  CometAPI is an AI API aggregator that consolidates access to 500+ models
  from multiple providers (OpenAI, Anthropic, Google, xAI, DeepSeek,
  Alibaba, and more) behind a single OpenAI-compatible REST surface. It
  supports chat completions, embeddings, image generation, text-to-video
  and image-to-video, speech synthesis, and audio transcription. CometAPI
  positions itself as a drop-in replacement for the OpenAI SDK (changing
  only the base URL and key), with pay-as-you-go pricing reportedly 20-40%
  cheaper than direct vendor rates, sub-400ms median latency, and 99.9%
  service availability.

      OpenAI-compatible REST API exposing chat completions, embeddings,
      image generation, video generation, speech synthesis, and audio
      transcription across hundreds of upstream models. Authentication
      uses a bearer token, and the `model` field on each request selects
      the upstream provider (e.g. gpt-5.5, claude-4-7-opus,
      gemini-2.5-pro, deepseek-v4, sora, veo, kling, whisper).
    x-features:
      - One bearer-token credential for 500+ models
      - OpenAI SDK drop-in (only base URL and key change)
      - Chat, embeddings, images, video, speech, and transcription
      - Streaming chat completions
      - Tool/function calling support
      - Pay-as-you-go billing with no monthly fees
      - Real-time usage analytics and per-key budget controls
      - Sub-400ms median latency, 99.9% availability
    x-use-cases:
      - Replacing single-vendor SDKs in SaaS apps
      - Cross-vendor model evaluation and A/B testing
      - Cost consolidation across an enterprise AI portfolio
      - Multi-modal pipelines combining text, image, video, and audio models
      - Internal model routers and prompt-experimentation tooling
