The published artifact set on APIs.io includes API documentation, an API reference, authentication docs, and rate-limit docs.

Places outbound PSTN and SIP voice calls programmatically and runs an authored iX Hello flow on the call. Three result-delivery modes — synchronous (connection held to a 30 second gateway timeout), polling, and signed webhook callbacks on call.answered / call.failed / call.completed. Optional answering-machine detection gates whether a flow session is created at all. Organization-scoped bearer API keys; two operations, initiate and get status.
