Transparent, scalable, usage-based pricing

API Calls

API calls are requests made to our servers to retrieve data. Each time you fetch data, send us a subscribe message, or perform any action using our API, it counts as one call.

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.

Daily Usage Tier

50,001 - 100,000 calls
$0.40 per 1,000 calls

$0.20 per 1,000 calls
