CometAPI

Managing separate API keys for OpenAI, Anthropic, Google, and a dozen other AI providers adds up to real overhead: separate billing dashboards, rate limits to track, credentials to rotate, and codebases tied to specific provider formats. CometAPI cuts through that by giving you one API key and one endpoint that routes to 500+ AI models across every major provider.

The integration lift is minimal. CometAPI uses an OpenAI-compatible format, so you change the base URL and API key in your existing code and everything keeps working. That applies to text generation across Claude, GPT, Gemini, and others, but also image generators, video synthesis tools, and voice models, all routed through the same interface.

Pricing is where the practical case becomes clear. Every model on the platform costs at least 20% below the provider's official rate, with no monthly subscription, no minimum spend, and no credit expiry. The real-time dashboard shows spend, latency, and request volume across all model usage in one place. When multiple models are running in production, knowing which one is actually burning through budget takes seconds rather than logging into separate accounts.

The platform integrates with automation tools including n8n, Make, Zapier, and Dify, and works with Claude Code for AI development workflows. Budget alerts, request logging you control, and a data policy that explicitly bars using your requests for model training round out the feature set.

This is a developer tool. You need to be comfortable reading API docs and debugging HTTP calls. The people who get the most value from it are either running multiple AI providers already or building applications where swapping models without restructuring the integration matters. That flexibility is a real operational benefit when a provider has downtime or a model underperforms on a specific task.

One thing to test before committing: streaming responses and function calling can behave inconsistently across providers. CometAPI passes requests through to underlying provider infrastructure, so provider-level quirks can surface in your application depending on which model you're using.

CometAPI has 10,000 active developers on the platform, 99.9% uptime across its infrastructure, and sub-400ms average response latency. The company was founded in 2023 and is based in Hong Kong. New accounts receive test credits at signup with no credit card required.
