Metrics for up to 60 keywords in one call: monthly Google search volume, the last 12 months, the trend (month, quarter, year), CPC, ad competition, keyword difficulty (0–100) and search intent. For new keyword ideas around a topic use keyword_research instead.
Billing: 10¢ per call (1–60 keywords). Not billed when nothing comes back or the call fails; the same call again within 24h is free. On the no-account server, a caller without credit gets one data call a day free.
Inputs:
keywords — 1–60 keywords.
country — ISO code (US, CA, GB, AU, NZ, IE, IN, SG, ZA, AE, DE, AT, CH, FR, ES, IT, NL, SE, FI, MX, BR); default US.
Returns { country, keywords: [{keyword, search_volume, monthly_searches: [{month, volume}], trend_pct: {monthly, quarterly, yearly}, cpc_usd, competition, keyword_difficulty, intent}], not_found, cached, charged_cents }. not_found lists keywords with no data (too rare or new).
