Helix/Docs
Framework preview — structure only
Build on Helix in one call.
An OpenAI-compatible API for 100+ models with smart routing, one key and one bill. Point your existing SDK at the Helix base URL — everything else stays the same.
Quickstart
Three steps: get a key, set the base URL, send a request. The model: "auto" value lets Helix route to optimal supply; pin a specific model any time.
# 1 · set your key & the Helix base URL
$ export HELIX_KEY="hlx_live_..."
$ export OPENAI_BASE_URL="https://api.helixnetwork.app/v1"
# 2 · call it exactly like OpenAI
$ curl $OPENAI_BASE_URL/chat/completions \
-H "Authorization: Bearer $HELIX_KEY" \
-d '{"model":"auto","messages":[{"role":"user","content":"hi"}]}'
