onomeo

onomeo is one OpenAI-compatible API key and a chat page for Claude, GPT and a couple dozen free models.

The big models are pay as you go. You top up once, from $5, and the balance never expires. Nothing renews on its own. $5 is roughly 400 replies from Claude Sonnet 5.5, 110 from Claude Opus 5.5 or 370 from GPT-6.1.

The free models don't need a card. You get 30 calls every 5 hours.

The same key works in SillyTavern, Open WebUI, Cline, Roo Code, Aider, Zed and anything else that takes an OpenAI-compatible endpoint.

onomeo is in public beta. Some features may not work as expected, and we're collecting as much feedback as we can.
