Output
Returns a JSON analysis containing the overlapping items found between two search result sets, including matched entries, intersection metrics, and any warnings about data quality. The result includes a service_id, analysis_json with the comparison details, and an evidence_scope indicator.
Example use cases
SEO keyword cannibalization check
“I have search results for two similar keywords — 'content marketing strategy' and 'content marketing tips' — can you compare them and show me which pages appear in both so I know if they're competing with each other?”
Research deduplication across queries
“I ran two different research searches and got back two lists of results. Can you find which sources appear in both lists so I can remove the duplicates before I compile my report?”
Competitor SERP overlap analysis
“Here are the top 20 results for 'project management software' and the top 20 for 'task management tools' — compare them and tell me which domains show up in both result sets and how much overlap there is.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/search_result_overlap_compare/invokeWhen to prefer
Use this endpoint when you need to programmatically compare two search result sets and identify shared or overlapping entries. Prefer this over manual deduplication when dealing with structured search result JSON from any source. Best suited for SEO analysis, research aggregation, or any workflow where understanding the intersection of two query result sets is valuable.
Side effects
- Invalid or malformed JSON in request_json field causes processing failure
- Empty or too-short input (below minLength of 2) rejected
- Oversized input exceeding 65536 character limit returns error
- Misformatted search result structure yields incomplete analysis
- Caller-supplied data not verified — results depend entirely on input quality
