One API for leading AI image, video, audio and text generation models, with OpenAI-compatible requests and pay-as-you-go pricing.
HiAPI is a developer-first API platform that gives teams one key for leading image, video, audio and text generation models. Instead of integrating a different SDK, billing flow and account for every provider, developers send OpenAI-compatible requests to a single endpoint and receive results through a unified async task API. The platform covers text-to-image and image editing, text-to-video and image-to-video, music and voice generation, and large language models. Current catalog highlights include GPT Image 2.6, Seedream 5.0 Pro, Seedance 2.0, Kling 3.0, MiniMax H3 and DeepSeek V4.1 Flash, with new models added as they launch. Every model shares the same authentication, request format and response shape, so switching a model is a parameter change rather than a new integration. For product teams, HiAPI removes the operational overhead of multi-provider setups: one balance, transparent per-model pricing, usage visibility and no monthly minimum. Developers can test prompts in the browser playground before writing code, then copy the exact request from public documentation and an OpenAPI spec. Async jobs are polled through a single /v1/tasks interface, which keeps long-running video and audio work simple to manage. Typical users are AI product teams, automation builders, agencies and creators shipping image or video features. Common workflows include generating product visuals, building short-form video ads, generating voiceovers and prototyping agent tools. A remote MCP endpoint also lets Claude, Codex and other MCP clients call generation models directly. Pay-as-you-go top-ups start small, so teams can evaluate several models before committing to a production budget.
