Why Developers Choose MuAPI
We abstract away the complexity of handling multiple generation platforms, so you can focus entirely on building your application.
Lower-Cost Access to Leading Models
MuAPI gives you lower-cost access to leading AI models through a flexible credit-based system. Compared with official APIs and marketplaces, many models are priced around 30% lower, while selected high-demand models can offer 60–70% savings.
One API for 250+ AI Models
Access video, image, audio, and LLM models through one unified API. Switch between Veo, Flux, Seedance, Runway, Claude, GPT, Gemini, and more without rebuilding your backend.
99% Availability. 24/7 Monitoring
MuAPI keeps high-volume AI generation workflows moving with monitored API availability, around-the-clock task monitoring, async task tracking, webhook callbacks, and smart fallback routing across all supported models.
Webhook & Polling Support
Provide a webhook URL to be notified instantly when media is ready, or use standard status polling based on your architectural needs. Both patterns are supported out of the box.
Simple AI API Integration
Integrate once and access leading models across video, image, audio, and LLMs. With clear documentation, unified task flows, and consistent API patterns, your team can switch models by changing a single parameter.
Robust Data Security
Secure API authentication, encrypted requests, and controlled task handling help protect your prompts, assets, and generation results across production workflows.
What technical teams value about MuAPI
Trusted by the builders powering the next generation of AI-native applications.
“We've already deployed our infrastructure using MuAPI. Handling Webhook callbacks instead of long polling for Veo and Kling generation saves us massive server costs.”
Frequently Asked Questions
Everything you need to know about integrating and billing with MuAPI.
MuAPI is a unified AI API platform that lets developers access leading video, image, audio, and LLM models through one consistent API. Instead of integrating different providers one by one, you can use MuAPI to connect to multiple top-tier AI models with a simpler workflow, clearer documentation, and competitive pricing — often around 30% lower than official pricing, with some high-demand models offering even greater savings.
MuAPI supports a wide range of leading AI models across multiple categories including video, image, audio, and LLMs. For video generation, we support models such as Seedance 2.0, Veo 3, Kling, and more. For image generation, we support Flux, Midjourney, DALL-E 3, and other advanced image models. For audio, we support Suno, ElevenLabs, and other audio APIs. For LLMs, we support Claude, GPT, Gemini, and more. You can browse the full model list on the playground.
We offer a flexible pay-as-you-go pricing model using credits, so you only pay for what you use. Different models may use different billing units, such as per image, per second, per video, or per million tokens. There are no monthly subscription fees for access. You can view detailed costs for each model in our pricing page and documentation.
MuAPI's pricing is transparent and listed publicly. For larger top-ups, MuAPI provides bonus credits. For example, higher-tier top-ups include additional bonus credits, which makes the effective usage cost lower than the listed price. Check the billing page for current bonus tiers.
Each model page includes a playground where you can test the model before integrating the API. New users also receive free credits for testing, so you can try different models and workflows before starting formal development.
With our unified API, you can integrate multiple AI models in minutes using a single standardized interface. Integrate once and access leading models across video, image, audio, and LLMs. Your team can switch models by changing a single model_id parameter instead of rebuilding the backend.
You can find the API documentation at muapi.ai/docs. The documentation includes API endpoints, request examples, parameters, webhook callback usage, response formats, and model-specific integration details.
No. Failed tasks are not charged. If a generation task fails, MuAPI will not charge credits for that failed task. This helps developers test and run production workloads with more confidence, without paying for unsuccessful generations.
Yes! All assets generated through MuAPI (images, videos, audio, text) are yours to use for both personal and commercial projects. You retain full ownership of the content you create.
Yes. MuAPI is designed to support production-level use cases and commercial workflows. We monitor model availability and task performance 24/7, and we continuously optimize routing and backend resources to improve stability. When issues occur, our team works to identify and resolve them as quickly as possible.
No. MuAPI credits do not expire. Your credits will remain in your account and can be used at any time.
MuAPI does not set a strict concurrency limit on running tasks. For new request submissions, the default limit is designed to support most users and production use cases. If you receive a 429 rate limit error, you can contact our support team to discuss increasing your rate limits based on your usage needs.
