# API in One API in One is a unified AI API gateway for website owners and developers who need image, video, music, speech, chat, and AI tool capabilities through one API key and shared credit balance. - Findings24: - Site: - Preços: Freemium - Categorias: API de áudio com IA, Gateways e roteamento de IA, API de imagens com IA ## O que é API in One? API in One is a unified AI API gateway for adding generative and utility AI features to websites and applications. Through one API key and shared credit balance, developers can access supported image, video, music, speech, chat, and AI tool routes instead of managing separate provider credentials in their application workflow. The gateway is available at `https://apiin.one/api/v1`. Chat requests use an OpenAI-compatible endpoint, while image, video, audio, and tool requests generally use asynchronous REST tasks with status polling. Supported routes can expose a task ID immediately and may accept a `callback_url` for webhook-based completion. The product also provides a model catalog and per-request credit costs so developers can compare supported models before calling them. The documented model and tool coverage includes image and video generation, Suno music workflows, ElevenLabs speech synthesis, Gemini chat, background removal, face swap, image upscaling, and video enhancement utilities. ## O que API in One pode fazer? ### Unified model endpoints Access supported image, video, chat, music, speech, and utility models through category-level routes under one API base URL and API key. ### OpenAI-compatible chat Use \`POST /api/v1/chat/completions\` with common OpenAI-style messages and configuration for the documented Gemini chat route; streaming support depends on the selected model. ### Asynchronous media workflows Longer-running image, video, music, speech, and tool requests use task-based processing. Retrieve progress and final outputs through \`GET /api/v1/tasks/\{task\_id\}\`. ### Webhook-capable task handling Supported asynchronous routes can accept a \`callback\_url\`, allowing applications to receive completion events instead of relying only on polling. ### Centralized model and cost comparison The live model catalog lists routed models, endpoint coverage, task mode, and approximate per-request credit costs to help developers compare options before integration. ### Image and video utilities Dedicated tool routes cover image background removal, face swap, image upscaling, video background removal, and video upscaling. ## Casos de uso ### Add generative media to a website A website can call image or video generation routes from a server-side workflow, then poll task status or use a supported webhook to return the completed asset to the user. ### Build conversational product features Applications that need text, reasoning, code, or multimodal chat can use the OpenAI-compatible chat route and select the documented chat model through the request body. ### Create audio production workflows Products can connect music generation, music extension, covers, timestamped lyrics, and text-to-speech routes for audio-related creation flows. ### Automate image cleanup and enhancement Publishing or creative applications can expose background removal, face swap, and image upscale operations as asynchronous utility actions. ### Compare models before implementation Developers evaluating a media feature can review live routes, supported model slugs, task modes, and approximate credit costs before choosing an endpoint. ## Perguntas frequentes ### What is the API base URL? The documented base URL is \`https://apiin.one/api/v1\`. Requests use a bearer token created and managed from the API Keys dashboard. ### Do all requests return immediately? No. Chat completions are synchronous, while most image, video, music, speech, and tool operations are asynchronous. These jobs return a task ID that can be checked through \`GET /api/v1/tasks/\{task\_id\}\`. ### Which capabilities are available? The documented routes cover image and video generation, Gemini chat, Suno music workflows, ElevenLabs speech synthesis, and tools for background removal, face swap, image upscaling, and video upscaling or background removal. Exact model availability is represented in the live catalog. ### How does billing work? API in One uses credits. The model catalog shows approximate per-request costs, and the site offers one-time pay-as-you-go credits as well as monthly and yearly subscription plans. Pay-as-you-go credits are stated to never expire. ### Do I need a separate provider key for each model? No. The site states that one API in One key is used for routed models; the request specifies the supported model name in the JSON body. Provider credentials are kept behind the service's server-side routes. ## Informações rápidas - **Category**: AI API gateway - **Primary users**: Website owners and developers - **API base URL**: https://apiin.one/api/v1 - **Authentication**: Bearer API key beginning with aio\_... - **Workflow**: Synchronous chat plus asynchronous media and tool tasks - **Billing model**: Credit-based pay-as-you-go and subscription plans
