Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys falcon-h1 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (falcon-h1 below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"falcon-h1","messages":[{"role":"user","content":"Hello"}]}'
