One API. SMS, voice, Telegram, email, and Slack, normalized into a single event format, with carrier compliance handled through official channels.
Buy a verified phone number or set up a Telegram bot in one call. Provider accounts and configurations are managed for you.
Every inbound message — whether SMS, Telegram, voice, email, or Slack — arrives at your endpoint in the same shape. Write one handler, reach every channel.
Production-grade webhooks with HMAC signatures and retries. Or skip the public URL and stream events directly to your laptop.
Brand and campaign registration with The Campaign Registry for 10DLC. Sender identity validated through each provider. CTIA Messaging Principles enforced.
The same human texting your number and DM'ing your bot stitches into one contact. Conversations follow the person, not the channel.
A 10-line Python demo gets you replying to live messages. Drop down to raw HTTP whenever you need to.
The example echoes any incoming message back to the sender, whether they reached your agent over SMS, Telegram, voice, email, or Slack.
Same handler. Same shape. No SDK to memorize, no provider-specific quirks.

To activate AgentRelay over SMS, text START to our number. We'll reply with a 6-digit verification code. The inbound text itself is your express opt-in — no form, no pre-checked box, no surprises.
About this number. It's used only for AgentRelay's own account communications — 2FA verification, security alerts, account notifications, and support replies for accounts created at agentrelay.in. Customers who use the AgentRelay API to message their own end-users register their own phone numbers and 10DLC campaigns separately.
By texting START (or any keyword) to the number above, you expressly
consent to receive SMS messages from AgentRelay at the originating number.
