Google Scholar API: what your agent gets.

One cross-index search. Semantic Scholar was rate-limited; citation counts were empty. This example uses arXiv/PubMed metadata rather than Google Scholar results.

  • Search other scholarly indexes through TaskFuel

    2s searches arXiv, PubMed and Semantic Scholar with source labels. This test returned arXiv/PubMed records and reported a Semantic Scholar rate limit.

    $0.006 / tested search

Cross-index paper search, tested.

The response contained six records from arXiv and PubMed. One PubMed title, author list and DOI were cross-checked against the original record.

1. Check the price

Use your TaskFuel API key as TASKFUEL_API_KEY in your terminal or server. Keep it out of browser code. This request checks the price without paying.

The exact request used in the dated example.

2. Run the request

Review amount_usd in the quote. To pay and run, change dryRun to false and add maxAmountUsd with that approved amount inside the same JSON object. Keep the inputs unchanged; this limit applies to one call.

3. Read the result

Read data.items[].source, title, authors, doi and url. limit is per source. data.meta.errors reports partial source failures; citationCount and pdfUrl may be null. This request does not query Google Scholar.

When to use it.

Starting a literature brief

Keep the source index visible.

Your agent can collect titles, authors and original-record links from the returned arXiv/PubMed metadata.

Moving from metadata to text

Use a returned public PDF link.

A public PDF can be read with the separate PDF-to-Markdown tool. This paper-search response itself contains metadata.

Good Questions.

Does this example return Google Scholar results?

No. The TaskFuel example on this page uses 2s to search arXiv and PubMed. For Google Scholar’s own result ordering and citation features, the direct options above query that index.

What does a direct Google Scholar API offer?

SerpApi documents Google Scholar queries, publication-year filters, cited-by searches and version clusters. These are distinct from the cross-index paper search shown here.

Can I use a free tool?

scholarly is free Python software for Google Scholar metadata. You run and maintain it. SerpApi also lists 250 free monthly searches on its direct account plan.

Why were six records returned with a limit of three?

The 2s endpoint applies the limit per source. Three arXiv and three PubMed records came back; the response reported a rate limit for Semantic Scholar.

Does metadata include the full paper?

The tested records included titles, authors, source links and sometimes abstracts or PDF links. Citation counts were empty; full article text was not extracted.

What did the TaskFuel paper search cost?

The separate cross-index example cost $0.006 on 6 November 2026. Your agent shows the price for your own request before it pays.
