# What is Orthogonal?

> Trusted skills and APIs for AI agents. The building blocks your agent needs.

Orthogonal provides trusted, ready-to-install skills and APIs that make AI agents more capable. Search for what you need, install it, and your agent gains new abilities instantly.

## How It Works

<Steps>
  <Step title="Find a Skill">
    Browse the [skill catalog](https://orthogonal.com/skills) or [API directory](https://orthogonal.com/discover) to find what your agent needs — lead enrichment, web scraping, email verification, and more.
  </Step>

  <Step title="Install It">
    Add a skill to your agent with one command or one line of config. Skills work with OpenClaw, Claude Code, Codex, and any agent that reads markdown.
  </Step>

  <Step title="Your Agent Gets Smarter">
    Your agent can now use those capabilities autonomously — calling APIs, chaining workflows, and delivering results without you managing keys or reading docs.
  </Step>
</Steps>

## Add to Your Agent

<Tabs>
  <Tab title="Skills">
    Install skills from the [catalog](https://orthogonal.com/skills) with one command:

    ```bash theme={null}
    # Using the Orth CLI
    orth skills add linkedin-scraper
    ```

    Each skill teaches your agent how to use a specific API — authentication, parameters, workflows, and error handling included. Works with OpenClaw, Claude Code, Codex, and any agent that reads markdown.

  <Tab title="MCP Server">
    Add to Claude Desktop, Cursor, or any MCP client:

    ```json theme={null}
    {
      "mcpServers": {
        "orthogonal": {
          "url": "https://mcp.orth.sh"
        }
      }
    }
    ```

    Your agent can search and call any API in our catalog through MCP tools.

  <Tab title="API Key">
    Use the Orthogonal API directly for programmatic access:

    ```bash theme={null}
    export ORTHOGONAL_API_KEY=orth_live_your_key
    ```

    One key gives you access to every API in the catalog. Search, get details, and run calls.

## What Can Your Agent Do?

With Orthogonal skills installed, your agent can:

```
You: Research Acme Corp and find their CEO's contact info

Agent: I'll use my lead enrichment skills to gather that.

[Uses linkedin-scraper skill to find company profile]
[Uses person-lookup skill to identify the CEO]
[Uses find-email skill to get their email]

Here's what I found:

**Company:** Acme Corp
**CEO:** Jane Smith
**Email:** jane@acmecorp.com
**LinkedIn:** linkedin.com/in/janesmith
**Recent funding:** Series B, $45M
```
