POST /v1/check · mode reference

mode:ai_overview

Google Search results with the AI Overview block expanded. Returns the rendered AIO text and every URL Google attributes the AI answer to.

Why this matters for GEO

Google's AI Overview now sits at the top of the SERP for ~40% of informational queries. Surfacing in the AIO is the new featured-snippet — and the references Google lists are the new gold standard for "what content is winning AI search". This mode gives you the rendered AIO + the reference graph in a single sub-5-second call.

Pricing

$0.05 per call — the cheapest live mode. 100% refund on upstream failure.

SLA

Target 99% success rate, <5s p95 latency. SERP-grade reliability.

Notes

  • No AI Overview rendered for this query? The response still 200s with mentioned: false and an empty citations array — Google doesn't render an AIO for every query. Pair with mode:bing_copilot to cover both engines' AI surfaces.
  • fan_out / brand_entities are always empty in this mode — those signals don't exist on the AIO surface. Use chatgpt_live or gemini_live for fan-out signals.
