Inspect Keyword
inspect_keyword(keyword: string)Search volume, difficulty, CPC and intent for one keyword.
How big and how hard one keyword is: monthly search volume, CPC, paid competition, organic difficulty and search intent, from the search index. It doesn't fetch Google's live results; inspect_serp does that, so the two never disagree about who ranks.

Recommended Follow-up Tools
Provenance Guarantees & Error Handling
ReliabilityEvery fact emitted by Vouched includes source_class, method, observed_at ISO timestamp, and a published confidence score. LLM agents can inspect these citations to distinguish first-party verified facts (e.g. Search Console) from modeled competitor estimates.
Billing & API Keys
Paid market data, on Pro and Team. A call typically costs about $0.014 per call of market data, so Pro's included $4 covers roughly 285 calls. Self-hosted, it uses your own DataForSEO key and bills you directly, with nothing added. See pricing for what each tool costs.
