Sirv

Verified Jul 2026

Sirv's REST API covers file upload and management, image and video optimization, and URL-based on-the-fly manipulation (resize, crop, format conversion) served through its global CDN, with full reference docs at apidocs.sirv.com. Authentication exchanges an account's API client ID and secret for a short-lived Bearer token via a POST to api.sirv.com/v2/token — a live probe without credentials correctly returned a 400 validation error rather than a network failure, with Access-Control-Allow-Origin: * present even on that error response. Pricing follows a freemium model: a free plan covers a small storage/bandwidth allowance, with paid tiers scaling by storage and bandwidth used.

Auth quickstart

  1. Sign up with the provider to get an API key.
  2. Send it on every request as a headerAuthorization: <key>
  3. The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored

Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
