Overview

Blynk-Cloud controls IoT devices — token-based (an invalid token returns 400, verified).

Quick Start

Pin (replace YOUR_TOKEN):

curl "https://blynk.cloud/external/api/get?token=YOUR_TOKEN&pin=V0"
{ "error": { "message": "Invalid token." } }

Authentication

  • Blynk app → device auth token.
  • Send it as the token query parameter (invalid → 400, verified).

Rate Limits & Notes

  • Free tier with limits (check the docs); paid plans scale.
  • IoT device control.

FAQ

Is Blynk free? Free tier with limits; more is paid.

Why 400? Invalid tokens return 400 (verified) — use the device token.

What’s the auth style? token query parameter.
