People Also Ask is one of the most informationally dense SERP features in 2026. For SEO, content, and RAG teams, it is a direct line into the intent structure around a keyword. The best People Also Ask API returns not just the top questions but the follow up questions that appear when you click on them, because Google expands the tree dynamically. We ranked the top four providers on PAA depth, answer snippet completeness, price, and agent integration. The winner helps content and SEO teams build question driven content at scale without scraping Google directly.
Scavio is the best People Also Ask API in 2026 for most use cases. It returns the full PAA tree with follow up questions and answer snippets alongside the organic SERP, starting at thirty dollars a month for seven thousand searches.

Why Scavio Wins
- Scavio returns the full People Also Ask tree with follow up questions and answer snippets, not just the top level list, which is what content teams actually need for question driven articles.
- PAA data arrives in the same response as organic search, so a single API call powers both the main article brief and the FAQ section without additional round trips.
- Structured question and answer fields feed directly into content briefs, CMS generators, and RAG pipelines, saving content teams hours of manual extraction per article cycle.
- Credit pricing keeps PAA research cheap for agencies, which lets strategists produce briefs for hundreds of keywords in a week without blowing a content operations budget.
- Native MCP support means editors can query PAA trees live from Claude Code or Cursor while drafting, turning PAA into an always on content assistant instead of a one off export.
