Represented as a list of indices and a list of corresponded values, which must be with the same length. - `setMetadata` (body, object) — Metadata to set for the vector. - `namespace` (body, string) — The namespace containing the vector to update. ## Response - `200` — A successful response. - `400` — Bad request. The request body included invalid request parameters. - `4XX` — An unexpected error response. - `5XX` — An unexpected error response. ## Related pages - [Search with a vector](./database-2026-07-data-plane-query.md) - [Search with text](./database-2026-07-data-plane-search-records.md) - [Upsert records](./database-2026-07-data-plane-upsert.md) - [Upsert text](./database-2026-07-data-plane-upsert-records.md) - [Fetch records](./database-2026-07-data-plane-fetch.md) - [Fetch records by metadata](./database-2026-07-data-plane-fetch-by-metadata.md) - [Update a record](./database-2026-07-data-plane-update.md) - [Delete records](./database-2026-07-data-plane-delete.md) - [List record IDs](./database-2026-07-data-plane-list.md) - [Search with a vector](./database-2026-04-data-plane-query.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
