Get API KeyHow It Works
Three steps to agent texting
Get an API key
Sign up to receive your key and start sending immediately. Coming soon.
Send a message
Make a single REST call with your key, a phone number, and a message body.
Read replies
Your agent checks an inbox endpoint and receives replies for two-way conversations.
Features
What you get
Low-volume enforcement
Rate limits and daily caps are built in. This is not a mass-messaging platform.
Consent-first posture
You must obtain consent from every recipient. The API is designed around that expectation.
Single Toll-Free sender
All messages originate from one registered Toll-Free number for transparency and trust.
Two-way inbox
Recipients can reply, and your agent picks up those replies from a simple inbox endpoint.
Simple REST API
One endpoint to send, one to read. JSON in, JSON out. No SDKs required.
Use Cases
What developers build
Agent alerts to yourself
Have your AI agent text you when a deploy finishes, a threshold is hit, or something needs attention.
Opted-in check-ins
Your agent sends brief status updates to known, consented numbers—teammates, clients, or family.
Workflow confirmations
Ask a human to confirm an action: "Reply YES to approve." Two-way messaging makes it seamless.
Trust & Compliance
Responsible messaging by default
Consent required. Every recipient must opt in before receiving a message.
No cold outreach. This API is not built for unsolicited messaging of any kind.
Low volume enforced. Built-in rate limits and daily caps prevent abuse.
Opt-out handling. Recipients can reply STOP at any time to cease messages.
