A marketplace of ready-to-use APIs and MCP servers for apps and AI agents
Listed APIs speak the Model Context Protocol, so they can be attached as tools to AI agents and used by MCP-capable clients like Cursor, Claude Desktop and Continue.
Test endpoints live against models such as Claude and GPT to see how an API behaves in an actual agent-driven conversation before you commit to an integration.
Register a base URL and credentials, define inputs and outputs with a guided wizard, and deploy an MCP server that serves both humans and agents.
API Hub handles hosting, subscriptions, billing and revenue sharing, so API owners can focus on the product instead of payment plumbing.
OpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.
Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
