OnAPI
What is OnAPI?
OnAPI is a unified API gateway that lets developers call GPT, Claude, Gemini, Sora, Veo, and Google's Nano Banana image model through a single key. Swap your SDK base URL to OnAPI's endpoint, plug in an OnAPI key, and keep the rest of your integration unchanged.
The gateway speaks OpenAI-compatible and Anthropic-compatible protocols, so chat completions, Anthropic messages, streaming, function calling, and long-context requests work without a rewrite. OnAPI says new upstream models typically appear within 24 hours of release.
Two routing channels share the same account. The economy channel bills at a 1:1 rate multiplier for everyday volume. The official channel routes through paid keys tied directly to provider accounts at a 1:7.5 multiplier when you need a straighter path to upstream APIs.
OnAPI is aimed at builders shipping AI products, especially where direct provider billing is inconvenient. Top-ups run through Alipay, WeChat, USDT, and USDC. Account balance does not expire, and the site states there is no minimum spend.
The service runs on the open-source New API project (based on One API), which handles model aggregation and cross-format conversion between provider APIs.
Gradio
What is Gradio?
Gradio lets you wrap any Python function or ML model in a web demo with a few lines of code. This open-source Python library ships 40-plus UI components for images, audio, video, chat, dataframes, and JSON, then serves the interface locally or deploys it permanently to Hugging Face Spaces. Run pip install gradio, define your function, and call demo.launch() to get a browser UI at localhost:7860.
Streamlit and Dash also build Python web apps, but Gradio is built specifically for model demos: gr.Interface wraps a single prediction function, gr.ChatInterface handles chatbots, and gr.Blocks supports multi-step layouts like the Automatic1111 Stable Diffusion UI. The share=True flag creates a temporary public URL in seconds, which is hard to replicate without setting up your own hosting.
ML engineers, researchers, and hobbyists use Gradio to prototype interfaces before production. It requires Python 3.10 or higher, needs no JavaScript or CSS knowledge, and is free and open source with optional free hosting on Hugging Face Spaces.
