ethereal is a gateway to Claude models (Opus, Sonnet, Haiku) through a single OpenAI-compatible endpoint. Plug in any familiar SDK or CLI, change the base_url — and you’re ready. Pay via SBP or crypto, no cards and no VPN, with transparent per-token billing.

No subscription

Pay only for the tokens you use. No monthly charges and no auto-renewals — your balance never expires.

Transparent billing

Each request is charged at the model’s rate (input/output). Full breakdown in your dashboard.

Payments from Russia

SBP or cryptocurrency — no VPN and no foreign cards.

OpenAI compatibility

A drop-in replacement: the same request format as OpenAI Chat Completions. Works with popular SDKs and dev tools.

​
Who it’s for

  • Developers using Claude in code, the CLI, and agents (Claude Code, Cursor, Cline, Aider…).
