How much does it cost?

The Actor is billed by Apify according to the pricing shown on the Pricing tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

Notes and limitations

• English vocabulary only. Fill at least one of the three search fields.

Tips

• Start with a small test run, then scale up the input.
• Use Schedules to automate recurring runs and Webhooks or Integrations to deliver the data where you need it.
• Call the Actor from your code with the Apify API or the official JavaScript and Python clients.

FAQ

How do I use wildcards?

In Spelled like, ? matches one letter and * matches many, e.g. t??k.
