Free image-generation API lets developers skip accounts using anonymous credit tokens

A free image-generation API called Kavel allows developers to generate AI images without creating an account, verifying a phone number, or using an API key — users simply invent an identifier string that acts as their wallet key. The anonymous tier provides 15 credits, enough for up to three text-to-image generations at 5 credits each or exactly one image-edit operation at 15 credits, while video generation at 40 credits is structurally impossible on the free tier. A notable quirk of the API is that all failure modes — including hitting the credit wall or requesting an unaffordable operation — return HTTP 200 responses, making errors indistinguishable from successes without parsing the response body. A lightweight Python package called 'kavel', available on PyPI, wraps the two required HTTP calls and returns a watermarked CDN image URL with no third-party dependencies. The API also supports image-to-image editing that preserves structural details while altering only the prompted elements, such as changing lighting conditions in a scene.
