Blynk-Cloud
Blynk-Cloud is the HTTPS device API behind the Blynk IoT platform: hardware or apps call /external/api/get and /update against blynk.cloud with a per-device auth token to read and write named virtual pins, while a separate OAuth2 Platform API supports building white-labeled IoT products across Prototype, Production, and Enterprise tiers. The API is HTTPS-only — the previously listed https:false was stale — and the old Apiary-hosted docs link no longer documents Blynk at all: Apiary has been sunset and that page now serves an unrelated third-party 'Polls' API spec. Current docs live at docs.blynk.io.

- Get a key at the provider
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
