Unified access
One API key for everything
Replace separate OpenAI, Anthropic, and Google keys with a single credential. Switch models in one line of code — no re-auth, no migration.
Cost advantage
Permanently 20–40% cheaper
CometAPI prices are set below official vendor rates on every model. Pay-as-you-go — no monthly subscription, no hidden fees, no minimum spend.
Portability
Zero vendor lock-in
Swap from GPT-5 to Claude to Gemini instantly. If a provider changes pricing or goes down, you stay running — just change the model name.
Observability
Usage analytics & cost control
Real-time dashboard showing spend, latency, and call volume. Set budget alerts before you overspend. Compare models side-by-side.
Developer speed
Prototype to production in hours
Playground, Postman collection, SDK, and sample projects included. OpenAI-compatible format means your existing code works out of the box.
Trust & security
Enterprise-grade privacy
Your data is never used to train models. Secure key management, encrypted transit, and request logging you control.

Currently, I use other platforms for images (Nano Banana Pro) and for LLMs. I'd like to migrate my entire setup to CometAPI. Your pricing for the LLM 'gemini-3-pro-preview-thinking' is excellent. I'd like to consolidate all my traffic (LLM + image generation) with you.

As developers, we really enjoy communicating with you and your support team, and we would not want to switch to alternative API services.

CometAPI is an AI platform providing advanced AI APIs designed for developers and businesses. It offers powerful AI APIs for text generation, music creation, video generation and more.
CometAPI offers a free trial, allowing you to access their services. Once you set up your account, you can immediately get a free API token to start using the AI models without any upfront costs.
Yes — CometAPI offers complete API documentation and developer guides. Our API docs include step‑by‑step integration instructions, configuration examples, authentication details, usage limits and best practices to help developers quickly integrate CometAPI into their applications.
Our competitive pricing comes from our unique business model and technical infrastructure. We have developed an intelligent routing system that optimizes every request, purchase API credits in bulk from multiple providers, and use a multi-region server architecture to secure better rates while maintaining high service reliability.
As an API intermediary, CometAPI does not store or log any prompts, requests, or responses that pass through our system. Users should anonymize sensitive data before submitting requests. Note that upstream AI providers have their own data policies.
We support over 500 models, including LLMs, image generation models, video generation models, such as Sora 2, Gemini 3.x, GPT-5, Grok 4.2, and Nano Banana series.
