No markup games.

§ 06 — The deal
Pay for tokens.
Nothing else.
Every model is billed at the vendor's public list price, per token, from a prepaid balance you top up by card or crypto. 37 chat and image models across 14 providers — and the meter only runs when you call one.
* Credit never expires. When your balance runs out, requests stop — they never overdraft.
§ 06b — Questions
Fair questions, straight answers.
What is RouterPlex?
RouterPlex is an AI gateway that gives you one API key to call 37 models from 14 providers — including Claude, GPT, and Gemini — through OpenAI- and Anthropic-compatible endpoints, with usage-based pricing and hard per-key spend limits.
How does RouterPlex pricing work?
You pay per token at the vendor's published list price with 0% markup and no fee on top-ups. Top up from $5 by card or crypto — no subscription required, and your balance never goes negative. Optional monthly plans (Plex Lite, Pro, Max) include bonus credits worth more than their price plus higher rate limits.
If the markup is 0%, how does RouterPlex make money?
Two ways: optional monthly plans that sell higher rate limits (their bonus credits are still worth more than the plan costs), and the float on prepaid balances. Token prices stay at vendor list price — we don't make money on your usage.
Is RouterPlex compatible with the OpenAI SDK?
Yes. Point OpenAI clients at api.routerplex.com/v1. RouterPlex also supports the Anthropic SDK and /v1/messages format at api.routerplex.com; both formats reach every chat model.
How is RouterPlex different from OpenRouter or LiteLLM?
RouterPlex is a hosted, ready-to-use gateway: one key, vendor list prices with 0% fee on top-ups (OpenRouter charges 5.5% by card), per-key budgets, and a prepaid balance that never goes negative — no proxy to self-host and no lock-in. Read the full OpenRouter comparison →
