How does API usage scale with depth?

Every question discovered below your maximum depth triggers one further ValueSERP search of its own, so cost scales with the number of questions found, not just the depth setting. A seed that surfaces four questions at level 1 costs one call for the seed plus four calls to expand them at depth 2, and each of those can spawn more at depth 3. The recursion is depth-first, so a single seed can run for a while at higher depths.

Are duplicate questions removed across all my seed keywords?

Only within each seed. The dedupe list resets for every seed keyword, so two seeds that trigger the same PAA question will both contribute a row. Dedupe the question column afterwards if you combine broad, overlapping seeds.

Why is answer_snippet empty for some questions?

The snippet, source URL and source title are only captured when ValueSERP returns the answer as a structured object. When the answer comes back in any other shape, those three columns are left blank while the question itself is still recorded.

What do the level and parent_query columns mean?

Level 1 questions came directly from searching your seed keyword; level 2 questions came from searching a level 1 question, and so on up to the maximum depth of 5. parent_query is the exact query that surfaced the question, letting you rebuild the tree, while original_query is always the seed it descended from.

What does the request delay setting do, and is 0 safe?

It sleeps between recursive API calls, defaulting to 0.5 seconds. Setting 0 fires requests back to back; ValueSERP is a paid API built for volume, but keep a delay if your plan enforces per-second limits. Failed requests are reported in the status line and the run continues with what it has.

Use cases

Building comprehensive FAQ pages Content topic ideation Featured snippet opportunities User intent research Blog post ideas from real questions

Fetches "People Also Ask" questions from the ValueSERP API and recursively re-queries each question to discover deeper layers, up to 5 levels (default 2).

Deduplicates by question text within each seed keyword (duplicates can appear across different seeds), records each question's parent query, and captures answer snippets with source URL and title.

Requests use include_fields=related_questions to keep API payloads small.
