Create Gemini Omni voice resources, character resources, and Flash Preview or multimodal text-to-video tasks through RunAPI. Use when the user asks an agent to create or manage Gemini Omni audio voices, character resources, or video. Default to the RunAPI CLI for one-off calls; use SDKs only when integrating RunAPI into an app or backend.

The skill document
Gemini on RunAPI
Use Gemini contents at https://runapi.ai with generateContent or
streamGenerateContent as the primary protocol.
Primary protocol recipe
Authenticate
Set GEMINI_API_KEY to a RunAPI API key and the Gemini client base URL to
https://runapi.ai. Raw requests send the key with x-goog-api-key.
Send request
curl -X POST \
"https://runapi.ai/v1beta/models/gemini-3.6-flash:streamGenerateContent" \
-H "x-goog-api-key: $GEMINI_API_KEY" \
-H "Content-Type: application/json" \
-d '{"contents":[{"role":"user","parts":[{"text":"Summarize this review."}]}]}'
Use generateContent for a synchronous response and streamGenerateContent
for long output. Add inline media, function declarations, grounding, structured
output, or reasoning only when the current RunAPI contract verifies the exact
model and request shape.
Verify result
Require candidate content, terminal finishReason, and usageMetadata. A
stream is complete only after the terminal candidate and Usage; an HTTP 2xx
without both is incomplete.
Stop boundaries
Correct a rejected shape once using the structured error. Retry transport once only before any candidate or Usage and when replay is safe. Record a terminal error and stop without changing model or protocol.
Compatibility protocols
Load compatibility protocols only when an existing client requires OpenAI-compatible Chat Completions.
