  title: Deno Deploy REST Apps Logs API
  description: The Deno Deploy REST API (v1) provides programmatic access to manage projects and deployments on the Deno Deploy serverless edge platform. It exposes endpoints for creating and managing organizations, projects, deployments, domains, and KV databases, as well as retrieving analytics and usage metrics. Authentication uses HTTP Bearer tokens generated from the Deno Deploy dashboard. This v1 API is scheduled for sunset on July 20, 2026; users should migrate to the v2 API.

      description: Queries or streams runtime logs for an application. A start datetime is required. When an end datetime is omitted, the endpoint streams logs in real time using Server-Sent Events or newline-delimited JSON depending on the Accept header. Supports filtering by revision ID, log level, and full-text search. Cursor-based pagination applies to historical queries.
