The Actor uses pay-per-event pricing: a small fee for each run start, a fee per article, video or comment returned in a list, and a higher fee for each full article, each counts lookup, each Channels profile and each Channels video detail, because each needs its own lookup, and separate fees for mini programs, comments and account subjects.

Worked examples:

• 100 search results on a paid plan: $0.015 + 100 × $0.005 = $0.515.
• 100 full articles on the Bronze plan: $0.015 + 100 × $0.0184 = $1.855. On Gold: $0.015 + 100 × $0.015 = $1.515.
• 100 comments of one video: $0.015 + 100 × $0.005 = $0.515.
• 100 comments under one article: $0.015 + 100 × $0.003 = $0.315.
• One keyword, 25 mini programs: 10 × $0.015 + 25 × $0.014 = $0.50. A second keyword adds another $0.15 plus $0.014 per result.
• 3 accounts' registered companies: $0.015 + 3 × $0.45 = $1.365.
• One Channels profile on Gold and above: $0.015 + $0.015 = $0.03. Each further profile adds only $0.015.
• 40 videos of a collection (two pages): $0.015 + 40 × $0.005 = $0.215.
• One account's custom menu on Gold and above: $0.015 + $0.015 = $0.03. Each further account adds only $0.015.
• 3 accounts, 30 articles in total: 3 × $0.015 + 30 × $0.005 = $0.195, if all three accounts are reached.

A collection, channel or account that returns nothing (not found, no live replays, no custom menu, or the request did not complete) is not charged. If three such inputs in a row come back empty after a request that could have been billed to us, or those requests add up to about $0.10 in one run, the run stops with the remaining inputs reported as ended early. An account the source rejects without any charge (for example an account ID that does not exist) is skipped and does not count toward the three, except that once a run has had more than a handful of such rejections each further one counts like an empty one. A run whose very first request fails ends with a message to retry later and charges nothing. After a restart, an account menu already delivered is not asked again; a collection or channel already delivered may be asked again but is not charged twice and does not count.

Nothing is charged once maxResults is reached, and you never pay for more than maxResults items.

When article search uses its fallback

If the usual article search cannot answer before any result is delivered, search mode switches to a fallback search on its own, page by page until maxResults is reached or no more results come (up to about 40 articles per page). The fallback is billed for every page it answers, whatever is on it, so every fallback page you get costs at least about $0.16. The extra start fees are worked out from the prices of your own run, so the page total stays about the same if the run-start price changes (at a lower start price, more start fees make up the same amount). At today's prices:

For example, maxResults 20 costs $0.015 + 3 × $0.015 + 20 × $0.005 = $0.16 instead of $0.115. A fallback page is only requested when your spending limit can pay for its dearest outcome (the message gives the amount); if it cannot, the run stops with a message saying so and nothing charged. If the usual search was billed for failed attempts first, the first fallback page also covers those, with a few more start fees (up to about $0.06). A second page is only requested after a full first page, and the search stops at the first page with no new article. The fallback has no time filter: with publishTime set it returns the newest articles and drops the older ones, and only the articles kept count as results. Fallback results may lack readCount. The run log says when the fallback was used. When the usual search works, the fallback is never used.

On the free Apify plan you get 2 free trial runs of this Actor with your own input, up to 10 results each, and nothing is charged; after that, runs return a stored sample dataset (a real result of the prefilled input). Use any paid Apify plan for full runs.
