usage limit not clear from documentation

[NGeorgescu]

Hi,

There are a number of unofficial APIs written for DDGS, reliant on the information here. Some experimentation has revealed that it seems page counts are what seems to be tracked, for instance, in the likelihood of a 202 with a "DDG.deep.anomalyDetectionBlock" result. But the actual usage limit has users guessing.

Is there any guidance on what the usage limits are for using https://links.duckduckgo.com/d.js for results?
