Freepik's developer API is now branded Magnific, at https://api.magnific.com (the older api.freepik.com host still answers). It covers stock-content search and AI image generation; generation is asynchronous — submit, then poll the task.
Get a key at magnific.com and send it as the x-magnific-api-key header. In the examples it's written {{MAGNIFIC_API_KEY}}.
