As a drop-in API — the same model at an OpenAI-compatible endpoint. Two settings:

  1. Create a workspace API key in the Overblast console — usage bills that workspace's AI tokens, at the prices on this page.
  2. Point your base URL at https://brain.deployd.network/ai/v1. Chat completions with streaming, embeddings, /images, /audio/transcriptions and /videos.
curl https://brain.deployd.network/ai/v1/chat/completions \
  -H "Authorization: Bearer ob_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    "messages": [{ "role": "user", "content": "Hello" }]
