AI Video & Image Generation APIs | 01Router

# AI Video & Image Generation APIs | 01Router > One API key for leading AI video and image generation models, with your choice of provider and one credit balance. 01Router (01router.com) is an AI video and image generation API gateway. One API key and one REST API call leading video models (Seedance, Veo, Kling, Wan, MiniMax), image models (Nano Banana, GPT Image, Seedream, Qwen Image), and with the same key audio models (Suno, Gemini TTS) and chat models (GPT, Claude, Gemini, Grok, DeepSeek). Each model is served by one or more upstream providers (fal.ai, Replicate, WaveSpeedAI, KIE AI, APIMart, EvoLink, AtlasCloud, Vercel AI Gateway, OpenRouter): pin one, or let 01Router send each request to the cheapest provider that supports the parameters. Usage is paid per unit from a single credit balance, and failed or timed-out tasks are refunded automatically. ## API documentation for AI - [API documentation index](https://01router.com/docs/llms.txt): Discover endpoint references and live model documentation. - [Full API reference](https://01router.com/docs/llms-full.txt): Request schemas, response fields, copyable examples and live provider-specific model parameters. ## How the API works - Base URL: https://01router.com/api/v1. Authenticate with `Authorization: Bearer <API key>`; keys are created in the dashboard and are billed to the owner's credits. - Video, image and audio are asynchronous: POST /api/v1/generations with `model`, `input` (unified parameters such as prompt, duration, resolution, aspect_ratio, image URLs) and an optional `provider`. The response returns a generation id at once; poll GET /api/v1/generations/{id} until status is `succeeded` or `failed`, then download `outputs`. Output URLs are provider-hosted and may expire. - Chat models use the OpenAI-compatible POST /api/v1/chat/completions (streaming supported), so the official OpenAI SDKs work by changing the base URL. - Quotes are optional and free, with two methods: POST /api/v1/quote returns a
