Nexa is an independent AI gateway for developers. Use one compatible API to connect the models and coding tools you already work with, then switch models without rebuilding your integration.

Yes. Nexa follows familiar OpenAI-compatible request formats. Set your base URL, add your Nexa key, and choose a supported model from the catalog.

Nexa is designed for Codex, Claude Code, DeepSeek, and your own applications. Endpoint support depends on the selected model and protocol.

Add credit to your workspace and pay for the balance tokens your requests use. Each model has a clear multiplier so you can compare cost before you send.
