Description

21st is a development platform designed to help engineers quickly build and deploy AI agents inside their applications. The platform provides a specialized SDK that simplifies the process of defining agent behavior, integrating tools, and connecting AI models. Developers can create agents using familiar technologies such as Next.js, React, TypeScript, Python, and Node.js, making integration straightforward for modern applications. Once an agent is defined, the platform allows it to be deployed with a single command while automatically handling infrastructure requirements. 21st provides sandboxed execution environments through E2B sessions, ensuring that agent operations run securely and independently. The platform includes a ready-to-use chat interface component that can be embedded directly into an app for user interaction. Additional features include token streaming, conversation history, tool execution, and built-in observability for debugging and monitoring. Developers can replay sessions and trace tool calls to better understand how agents behave during execution. The system also supports spend limits, authentication controls, and rate limiting to manage AI usage across users. By combining development tools with managed infrastructure, 21st helps teams launch scalable AI agents without building complex backend systems.

Description

Paygent serves as a cutting-edge profitability and monetization infrastructure specifically designed for businesses that rely on AI technologies. Unlike traditional billing systems that merely account for revenue, Paygent focuses on the critical metrics that AI companies prioritize, such as the margin generated by each agent, the real gross profit associated with each customer, and the instantaneous costs tied to every LLM call, API request, and computational event. Among its notable features are: - Immediate cost attribution for LLM usage based on agent, customer, and workflow - Simulation tools for predictive pricing that allow businesses to strategize pricing models prior to launching into production - Automation of billing processes for various pricing models, including usage-based, outcome-based, hybrid, and digital employee frameworks - Automated invoicing coupled with cost alert notifications to identify and mitigate runaway agent loops that could harm profitability With seamless integration through Node.js, Python, and Go SDKs, Paygent adds no latency to agent operations. Eliminate uncertainty regarding your margins and transform your AI agents into a thriving business venture. By leveraging Paygent, companies can gain a clearer understanding of their financial landscape and make informed decisions that drive profitability.
