Are these AI APIs really free?

Yes. Each listing is a genuinely free way to use hosted AI models — a permanent free tier, a one-time credit that needs no credit card, or free model access through an aggregator. Every free-tier limit is verified against the provider's own pricing or docs page, and 0 of the 0 providers need no credit card at all.

Which free AI API is best for testing without a credit card?

For quick prototyping with no card, always-free tiers like Groq, Cloudflare Workers AI, Google AI Studio and Cerebras give you generous daily limits on open models. Use the “No credit card” filter to see every option, and the modality tabs to narrow to text, image, audio or embedding models.

How is this list kept up to date?

An AI research agent re-checks each provider's free tier against its own documentation on a schedule. Any change to a limit, a credit-card requirement or the free-tier type is held for human review before it publishes, and each provider shows when it was last verified.
