No reviews yet. Be the first to rate this API.
No. OmniStream QR Codes is included with your Omni key, so a single OmniStream key is enough to start calling it. There is no separate signup with the provider and no second key to manage.
A keyless, first-party QR code generator. Turn any text or URL into a PNG QR code with a custom size, colour, and margin. Hosted by OmniStream, always up. Returns image/png. It exposes 1 endpoint over GET, including GET /qr.
Install the OmniStream SDK for your language and call OmniStream QR Codes through it. The client is generated from this API's OpenAPI spec, so parameters and responses are fully typed, and the same client also calls every other API in the marketplace.
You can start on the free plan. OmniStream charges for the unified SDK, key storage and proxy rather than for OmniStream QR Codes itself.
