Voygr Calls API

Programmatic outbound phone calls executed by an AI voice agent. Submit a task either as a plain-language brief or as a structured intent plus slots (inquiry, info_gathering, issue_resolution, booking, cancellation); the agent places the call, works through phone trees and hold, conducts the conversation in one of 13 languages, and returns a structured outcome with a full transcript. Calls are asynchronous — poll the call until it reaches a terminal state, or cursor-poll an SSE-formatted event feed for live progress and mid-call questions. A post-call merged transcript is rebuilt from the dual-channel recording. OpenAPI 3.1.0, 13 operations, X-API-Key auth, US destinations only, AI disclosure and recording notice on every call.

Where this information came from

This is an independent, third-party profile of Voygr Calls API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
