Transparent, scalable, usage-based pricing

REST Credits

REST Credits are requests made to our servers to retrieve data via the REST protocol. Each time you fetch data, the number of requests varies based on the endpoint used and the amount of data requested.

  • For example, if the limit query parameter is used, each 100 data points returned is counted as one request.
  • If the limit query parameter is not used or not available, each API call you make is counted as one request.

Pricing is tiered based on your daily usage:

  • Calculated per 1,000 calls
  • Tiers reset daily
  • Rates decrease as usage increases
  • Usage covered by the committed-usage plan quota is counted

Higher volume users automatically benefit from lower rates. See the table below for specific pricing tiers.
