Query an AI answer engine for GEO/AEO visibility.
Synchronous passthrough to the upstream Oxylabs Realtime endpoint (POST /v1/queries). Pick an AI answer engine with source and send the parameters that source expects; the request body is passed through unchanged. The response returns the AI-generated answer text and the cited source URLs, letting you track how a brand or product is surfaced and cited across AI answers. AI sources (chatgpt, gemini, perplexity) take ~40–60s and Google-type sources ~4–8s, so use a client timeout of at least 90s.
Passthrough body. source selects the AI answer engine; the remaining fields are the parameters that source expects (see per-source notes on each property). Additional upstream parameters are passed through as-is.
