On our side, sitelinks, knowledge panel, People Also Ask and related searches arrive with the AI Overview endpoint, not with the plain organic call — one request returns all four alongside the overview and the results.

Surface

We cover two surfaces: web search, and web search with the AI Overview. That is fewer than most providers here, and it is a choice rather than a roadmap gap — one surface measured continuously and published in public is worth more than twenty nobody checks.

Honestly

When Scrapingdog is the better choice

Scrapingdog is cheap and its credits do not expire, which suits irregular work well. Its Google response carries fewer blocks than ours — no knowledge panel, no People Also Ask, no sitelinks in our measurement.

Difference

What you get here that you do not there

A dedicated AI Overview endpoint returning Google's answer and the sources it credits, which Scrapingdog does not document. And a public measurement record: 4,185 queries run weekly through the same endpoint, with 50.8% carrying an overview as of 2026-W36.

Nobody else in this table publishes what their API returns. Ours is written out in full.
