Three ways to integrate

MCP for agents. SDK for apps. API for everything else.

Works with:

mcp.json

{
  "mcpServers": {
    "orthogonal": {
      "url": "https://mcp.orth.sh"
    }
  }
}

Everything you need to build with APIs, without the headaches.

One Orthogonal key gives you access to every API in our marketplace. Stop managing dozens of keys.

No subscriptions, no commitments. Pay only for what you use. Perfect for prototyping and agents.

"I need an API to scrape websites." Describe what you need and find the right API instantly.

API failing? Your agent can dynamically switch to another provider.

Built from the ground up for AI agents. Works with Claude, ChatGPT, Cursor, and any MCP-compatible tool.

Search, scraping, AI models, datasets, weather, social media, and more. New APIs added regularly.
