What derouter.ai does
derouter.ai is a paid API service for accessing Claude and GPT models through a single account and API key. The site presents it as a drop-in replacement for the Anthropic and OpenAI APIs, with the same official model versions and no request rewriting, model swapping, or other changes to the payload.
The product is built for developers who want token-based access to frontier models with transparent pricing, as well as for operators who may want to resell access through sub-keys or referrals. The documentation highlights quick-start API integration, reseller tooling, and referral commissions, while the pricing page lists fixed rates for text and image generation.
Core features
No request modification
The site says requests are forwarded verbatim, with no prompt rewriting, injected instructions, model swapping, or post-processing, and no added system prompt beyond a standard client identity header.
Published token-based pricing
Pricing is presented as fixed and transparent in USD per 1M tokens, with separate input, output, cache read, cache write, and official I/O rates where applicable.
Image generation pricing
The pricing page includes image generation billing for GPT Image 2, with price determined by generated size tier rather than the low/medium/high quality setting.
Developer and reseller docs
Documentation includes an API integration guide plus reseller materials for sub-keys, markups, client management, and portal setup.
Worldwide direct access
The site says the service is available worldwide, supports direct access, and allows sign-up by email with crypto or bank card payment options.
Common use cases
Integrating frontier models into apps
Use derouter.ai when you want to connect an existing application to Claude or GPT without changing away from familiar OpenAI- or Anthropic-compatible client patterns.
CLI-based coding assistants
Use the service for Claude Code or Codex CLI workflows when you need a compatible base URL or custom provider setup rather than a separate model-specific account.
Predictable usage billing
Use the published fixed token rates and cache/image pricing when you need predictable usage-based billing for product experiments or internal tools.
Reselling API access
Use the reseller materials if you operate a portal or agency model and want to create sub-keys, set markups, and manage downstream clients.
Referral-driven distribution
Use the referral program if you want to share the service and earn tiered commissions on referred API consumption.
