HiAPI

HiAPI is a unified generative AI model API gateway for developers: with a single API key, it reaches mainstream models across four media types — image, video, audio, and text. It aggregates upstream models from OpenAI, Google, Runway, Suno, and more behind one interface, built around unified async tasks + persistent artifact links, made for developers who want fast multi-model integration.

Core capabilities

• Unified async task interface: one endpoint submits image, video, audio, and text generation tasks, flowing through a queued—processing—archived—success/failed state machine, with idempotency keys preventing duplicate submissions
• Persistent artifact links: with persistent storage enabled, results return long-lived artifact URLs, sparing developers from building their own storage and distribution layer — its core differentiator
• Callbacks instead of polling: automatic callback notifications on task completion replace frequent status polling, better fitting production pipeline orchestration
• Agent-native integration: a remote MCP service (exposing 9 tools), an Agent Skills catalog, and an llms.txt index let agents directly call its image, video, audio, and text capabilities
• OpenAI-compatible text interface: text models work with mainstream OpenAI clients, keeping migration costs low and reusing existing code and ecosystems
• Fast model additions: the catalog lists 92 online models; OpenAI's new image model released September 8 was listed that same week with a launch discount — its follow-up speed is a real strength

Use cases Developers, agent builders, and content tool teams that need to orchestrate multiple media-generation capabilities behind one entry point; bilingual EN/ZH documentation is friendly to Chinese teams. If you want unified billing and authentication, and direct agent connections to multiple multimodal models, it saves the trouble of integrating each vendor's official API one by one — worth a try.

Unique strengths Its edge is not price — connecting directly to official APIs is somewhat cheaper. The real difference is the combination of unified async tasks + persistent artifacts + agent-native integration (MCP/Skills) + bilingual EN/ZH docs, a route closer to kie.ai's media-aggregation credit model than OpenRouter's text-only gateway. Overall, broad multimodal coverage plus a smooth developer experience is its true footing.

Editorial verdict The product is real, the API documentation and model catalog are complete and verifiable, and fast model additions are a demonstrable strength. But the risks must be faced honestly: anonymous operator, WHOIS registration country CN, no ICP filing, domain registered under a year ago, almost no independent reputation, prepaid balances explicitly non-refundable, and opaque upstream licensing and data handling. We therefore position this as a listing with medium-high trust risk — trial with a small top-up first, and never inject a large prepaid balance in one go.
