About This Site
One key, every modality—run text, images, video, and code through GPT, Claude, Gemini, Sora, Veo, and Banana from a single endpoint. Two channels, your call: route everyday traffic through the value tier to keep costs down, and flip critical workloads to the official tier when stability matters. OnAPI is a one-stop AI model API gateway that gives developers a single key to handle text, image, video, and code across every major frontier model—GPT, Claude, Gemini, Sora, Veo, Banana, and more. Turn models into products. Ship ideas. Two channels, you're in charge: send everyday traffic to the high-performance value tier and stretch every dollar; flip mission-critical calls to the official tier, backed by real paid keys hitting the providers directly. No reselling tricks, no smoke and mirrors, no substituting cheap models for premium ones—just a reliable safety net when it counts. Fully OpenAI-compatible. Change one line—your base_url—and you're done. Works out of the box with the OpenAI SDK, LangChain, Claude Code, Cursor, Cline, and Cherry Studio. No international credit card required, no juggling bills across half a dozen vendors. Pay with Alipay, WeChat Pay, or crypto, billed by usage, with credits that never expire.

Fraud detection with bot, AI agent and risky user detection for web apps.
ShieldLabs combines deterministic rules and AI to detect bots, AI agents and risky users on every visit to a website or web app. It is fraud detection and prevention with traffic quality scoring: a JavaScript snippet collects 300+ device and network risk signals and cross-checks them, so VPNs, proxies, Tor, anti-detect browsers and browser automation show up as named signals.
Every visitor, user, device and IP address gets a 0-100 risk score, with 99.9% identification accuracy. Multi-accounting, account sharing, account takeover and impossible travel are detected directly, out of the box, each with a Medium or High confidence level. An AI copilot turns the collected data into summaries, investigations and ready-to-run actions, and traffic quality is scored by source, channel and campaign.
ShieldLabs brings enterprise-level functionality without enterprise pricing to SaaS, AI products, fintech, e-commerce, iGaming, crypto, marketplaces and media. Setup takes about five minutes, results arrive through the API and webhooks, and the free plan includes 5,000 identifications.
