How DeRouter Works
Your request is relayed verbatim to official Claude and the response is returned byte-for-byte. Here's how we work — and why you get genuine Claude.
How your request flows
Your request first reaches DeRouter's dispatch layer, which picks a healthy account from the official Claude subscription pool to serve it. If one account hits a rate limit or hiccup, it transparently fails over to another healthy account.
Fully transparent: standard Anthropic in, official bytes out

The account serving your request calls Anthropic through Anthropic's official Claude Code CLI client — the same official channel as running Claude Code locally yourself. Exactly what we add to each request, and the full system prompt and tools, are publicly documented.
See the full Claude Code system prompt & tools →About third-party detection
We go through the Claude Code CLI channel, and the CLI itself does not support forced structured output, so that capability isn't available on our path. It's a channel-capability difference — not a counterfeit, degraded, or rebranded model.
Yes. You get the 100% official Claude model, and responses match official Claude byte-for-byte (see the real round-trip above). Every dimension that measures whether the model is genuinely Claude passes.
