What Free AI API is
Free AI API is a practical directory for finding free-to-use AI APIs that people can actually try. It covers language models, image generation, voice, video, speech-to-text, and coding models, with entries organized by provider, capability, quota type, signup requirement, examples, and availability signals.
Compare before you integrate
The directory is designed to answer the questions that usually slow down a prototype: Is the endpoint still online? Does it require a credit card? Is the quota long-term, credit-based, rate-limited, or part of a temporary promotion? What model does it expose, what can it do, and where is the provider's signup or API documentation? Browse by category, provider, or model, then open a detailed endpoint page with the relevant usage notes and code-oriented guidance.
A browser playground and living reference
Free AI API includes a browser playground where visitors can choose a model, paste their own free provider key, and try a request. The key is sent once for the provider call and is not stored by the directory. The site also publishes API key guides, model comparisons, availability updates, and articles about newly released free tiers and credits. Listings are checked and stale endpoints can be marked deprecated or removed, so the directory is meant to be a maintained starting point rather than a static list of links.
Free AI API is useful for developers, students, indie hackers, educators, and teams evaluating AI capabilities before committing to a paid provider.
