Promptoll is the AI gateway for developers who use more than one model. Connect once and reach every major LLM — GPT-5.5, Claude, Gemini, DeepSeek and more — through a single OpenAI-compatible API. No new SDKs, no rewrites: point your existing OpenAI client at Promptoll and switch models with a single line. WHY PROMPTOLL • One API, every model. Drop-in OpenAI compatibility means your existing code just works. • One key for everything. Generate an API key and call any model — no separate accounts, no scattered billing. • Pay as you go. Top up a balance and pay only for what you use. No subscriptions, no minimums. • Full cost transparency. Every request is logged with model, token count, latency and exact spend. • Smart routing. Optionally let the gateway auto-route to the cheapest equivalent model and cut your bill. IN THE APP • Dashboard — your balance, request volume, token usage and spend at a glance. • Chat — talk to any model from your phone and switch instantly with the model picker. • API Keys — create, name and revoke keys in seconds. • Logs — inspect every request with a full model, latency and cost breakdown. • Settings — manage your account, language and routing preferences. BUILT FOR DEVELOPERS Promptoll speaks the OpenAI Chat Completions format, so it works out of the box with the OpenAI SDK, the Vercel AI SDK, LangChain and any OpenAI-compatible client. Use the same base URL and key across web, mobile and server. Start free, add credit when you need it, and keep every token accounted for.
