# Read a space's runtime logs

`GET /v1/spaces/{spaceId}/logs/runtime`

## Request

- Base URL: `https://api.spacefast.com`
- URL: `https://api.spacefast.com/v1/spaces/{spaceId}/logs/runtime`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer

Returns log lines written by the space's own code in the requested window — a Zero capsule's queries and mutations, a PHP function, or a Functions worker's handler. Returns empty data for a static space. An empty page with `hasMore: true` means the scan stopped early, not that the log ended. Lines are collected after the response returns, shipped off the box and indexed before they can be read back, so a line a request just wrote will not be here yet. This is not a live stream, and how far behind it runs is the provider's ingest delay rather than a number we control.

## Path parameters

- `spaceId` string, required

## Query parameters

- `limit` integer: Page size.
- `cursor` string: Opaque cursor from the previous page's `nextCursor`.
- `since` union: Start of the log window.
  - string, date-time
  - string
- `until` union: End of the log window.
  - string, date-time
  - string
- `requestId` string: Return only lines emitted while serving this request.
- `handlerName` string: Return only lines from this handler, either a Zero mutation or a Functions handler.

## Response `200`
