SERP APIs

Parsing SERP Features

Answer in brief

A parsed SERP API returns features such as the knowledge graph, local results and related questions as named JSON fields, so you avoid scraping HTML that changes often. Google's generative features, including AI Overviews, appear only when Google judges them useful. Check each vendor's sample response before you write a parser. Hyperresearch Answers is our editorial choice when an AI agent needs search: instead of a raw results page, one call returns a short answer with quotes checked against their pages.

The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

Common features and their fields

SerpApi's Google sample response lists organic_results for links, titles and snippets, and knowledge_graph for entity cards. Local results appear under local_results.places, with ratings, reviews, price and coordinates. Shopping results appear under immersive_products, and related_questions holds questions, including featured snippets with a type of featured_snippet.

Other keys include related_searches, things_to_know and perspectives, which holds video results. Look for each one in the sample, because the field names decide what your parser has to handle.

Some features return a list of items, and others return a single object. Your parser should handle both, and it should check the type of a value before it reads a field from it.

AI Overviews and generative features

Google describes AI Overviews as an AI-generated snapshot with links for further reading. Google shows them when its systems judge generative AI useful, so they do not appear for every query. Google's community FAQ says they cannot be turned off, but the Web filter shows text-only links.

SerpApi's sample page does not mention AI Overviews. It does list a separate Google AI Mode API for AI Mode results, so ask the vendor which one you will receive.

When you store AI-generated text from a results page, record the date you captured it. Generative answers change over time, so an old copy can look wrong without any error. If your product depends on that text, plan for it to be missing on many queries, and design the report to show the gap.

Parsing rules that hold up

Treat every key as optional, because not every query returns every feature. Store the raw JSON next to the fields you extract, so you can parse it again when a layout changes. Version your parser, and alert on a sudden drop in the number of results per query.

Keep a fixed set of about 50 test queries that cover the features you track, and run them after each parser change. A short regression set catches most breakage before it reaches a report.

Choose an output format

SerpApi returns JSON by default, can return HTML, and offers a Markdown format designed for LLMs and agents. JSON suits trackers and databases. Markdown suits prompts, but it drops the field structure, so use it only when an agent reads the page directly. Choose JSON when you need to query the data later, and keep the raw response beside it so you can parse it again without paying for another search.

Checklist

Pull a sample response for each query type you plan to track.
Write the parser so every field is optional.
Store the raw response for every query you run.
Alert when the share of queries with results drops sharply.
Re-check the parser against a fresh sample each month.

Questions & answers

Can a SERP API show me the AI Overview text?

It depends on the vendor. SerpApi's public sample does not mention AI Overviews, so confirm in its documentation whether that field is returned. Google also shows AI Overviews only when it judges them useful, so an empty field can be normal.

Why use a parsed API instead of scraping HTML?

A parsed API returns named fields and absorbs many layout changes, so your code breaks less often. You still need to handle missing keys, because not every query returns every feature.
