Opper Multimodal & Realtime

Everything beyond text: generate and edit media, run OCR, store and reuse files, send images and PDFs to a model, and run two-way voice over a WebSocket. Same gateway, same Authorization: Bearer $OPPER_API_KEY, same Control Plane governance and tracing as the text endpoints — just different surfaces.

For text generation, chat, structured output, migration from another gateway, and server-side tools (opper:web_search and friends), use the opper-api skill — those ride the compat chat endpoints and stay there.

The live v3 spec is the source of truth

Default workflow for any question this skill doesn't immediately answer — endpoint, parameter, field, provider knob — grep the spec. Don't guess, don't invent endpoints or model ids. The spec is unauthenticated and definitive:

curl -s https://api.opper.ai/v3/openapi.yaml   # YAML, easier to grep
curl -s https://api.opper.ai/v3/openapi.json   # JSON
