How calls are charged
Call any service at /v1/services/<name>/ with your Usage key, sending whatever that API expects. Fixed-price services cost the listed amount per successful call. Pay-per-call services set their own price each time; Usage pays them and charges you that price plus 6%, up to the limit shown. If a call fails, you aren't charged.
