The purpose of this API parameter is to adapt our caching layer based on your necessities:
  • If you are targetting a URL that changes very often and response time is not critical for you, a small value will work better.
  • If you are targetting a URL that doesn't change too much or you want to maximize cache hits, getting faster response time, a higher value works better.
The value provided will reflected as x-cache-ttl as part of the response headers.
