All our API plans include a different number of calls. What are they exactly?
Other calls or meta calls — any API requests that do not contain the content of an icon (a user receives icon metadata such as its name, styles, category, etc.). They are addressed to search engines (receiving metadata).
Download calls — direct download of icons in sizes/formats other than free ones (a user receives content or metadata with content). They are actual downloads (receiving content).
Free requests — icons in PNG format ≤100x100 px; animated icons in GIF format. They are not counted as downloads.
When a user searches and views an icon, it would be counted as an other/meta call if the icon is only previewed (<100x100 px) but not added to the project. However, it would be considered a download call if the user requests a high-quality asset and adds it to their project.
For example, the Startup API plan ($250/mo) includes 5000 prepaid requests to search engines and 1000 prepaid monthly downloads. Each extra download costs $0.05, other calls are $0.001.
