CometAPI is a unified API platform that gives developers one key and one OpenAI-compatible endpoint to access 500+ AI models for text, image, and video work.
About
CometAPI is a unified API aggregation platform that lets developers call more than 500 AI models from providers such as OpenAI, Anthropic, and Google using a single API key and a single billing account. The problem it addresses is provider sprawl: teams that use models from several vendors normally juggle separate credentials, invoices, and endpoint formats, which slows development and complicates cost tracking.
The service works by exposing an OpenAI-compatible endpoint. A developer points an existing OpenAI SDK at CometAPI's base URL, supplies a CometAPI key, and can then swap between models by changing only the model name in a request. The platform handles authentication, routing, usage analytics, and consolidated billing across text, image, and video models. Billing is pay-as-you-go with no monthly fee, and the company states that customer prices are set below official vendor rates. CometAPI also offers business plans with team governance features and publishes developer documentation, a model catalog, and a changelog on its official site.
Key Features
Pricing & Fees
- Pricing: Usage-based, pay-as-you-go with no monthly fee. Examples from the pricing page include DeepSeek V4.1 Flash at $0.12 per 1M tokens (official $0.15) and Claude Haiku 5.5 at $0.08 per 1M tokens (official $0.10). Video models such as Wan 3.0 Prime are billed per second ($0.0544/sec vs. official $0.068/sec).
- Free trial: Signup requires no credit card and includes test credits for trying models.
- Stated performance: The site reports 99.9% service uptime and under 400 ms average response time; these are vendor-claimed figures.
- Security and privacy: The vendor states customer data is never used for model training, with encrypted transit and user-controlled request logging.
- Support channels: Email support, a Discord community, and a public GitHub organization with SDKs and examples.
Who It's For
CometAPI is aimed at developers and engineering teams building AI features into products without wanting to manage relationships with multiple model providers. Typical users include full-stack developers prototyping chat or generation features, AI engineers running production text, image, or video workloads, and startup teams that want consolidated billing and spending visibility. It also suits automation builders who connect AI models to workflow tools such as n8n or Zapier, and businesses in sectors like software, finance, retail, healthcare, and customer service that the vendor names in its solutions pages.
