you.bot
you.bot is a multi-model API marketplace that puts video, image, music, speech and chat models from OpenAI, Anthropic, Google, ByteDance, Kling, MiniMax and others behind one REST endpoint and one prepaid credit balance. Developers change a single modelId to switch providers, while published per-model rates show how far each price sits below the provider's standard rate.
Kinovi
Kinovi is a pay-as-you-go platform that exposes 36+ video, image and audio models from 10 providers through one REST API and one browser studio. Seedance 2.5, Wan 3.0, GPT Image 2, Midjourney V8 and Suno all draw on a single prepaid credit balance, with per-second and per-image rates published on every model page before you generate.
Hyper3D
Hyper3D is Deemos Tech's AI 3D generation platform, built around the Rodin model. Give it a text prompt, a product photo, a sketch or a multi-view set and it returns a textured, quad-topology 3D asset in under a minute. Bounding-box, voxel and point-cloud controls steer the result, and exports drop straight into Blender, Unity or Unreal.
FastRouter
FastRouter is a unified LLM gateway that gives developers one OpenAI-compatible API for 200+ models from providers such as OpenAI, Anthropic, Google, and xAI. It adds automatic model routing, fallbacks, caching, spend caps, role-based access, guardrails, and per-request observability, while passing provider token prices through with no markup on any plan, including the free tier.
RouteMarket AI
RouteMarket AI is a unified creative marketplace for AI models, workflows, provider routing, and developer APIs. It brings 125+ image, video, audio, text, and 3D models from 23+ providers into one workspace, with a model playground, reusable workflows, an OpenAI-compatible API, and BYOK key support. A free Personal tier unlocks every model, and new accounts earn free daily login credits.
Segmind
Segmind is a serverless AI model platform and gateway for image, video, audio and voice generation. It exposes 550+ models from Alibaba, Kling, OpenAI, Google, Black Forest Labs and ElevenLabs through a single REST API, plus PixelFlow, a visual canvas that chains models into reusable workflows and republishes them as production endpoints. Billing is pay-as-you-go credits, monthly subscriptions or dedicated GPUs.
Hailuo AI
Hailuo AI is MiniMax's consumer studio for AI video, images and audio. Its MiniMax H3 model takes text, image, audio and video references and returns 2K clips up to ten seconds, with multi-shot generation, first-and-last frame control, extension, relighting and upscaling. Hailuo Agent chains those renders into longer stories, while Hailuo 2.3, Veo 3.1 and Sora 2.0 stay selectable.
GPTProto
GPTProto is a global AI API aggregation platform that unifies 200-plus leading models, including Sora, Veo, Kling, Seedance, GPT-5.6, Claude, and Gemini, behind one OpenAI-style key and one shared balance.
