> MCP server for [Orbis](https://orbisapi.com) — gives Claude, Cursor, and any AI agent access to **2,800+ APIs** with x402 USDC micropayments on Base. **$0.01/call. No signup.**
---
## What this does
This MCP server connects your AI agent to the Orbis API marketplace. Your agent can:
- **Browse** 2,800+ APIs across data, AI, finance, and utilities
- **Call** any API directly — payment handled automatically via x402 on Base
- **No API keys** — agents pay per call in USDC, no accounts needed
---
## Quickstart
### Claude Desktop
Add to `claude_desktop_config.json`:
```json
{
"mcpServers": {
"orbis": {
"command": "npx",
"args": ["-y", "@orbisapi/mcp"]
}
}
}
```
**Config file location:**
- macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
- Windows: `%APPDATA%\Claude\claude_desktop_config.json`

## How payments work
Orbis uses the [x402 protocol](https://x402.org) — an open HTTP payment standard built on Base. When your agent calls an API:
1. Orbis returns a `402 Payment Required` response with payment details
2. The MCP server handles the USDC payment on Base automatically
3. The API call completes — total cost: **$0.01**
No wallets to configure for browsing. To make paid calls, provide your Base wallet via `ORBIS_KEY`.
