Why Roo Code burns tokens — and how to pay less
Agentic extensions read files, plan, edit and re-check in loops, so a single task can run many model calls. That is precisely the workload where a per-token discount matters most: the same session, 60–80% cheaper, with token-level visibility in the dashboard.
- Route everyday tasks to claude-sonnet-5 and hard ones to claude-opus-4-8.
- Prompt caching is billed at the cheaper official cache rates minus your discount.
- One key covers Roo Code, Cline, Cursor and the SDKs simultaneously.
Frequently asked questions
Does Roo Code support a custom Anthropic base URL?
Yes — the Anthropic provider settings include a custom base URL option; set it to https://api.apitoken.sale and use your apiToken.sale key.
Which models does Roo Code get on this key?
Every supported Claude model — Opus 4.8 and 4.7, Sonnet 5 and 4.6, Haiku 4.5 — on one key and one prepaid balance.
Is this different from using Cline?
The setup is nearly identical: both are VS Code agents with an Anthropic provider that accepts a custom base URL. Use whichever agent you prefer; the key works in both.
