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.
JIT.codes
What is JIT.codes?
JIT.codes is a browser-based developer playground where you write, run, and ship code with multiple large language models in one workspace. You pick a model like GLM 4.5, GPT-5, or Claude Sonnet 4.5, chat through an idea, edit the output, preview it live, and deploy without leaving the tab.
Most coding assistants stop at a chat reply. JIT.codes treats each session like a mini IDE with versioning, snapshots, agents, auto-deploy, and a public explore feed where 130,000+ builders share projects. Free accounts get hosting and collaboration tools, while PRO keeps projects private and drops the 10% platform fee on model usage.
It fits indie hackers prototyping a landing page, students testing shaders or games, and small teams who want shared links with real-time edits instead of passing zip files around. You pay provider rates plus a small platform fee on the free tier, or a flat $19 per month on PRO for private workspaces and priority routing.
