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.
Build, run and scale AI, from open models to governed agents
One API key and a drop-in OpenAI SDK replacement unlock 30+ open models across text, reasoning, coding, vision, embeddings, speech-to-text, text-to-speech, image and video.
Run agents connected to company context and tools with scoped memory, tool permissions, human approvals and an auditable decision trail.
Reserve NVIDIA, AMD or Tenstorrent capacity for VMs, fine-tuning and production inference when shared serverless endpoints are not enough.
AI Factory supports VPC, on-premises and air-gapped installs, with zero data retention, an EU option, SOC 2 Type II and GDPR alignment.
