Why these are free

Every tool is a thin front end over one API call. Running them costs us a fraction of a cent, and it is the most honest demonstration we can give: if the data quality is not good enough here, it will not be good enough in your pipeline either.

Each page shows what the equivalent API call charged, live. On a cache hit it reads zero, because cache hits cost zero.

When to move to the API

  • You need more than a handful of results at a time.
  • You want the data in your own system rather than in a text file.
  • You need to know when something changes rather than what it is right now.
  • You need platforms these tools do not cover yet.
