How to Monitor Published Competitor Prices with Apify
A repeatable way to compare prices without confusing visible product metadata with checkout totals or private inventory.
Start with the documented example, check live Apify pricing, then decide whether to run it.
Try the competitor price monitor →1. Start with a known public product fixture
The PAL monitor has a preconfigured synthetic example in its README. Inspect the example before starting a run; even an example run can consume Apify usage credits.
2. Record the first baseline
Enter supported public HTTPS product URLs and choose a stable monitor ID. The first successful observation establishes a baseline; it cannot yet report a real historical price change.
3. Choose a meaningful comparison
Optional reference prices help compare a published competitor price with an amount you already know. Match the exact source URL and currency; no currency conversion is implied.
4. Run a second check when needed
Reuse the same monitor ID to generate change flags and inspect the CSV or JSON result. An unchanged price is useful evidence, but a successful repeated check may still be billed.
5. Review limits and cost
The tool reads static Product JSON-LD or supported product-type Open Graph metadata. It cannot confirm checkout stock, promotions, tax or shipping totals. Set a run budget before enabling a schedule.
Keep the first test small
Use an authorized example, inspect the dataset, check whether the Actor meets your workflow, and review any charges. If it does not work on your site, do not interpret missing data as a real stock or price change.
