The headless OneOver

Everything the OneOver platform does — frontier chat and image models today, with video endpoints on the way — available to your code through one REST API and one key. Build on our infrastructure and inherit our data policy. Team seats and pooled credits? See OneOver for Business.

POST /api-v1-chat

curl https://api.oneover.com/api-v1-chat \
  -H "Authorization: Bearer oo_live_YOUR_KEY" \
  -d '{
    "model": "gpt-5.6-sol",   # or claude, gemini, grok…
    "messages": [{ "role": "user", "content": "Hello" }]
  }'

# Switching models is a one-field change.
# Same key, same credits, same invoice.

Every model, one endpoint

Chat, images, and usage across GPT, Claude, Gemini, Grok, Flux, and more — a single REST API.

Streaming built in

Server-sent events for chat, with credits and balance reported on the final event.

Pooled credits underneath

API calls spend from the same shared balance as your team’s seats — one ledger, one invoice.
