TextKit Launches Cheaper SMS API for Agents
TextKit launched an SMS API for sending and receiving texts in the US and Canada, with SDKs, a CLI, MCP support, sandbox testing, verification, and automated 10DLC registration. Pricing starts at $0 monthly and $0.002 per text plus carrier fees.
TextKit’s strongest angle is removing the compliance, testing, and observability headaches around SMS—not merely simplifying one API call.
- –Sandbox mode lets developers test messaging flows and webhooks without contacting real users.
- –MCP support gives Claude, ChatGPT, Cursor, and other agents access to texting, contacts, numbers, and delivery tools.
- –Automated 10DLC registration and built-in STOP, START, and HELP handling address major US messaging friction.
- –Lower base pricing could appeal to startups, though carrier fees, deliverability, and US/Canada-only coverage remain constraints.
- –Two-way messaging, delivery logs, verification, broadcasts, and spend limits make it more complete than a basic SMS gateway.
