CometAPI

CometAPI is a unified gateway to more than 500 AI models behind a single key and a single endpoint. The interface is compatible with the OpenAI client libraries, so an application points its base URL at the service, names a model, and reaches text, image, video and voice models from several vendors without separate accounts, separate billing or code changes when the underlying model is swapped. It serves individual developers who want simple usage based access and businesses that need team management, governance and consolidated billing. The platform publishes a model catalog with a comparison view, a quickstart, API status, an enterprise tier and solution guides organized by capability and by industry, covering language and reasoning, conversational AI, vision and image, and video and voice. The pitch is to avoid vendor lock in: one invoice covers every provider, and applications stay stable while the models behind them change. Billing is usage based and published in detail. Official models are token billed at 0.8 times the provider's own list price, with further tiers for monthly volume, while specialty models are billed per image, per clip or per second with no platform fee added. Published examples include a small Anthropic model at $0.08 per million input tokens against $0.1 official, mid sized models from Anthropic, Google and OpenAI at $1.6 per million against $2, and image generation from $0.008 per image. A budget estimator converts a monthly figure between $10 and $5,000 into expected text, image and video capacity. Signup is free, requires no card and includes test credits. The site is localized into more than twenty languages, and an affiliate program is published alongside the developer documentation.
