Keyword ideas API

Expands a seed keyword into dozens of Google autocomplete probes — alphabet soup (seed + a…z), question words, prepositions and comparison modifiers — and returns the distinct suggestions Google serves, each with the probe that surfaced it and Google's own relevance score. Autocomplete is a plain JSON endpoint, so a run never touches a browser. Duplicate suggestions across probes are delivered (and billed) once.

$0.0002 per delivered keyword, up to 500 keywords per run. Nothing delivered means nothing charged.

• lang (string) — Interface language (hl), e.g. en, it, de.
