected error response.
- `5XX` — An unexpected error response.
