Inception API through YepAPI
YepAPI provides access to Inception models through a unified API endpoint. Instead of managing a separate Inception API key and billing account, use your single YepAPI key to call any Inception model alongside 261 other AI models from OpenAI, Anthropic, Google, Meta, and more.
All Inception models use the same OpenAI-compatible request format. Switch between models by changing the model parameter — no SDK changes, no code rewrites. Pay per token with no monthly minimums.
