One key, every Claude model, live in minutes.
Point your existing Anthropic SDK or Claude Code at a single base URL and reach the full line-up — Opus, Sonnet, Haiku and Fable. Every request is metered, every dollar is visible, and spend ceilings are enforced at the proxy rather than printed on a marketing page.
Description
Direct API access hands you an uncapped meter and an invoice you learn about afterwards. This sits in front of it — same models, same request format, but with the ceilings and the receipts you need to leave an agent running unattended.
- --one-endpoint
- Opus 5, Sonnet 5, Haiku 4.5 and Fable 5 all answer on the same base URL. Choose a model per request; you never provision, rotate or juggle more than a single key.
- --agent-ready
- Streaming passes straight through, so Claude Code sessions, coding agents and multi-hour reasoning jobs behave exactly as they do upstream — no adapters, no proxy-shaped edge cases.
- --hard-ceilings
- Two windows run at once: a rolling five-hour limit and a weekly one. Both are checked before a request is forwarded, so a runaway loop cannot drain the account overnight.
- --full-audit
- Every call is written to your log with model, token counts and cost. The dashboard shows exactly how much of each window is left — no month-end guesswork.
Models
Addressed by their usual model IDs. Paid plans reach all of them — your plan sets the spend ceiling, never which model you may call.
Quickstart
Sign up with an email address and confirm the six-digit code. The dashboard opens straight away — no card, no sales call.
Issue a key from the dashboard. One key covers every model, and you can rotate it the moment you suspect it leaked. Treat it like a password — anyone holding it can spend your balance.
Export two environment variables and carry on. Nothing else in your setup changes.

FAQ
Which SDKs and tools work?
/v1/messages format — the official
SDKs, the Claude Code CLI, and the editor extensions built on them. Change the base URL and the
key; leave the rest alone.
