Best SMS API Providers for Cursor

Zernio is a unified social media API platform that enables developers and AI agents to publish, schedule, and manage content across 14+ social networks through a single integration. Instead of building and maintaining separate integrations with each platform's API, developers make one API call and Zernio handles authentication, media formatting, rate limits, and platform-specific requirements. The platform supports Instagram Business and Creator APIs, TikTok Business API, LinkedIn Company and Personal APIs, YouTube Data API, Twitter/X API, Facebook Graph API, Meta Business Suite, Pinterest API, Google My Business API, Reddit API, Threads API, Bluesky API, and WhatsApp Business API. Key capabilities include post scheduling and publishing, content management across all platforms, comments and DMs automation, analytics tracking, ads management, media upload and management, webhook notifications, rate limit management, and automatic token refresh. Zernio is designed for developers and technical teams building products that require social media functionality, including SaaS companies embedding social features into their own products, agencies managing client accounts at scale, and AI agent builders who need programmatic social posting. The product is white-label, meaning end users never see Zernio branding. Developer-friendly SDKs and comprehensive API documentation support fast implementation, reducing integration time from months to under an hour. A free version and free trial are available, with usage-based pricing.

Dial is an advanced communication framework for AI agents that allows software to possess its unique phone identity, enabling it to manage voice calls, SMS, and WhatsApp messaging through a single REST API, MCP server, CLI, or SDK. This innovative system reimagines a traditional telephone stack, which was initially designed for human users, incorporating elements like SIM cards, carrier agreements, handsets, and verification processes, so that autonomous agents can operate without the need for specialized hardware or manual carrier setups. With Dial, agents can acquire a legitimate phone number, execute AI-driven voice calls for tasks such as making reservations, confirming appointments, or following up, while also utilizing live transcription services with the option to transfer to a human operator if necessary. Furthermore, Dial facilitates two-way SMS and WhatsApp communication, handles inbound calls and messages, and incorporates AI receptionist functionality along with streamed incoming events. Agents are also equipped to receive SMS verification codes for workflows that require phone authentication and can programmatically respond to various communication events, enhancing their operational efficiency and capabilities. This versatility positions Dial as a crucial tool in the evolving landscape of AI communication.
