Nyxo

Nyxo gives developers one private API key for five leading models: Claude Fable 5.2 (1M-token context), Claude Opus 5.5, Claude Sonnet 5.5, GPT-6.1 Sol and GPT-6 Astra. Connect Claude Code or OpenCode with one command and start coding. Packs are one-time payments valid for 12 months: $5 gives $40 of usage, $15 gives $150 and $39 gives $500. Every request is billed at the model's per-token price and the balance is visible online. No subscription, no 5-hour or weekly caps. Payment is in USDT on BNB Smart Chain. Nyxo is an independent service, not affiliated with Anthropic or OpenAI.
