# Batch query server keys

`POST /_matrix/key/v2/query`

Notary lookup for a batch of servers, each returned verbatim as its origin signed it. Malformed JSON gets a 400. An empty batch (valid body, no server_keys) gets a 200 with an empty key set: you asked for nothing, you got nothing.

## Query parameters

- `minimum_valid_until_ts` integer

## Request body

- GithubComEtkeccMrsInternalModelQueryServerKeysRequest
  - `server_keys` object

## Response `200`

Signed server keys, or an empty key set for an empty batch

- GithubComEtkeccMrsInternalModelServerKeysQueryResponse
  - `server_keys` array[] — each element is a signed ServerKeys object
    - integer[]

## Other responses

- `400` — Request body is not valid JSON
