When you submit a query to Trestle, the HTTP status code from our APIs determines whether it is billable.
Your account will be billed whenever you receive a 200 response (regardless of whether or not the request found a match). Your account will not be billed if you receive an error response, such as a 429 or a 501. All 4XX and 5XX queries are exempt from billing.
If you would like to view your usage data, follow the instructions here. If you need assistance with billing or usage tracking, please reach out to us at support@trestleiq.com.
