1. What cxntion provides
cxntion provides an SMS bridge service (“Service”) that connects your self-hosted AI agent to a managed SMS number via our platform. We provide the telephony routing, SMS message delivery, and the infrastructure to bridge messages to your agent. We do not provide the AI agent itself.
2. Your account
Public launch access is invite-reviewed. You must provide a valid email address to request or create an account. If access is granted, you are responsible for keeping your API key secure. Do not share your API key. You are responsible for all activity under your account, including messages made through numbers assigned to your agents.
3. Acceptable use
You agree not to use the Service to:
- Bypass invite review, activation gates, account limits, or security controls
- Send unsolicited SMS messages or spam
- Impersonate a human without disclosing the AI nature of the agent to users
- Engage in fraud, harassment, threats, or illegal activity
- Circumvent rate limits, billing, or security controls
- Resell the Service without written agreement
We may suspend or terminate accounts that violate these terms without prior notice.
4. Your agent, your responsibility
You are solely responsible for the behavior, responses, and compliance of your AI agent. cxntion does not review, moderate, or control agent output. You agree to indemnify and hold harmless cxntion from any claims, damages, or liabilities arising from your agent's behavior or responses during messages routed through our Service.
5. Privacy and data handling
Our data practices are described in our Privacy Policy. By using the Service, you acknowledge that SMS messages are stored for conversation context. See our Privacy Policy for details.
6. Phone numbers
Phone numbers provisioned through the Service are leased, not owned. Public beta numbers support SMS messaging. We reserve the right to reclaim or reassign numbers on inactive or terminated accounts after 30 days of inactivity. Numbers are not portable and cannot be transferred outside the Service.
7. SMS messaging
cxntion SMS is a two-way conversational messaging service. Your AI agent replies only when an end user texts first — no unsolicited or marketing messages are sent. Message frequency varies: one agent reply per inbound message. Standard message and data rates may apply.
Reply STOP to opt out of SMS messages from any agent. Reply START to resume. For help, reply HELP or contact hello@cxntion.dev.
SMS message content is stored for up to 90 days to maintain conversation context, then redacted. Billing, routing, and abuse-prevention metadata may remain. You are responsible for ensuring your agent's SMS responses comply with all applicable messaging laws and regulations. See our Privacy Policy for details on data handling.
8. Billing and payment
Planned Pro pricing is shown publicly before self-serve activation is open. During the request-access phase, production-number activation is manual. Paid plans are billed monthly once enabled. Overage beyond included SMS segments is warned first and may be billed at the overage rate for your plan. We may change pricing with 30 days notice. Non-payment may result in suspension of service.
9. Service availability
We aim for high availability but do not guarantee uninterrupted service. The Service depends on third-party infrastructure (Twilio and cloud providers) and may be affected by their outages. We are not liable for damages resulting from service interruptions.
10. Limitation of liability
To the maximum extent permitted by law, cxntion's total liability for any claims arising from or related to the Service is limited to the amount you paid us in the 12 months preceding the claim. We are not liable for indirect, incidental, special, consequential, or punitive damages, including lost profits, lost data, or business interruption.
11. Disclaimer of warranties
The Service is provided “as is” and “as available” without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that messages will be uninterrupted, error-free, or secure.
12. Termination
Either party may terminate at any time. You may delete your account at any time. We may terminate or suspend your account for violation of these terms. Upon termination, your assigned numbers are released and your account data is deleted within 30 days.
13. Changes to terms
We may update these terms. Material changes will be communicated via email at least 30 days in advance. Continued use after changes take effect constitutes acceptance.
14. Governing law
These terms are governed by the laws of the State of Delaware, United States, without regard to conflict of law provisions.
