What is GPTProto?
GPTProto is an all-in-one AI API platform that gives you access to over 200 models—including text, image, video, and audio—through a single, unified endpoint. Instead of juggling separate accounts, keys, and billing for OpenAI, Google, Anthropic, and others, you get one API key that works across every model. The pay-as-you-go pricing is up to 80% cheaper than buying directly from providers, with no monthly subscriptions, no hidden fees, and free fallback routing. Built for developers, startups, and enterprises who want to ship AI features fast without the integration overhead.
What are the features of GPTProto?
- One Unified API: Call any model—GPT, Claude, Gemini, Kling, Seedance, and more—using the same OpenAI-compatible request format. No SDK upgrades when new models launch.
- Below-Cost Pricing: GPTProto pools global AI compute and passes volume discounts to you. Most models are 20–60% cheaper than official list prices, with zero platform fees.
- Auto-Routing & Failover: Smart scheduling picks the cheapest, fastest route first. If a provider goes down, traffic automatically reroutes to a backup model—keeping your uptime high.
- Multi-Key Budget Control: Generate unlimited API keys, set credit caps per key, and track spend by team or project. Full usage breakdowns help you stay on budget.
- Generous Recharge Bonuses: The more you top up, the more bonus credit you earn automatically. Stack rewards as you scale.
- 99%+ Success Rate: Over 6 million API calls every 12 hours with built-in retry and failover. Enterprise-grade reliability without the enterprise price tag.
What are the use cases of GPTProto?
- AI Writing, Support & Coding Tools: Let users pick their preferred model—Claude, GPT, or Gemini—without your engineers maintaining separate API integrations.
- AI Agent & Workflow Platforms: Chain cheap models for routing, powerful models for reasoning, and fast models for output—all through one swappable API layer.
- Enterprise AI Gateway: Unify company-wide AI usage. See who's calling which model, track spend per team, and govern access from a single control plane.
- Traditional Software Going AI: Integrate AI as easily as any REST API. Test multiple models side-by-side before committing—no ML expertise required.
- Multimodal Apps: Pipe text from GPT into Midjourney or Kling video through the same API—no separate accounts or billing needed.
