How it works
This is the same guide whether you're deciding to sign up or you're already a subscriber trying to find a setting. Every step below refers to the exact menu item you'll see once you're signed in.
Credit in the sidebar. Buy a one-time pack (card, GrabPay, or PayNow) or subscribe to Plus for 15% off every request. Your balance gates usage — no balance, no surprise bill.API keys → Create key. The plaintext key is shown once — store it in your own secrets manager.Connect a client in the sidebar for the exact base URL for your account.# the only change on your side: export ANTHROPIC_BASE_URL=https://messages.router.ecoino.my export ANTHROPIC_API_KEY=sk-ec-•••••••••• # everything else works unchanged $ claude "refactor the auth module"
One Anthropic-compatible endpoint in front of Claude, GPT, and more. You send the same request shape you already know; the router decides which model actually serves it, meters every token, and bills it against your prepaid balance.
ANTHROPIC_BASE_URL to your router endpoint (shown under Connect a client) and ANTHROPIC_API_KEY to your key. No SDK change, no code rewrite.A prepaid balance only protects you after it's gone — by the time you're at $0, the damage is already spent. The circuit breaker watches your spend velocity and error rate in real time and trips before that happens: it pauses new requests automatically, then recovers on its own once traffic looks normal again.
Every "should we switch to a cheaper model" decision is usually a guess based on a benchmark that isn't your workload. Shadow evaluation forks a sample of your real traffic to one or two challenger models, scores each against the model you actually used, and shows you the quality, cost, and latency trade-off — as evidence, not a guess. Your customers never see the challenger's answer; only the model you chose responds.
Two ready-made multi-model workflows, hosted and metered by the platform, invocable with the API key you already have — no orchestration code to write or run yourself.
Everything above is billed from one prepaid balance — no separate invoices per feature, no allowance to track. Add credit whenever you like; a plan just changes the rate or unlocks a feature, never a hidden minimum.
