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.
AskUI
What is AskUI?
AskUI lets delivery teams automate real devices in plain English. You write a task as a Markdown file in Git, an AI agent runs it on desktop, web, mobile, or hardware displays, and returns a verdict plus a screenshot for every step.
Traditional test automation depends on DOM selectors and brittle scripts that break when UIs change. AskUI tests what is rendered on screen, including canvas apps, Citrix sessions, and QNX HMIs controlled through HDMI capture with nothing installed on the target. The trade-off is sales-led pricing quoted per concurrent agent after a scoping call, not self-serve monthly plans.
QA teams replace manual regression on legacy SAP portals and vendor RFQ systems. Automotive manufacturers run HMI regression across infotainment fleets. Operations teams generate audit evidence with screenshot-backed run reports from scheduled agent jobs.
