The directory also allows you to link all 310 API providers, to create one OpenAI- and Claude-compatible gateway then route any model, through any vendor - via a single URL with failover aliases, daily spend caps and per-request compute metering you can audit line by line.
I have not found another project that offers an organized, community-curated system for AI API providers on the same scale as this one.
There is a submission feature so you can submit your favorite AI API providers for free.
