GET

Linkbio page

Linkbio (lnk.bio) page

Credit cost	Default: 1 credit How charges are determined Cost is decided per call, not per endpoint: the same operation can cost different amounts depending on what it returns. A call that fails costs 0 credits. A result served from cache costs 0 credits. `default` is the cost when no rule matches. Rules are evaluated in order and the first whose conditions all hold wins. A `when` condition is one of: `param` (the request parameter is true), `outcome` (the classifier's outcome), `empty` / `nonEmpty` (a response field is empty and absent, or a non-empty array or string), `flag` (a response field is exactly true). A cost of `{ perStartedMinute: n, of: [fields] }` is n x max(1, ceil(seconds / 60)), so even a short result bills at least one minute.
Cache support	Use a cached response this old or newer for 0 credits. If none is available, fetch live at the endpoint’s normal price.
Pagination	No explicit pagination metadata in the published contract. Consult the parameters and response fields below.
