**APIs profiled:** 2

Kudosity is an Australian business messaging platform — formerly Burst SMS / TransmitSMS — running two live public REST APIs on two hosts. The Transmit Message API (v2) covers SMS, MMS, WhatsApp and RCS with API-managed webhooks and sender registration; the Transmit SMS API (v1) carries contacts, lists, dedicated virtual numbers, keywords, email-to-SMS and all reporting. Both share one account, one set of senders and one bill. Both ship public OpenAPI documents. What makes Kudosity unusual for its size is the agent-native surface layered on top: a hosted MCP server whose tools/list answers without credentials, llms.txt on both the docs and marketing hosts with per-section fan-out, and five published agent integrations — a Claude Code plugin, a GitHub Copilot extension, a Gemini CLI extension, an OpenClaw channel plugin and an SMS GitHub Action — all open source in a public GitHub organization. RCS is in beta; there is no voice product, no sandbox and no idempotency key.
