Compare

Side-by-side rankings for your brand vs. up to 10 competitors, plus a co-mention graph.

Overview

Like /v1/rankings but for one primary brand against a competitor set, with a coMentions graph: for each pair of brands, how many model answers name both, surfacing who AI frames you alongside.

Reference

POST/v1/compare

$0.01 to $0.06/model · billed per model queried, so all 5 models = $0.20. Pass models to query fewer.

Parameters

`query`required	string	The query to compare the brand and competitors on.
`brand`required	string	Your brand — ranked alongside the competitors.
`competitors`required	string[]	Competitor brand/domain names (up to 10) to rank against your brand.
`models`optional	array of enum (chatgpt \| claude \| perplexity \| gemini \| google_ai_overview)	Optional model subset. Omit to query the default surfaces (chatgpt, perplexity, gemini). Pass ["perplexity"] or ["perplexity","claude"] when the user names specific surfaces or wants to reduce cost. The full set is chatgpt, claude, perplexity, gemini, google_ai_overview — to query all of them, set fullSweep instead of listing them.
`fullSweep`optional	boolean	Query all five AI surfaces instead of the three default ones, adding claude and google_ai_overview. Costs more per call. Use it when the user wants complete cross-model coverage, is comparing surfaces against each other, or asks specifically about Claude or Google AI Overviews. Ignored when models is given.
