# Kyma API > Kyma API is an LLM API gateway that routes one key to 106 models and publishes measured uptime per model. One endpoint, 106 models, 70 language/reasoning, 12 retrieval, 10 image, 3 video, 10 audio. OpenAI- and Anthropic-SDK compatible, multi-route redundancy with automatic failover. Pay per token for language models, per image for image generation, per second or per clip for video, and per character / minute / track / generation for audio. Cached prompt input is billed at each model's own cached-input rate, published beside its input rate. $0.50 free credit on signup, no card required — it spends on the free tier (44 of 106 models: everything billed per token (language, embedding, reranking) at or under $3/M output and $0.50/M input, plus everything billed per unit at or under $0.01 per billing unit), not on the whole catalogue.
