Overview

What each tool does and who it's built for.

OpenTools

OpenTools offers a specialized API designed to augment Large Language Models (LLMs) with external tool capabilities. By utilizing this single API, developers can access an open ecosystem of MCP (Machine Communication Protocol) tools, granting LLMs functionalities such as web search, real-time location data retrieval, and web scraping without needing individual API keys for each service.

The platform emphasizes seamless integration and flexibility, supporting various LLMs and ensuring applications remain resilient against outages. Its API is engineered to be OpenAI-compatible and supports traditional function calling methods. OpenTools simplifies the financial aspect by charging only for tool execution with tokens priced at-cost, consolidating all charges into one unified billing portal, thus eliminating the need to manage multiple LLM and external service accounts separately.

LLM API

LLM API enables users to access a vast selection of over 200 advanced AI models—including models from OpenAI, Anthropic, Google, Meta, xAI, and more—via a single, unified API endpoint. This service is designed for developers and enterprises seeking streamlined integration of multiple AI capabilities without the complexity of handling separate APIs for each provider.

With compatibility for any OpenAI SDK and consistent response formats, LLM API boosts productivity by simplifying the development process. The infrastructure is scalable from prototypes to production environments, with usage-based billing for cost efficiency and 24/7 support for operational reliability. This makes LLM API a versatile solution for organizations aiming to leverage state-of-the-art language, vision, and speech models at scale.
