Crun AI

Crun AI is a developer-first AI API aggregation platform that consolidates 100+ leading AI models across video, image, and audio generation into one unified API—eliminating the need for multiple vendor accounts, separate API keys, and complex billing by providing one catalog, one balance, and one task shape for all models. Unlike traditional API aggregators that only forward chat requests to LLMs, Crun covers video generation (Sora 2, Veo 3.1, Seedance 2.5, Wan 3.0, Kling, Runway), image generation (Nano Banana 2.1, Seedream 5.0 Pro, Flux.1, GPT Image, Midjourney), audio generation (Suno V4, voice, music, ambient sound), and text generation (GPT-5, Claude)—all built for developers who need production-ready, cost-optimized AI integration.

It serves indie developers, startups, product/engineering teams, SaaS platforms, and agent builders who ship with model APIs, offering OpenAI-compatible drop-in replacement (migrate apps with one line of code), interactive playground, Python/JS/cURL examples, real-time usage and log monitoring, and global infrastructure with smart routing for fastest endpoints. With 99.9% uptime, 24.9s average response time, 24/7 support, and #1 data security rating, Crun targets developers who need reliable, scalable, and cost-effective AI integration without vendor fragmentation or subscription lock-ins.

How to Use Crun AI

1. Sign Up & Create API Key: Register at crun.ai, create your account, and generate your personal API key for accessing all 100+ models.
2. Choose a Model: Select from the catalog of 100+ AI models across video, image, and audio based on your application needs.
3. Send Requests: Use the unified API endpoint (https://api.crun.ai/api/v1/client/job/CreateTask) with your API key in the X-API-KEY header and model-specific input fields.
4. Retrieve Results: Poll or wait for task completion, then retrieve generated content (video, image, audio) from the response.
5. Integrate Your App: Seamlessly integrate results into your product or workflow with real-time usage and log monitoring for production tracking.
6. Use Playground (Optional): Test real models in the interactive playground before integration, then use the same model in your app with consistent behavior.
7. Monitor Usage: Check task logs for usage, costs, and status—every response reports what the call cost for transparent billing.
8. Scale to Production: Use the same API key from prototype to production volume with consistent task shape, pricing, and 99.9% uptime across all models.
