**APIs profiled:** 3

Subspace was a real-time network-as-a-service platform delivering a dedicated, performance-optimized global network for latency-sensitive applications — WebRTC, VoIP/SIP calling, video conferencing, multiplayer gaming, and fintech. Its Product API provisions three services: PacketAccelerator (no-code global internet acceleration), SIPTeleport (SIP/VoIP call-quality improvement), and WebRTC-CDN (instant global WebRTC acceleration with ICE server configuration). The REST API uses resource-oriented URLs and JSON responses, versioned at v1, authenticated with OAuth2 client-credentials issuing 24-hour JWT bearer tokens via Auth0, and ships six first-party OpenAPI client SDKs. The company was a Bloomberg Beta portfolio company; its marketing site remains live while the API, identity, and status hosts have wound down operationally.
