This file has been split into one page per resource, matching how every platform referenced in ../changelog.md organizes its own API reference — and so each page could carry its own verified request/response shapes instead of one long file mixing several.
The content that used to live on this page (base URL api.voicematrix.net/v1, call_abc123-style IDs, a flat error shape) was never accurate — see changelog.md for what was wrong and why this rewrite happened.
