CometAPI was founded in January 2025 and is headquartered in Sha Tin, Hong Kong. It entered a growing category of unified AI API gateways built to solve a specific problem for developers: juggling separate API keys, billing accounts, and SDKs for every model provider they want to test or use in production.
A single CometAPI credential and endpoint gives access to models across text, image, video, and audio generation from providers including OpenAI, Anthropic, Google, xAI, DeepSeek, and Alibaba, letting a developer swap models by changing one line of code instead of re-authenticating against a new provider. Pricing runs pay-as-you-go per token or per image/second, set around 20% below each provider's own published rate, with no monthly subscription or minimum spend below the enterprise tier.
CometAPI suits developers and small teams building multi-model applications who want to avoid vendor lock-in and rate-shop across providers automatically. New accounts get a free API token to start testing at no cost before moving to paid, usage-based billing; heavy users spending over $3,000/month can contact the company for further discounts.
