OnAPI vs Nexonauts

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.

Nexonauts is a small developer studio that builds tools and publishes technical writing. The site hosts two main products: Recast, a local-first screen and webcam recorder for Windows with cloud sharing in beta, and Docvia, an MIT-licensed Markdown documentation compiler with React and Svelte renderers.

The Learn section offers side-by-side code walkthroughs, including a six-topic Go concurrency series covering goroutines, channels, select, waitgroups, mutex, and context. Longer standalone guides are available separately.

Nexonauts is run by a solo developer focused on shipping practical tools rather than running a broad marketplace. Contact support at [email protected].
