Example use cases
AI answer visibility after product launch
“We just launched a new feature — can you check whether 'Loom' (loom.com) is showing up in AI-generated answers for keywords like ['async video messaging', 'screen recording tool', 'video collaboration'] in the US in English? I want a full deep scan.”
Competitive brand monitoring in new market
“I want to know if our brand 'Pipedrive' (pipedrive.com) is appearing in AI answers and SERP results in Germany — check keywords like ['CRM software', 'sales pipeline tool', 'verkaufs-CRM'] in German (de) for country de.”
Track rank changes week-over-week
“Run a deep SERP and AI answer check for 'Webflow' (webflow.com) in the US for keywords ['no-code website builder', 'visual web design tool', 'cms for designers'] in English, and compare it against last week's snapshot so I can see if we went up or down in AI visibility.”
Technical details
Endpoint
POSThttps://api.exepal.com/v1/serp-ai-monitor/deep?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deep, combined view of both traditional SERP rankings and AI-generated answer visibility for a brand or domain, especially with change-tracking over time. It is particularly valuable for brands running AI-era SEO programs, tracking whether they appear in LLM-cited results or AI overviews, and measuring rank drift. The /deep tier is appropriate when thoroughness and historical comparison matter more than speed or cost. Prefer it over lighter monitoring endpoints when you need per-keyword breakdown with snapshot diffing.
Side effects
- Missing required fields (brand or keywords) returns a 400 validation error
- Invalid country or language codes return a 422 error
- Keywords array exceeding tier cap results in truncation or rejection
- previousSnapshot format mismatch causes change-tracking to fail or return no deltas
- Payment failure via x402/USDC results in 402 Payment Required before any data is returned
- No AI answer data available for a keyword returns empty or null results for that keyword
