SynOI

Compatibility · 20 tools

Change one env var.
Works with everything you already use.

SynOI speaks the Anthropic Messages API and the OpenAI Chat Completions API. Anything that respects a base-URL env var is already compatible. We test these tools ourselves; the ones below have been verified against the gateway.
