Enterprise Messaging & AI APIs, built for production traffic.

OmniNStack is API-first: every capability inside Convergo and Contexa — omnichannel delivery, AI copywriting, risk scoring, evidence logging — is available as a service your engineering team can call directly. API access is provisioned per enterprise engagement.

What You Can Build

Enterprise Messaging APIs

Send and receive across WhatsApp, KakaoTalk, Telegram, SMS, and RCS through one Convergo API, with automated cross-channel failover.

Moderation & Risk Scoring

Call Contexa's context-aware classifier to score user-generated content in real time and route decisions into your own review tools.

Multi-Model AI Gateway

Route inference across public and private LLMs through the same gateway that powers our platform, with zero vendor lock-in.

Getting Started

  • Scoped sandbox: We provision a sandbox environment scoped to your use case for integration testing.
  • Production rollout: Our solutions architects work with your team through go-live, including rate limits, failover, and monitoring setup.
