CometAPI
The Unified API for 500+ AI Models
CometAPI is an AI infrastructure platform that provides a single API key for accessing more than 500 AI models from providers including OpenAI, Anthropic, Google, xAI and MiniMax. It replaces separate provider credentials with one OpenAI-compatible interface, consolidating authentication, billing and endpoints so teams can switch models without maintaining multiple accounts or integrations.
The platform supports text, image, video, voice and reasoning workloads, with a model comparison tool, usage analytics, budget alerts and a playground for testing prompts across models. Integrations include Claude Code, Codex, Gemini, Cline, Coze, Dify, n8n and Zapier. Security documentation covers TLS 1.2+ encryption in transit, API key management, data retention policies and a public status page; the Trust Center notes that formal certifications have not yet been initiated.
CometAPI is aimed at developers, SaaS teams, enterprises, agencies and automation builders. It uses a prepaid, pay-as-you-go credit model with no monthly subscription, and offers free trial credits at signup without requiring a credit card.
