Good Questions.

What does the price comparison API return?

Product listings with seller, price and source links. Our test also returned ratings and product identifiers.

Does the lowest listed price mean the same product?

The $57.00 result was a Mac version. Business versions appeared too. The response supplies offer data; an identical-SKU match was not established.

Does this include checkout prices or price history?

This example is one shopping snapshot. Taxes, final checkout totals, stock and historical prices were not tested.

When is a direct search account a better fit?

SerpApi includes 250 free monthly searches and paid search plans. A direct account can fit regular use of its Google Shopping API; TaskFuel uses your existing balance for a request within a larger task.

What did the shopping search cost?

The example cost $0.004 on 6 November 2026. Your agent shows the price for your own request before it pays.

Do I need a separate provider account?

No. Your agent pays from your TaskFuel balance, so there is nothing else to sign up for.

Your agent can do things it couldn’t this morning.
