View live system status

You load USD into your wallet. Each request is metered by our upstream and charged at the model's per-million-token price — every token (input, output, cache) counts the same, including a small fixed system overhead per request. Your dashboard shows the exact billed tokens for every call. When your balance runs out, requests return a clear insufficient-balance error, never a surprise bill.

First top-up: deposit $1, get $100 in credit. Bonus credit is added automatically when your payment is confirmed and applies to your first deposit only.

NayaPay · Binance Pay. Payments are matched by transaction ID and credited as soon as they're confirmed.

Yes. Set ANTHROPIC_BASE_URL to our endpoint and ANTHROPIC_AUTH_TOKEN to your key, then run claude. The official Anthropic SDKs work the same way — just change the base URL.

Yes. Every key can have its own USD spend cap, expiry date and model allow-list. When a key hits its cap it pauses while your other keys keep running.

No. We log request metadata for billing (model, token counts, latency, cost) — not prompt or response content.
