Collection notes
Only the Search endpoint is modelled, at its searchResults output: $0.005 per call for flash, fast and standard depth, $0.05 for deep. The sourcedAnswer and structured outputs cost $0.001 more per call and are not modelled. Fetch, Research and Extract are separate endpoints. The balance is prepaid in USD; prices are stated without a tax line.
Sources and notes
Each number points to the provider's own sentence, as it appears on the page on the date shown.
Each time you make a successful request to our API endpoints, an amount is subtracted from your account.
How the value follows from the source: One call is one search.
No credit is subtracted when an error occurs, whether that is due to a missing parameter, an internal server error, or because we were unable to find anything relevant to your query.
Search is Linkup’s synchronous web search endpoint, optimized for AI consumption.
Latency by depth: flash under 200 ms, fast about 1 s, standard 1–3 s, deep 5–30 s.
Array of {name, url, content} . Ranked URLs and content snippets for grounding.
