What is APIbase?

Production MCP server that gives AI agents access to 789 real-world API tools through a single endpoint. Agents connect once to https://apibase.pro/mcp and can search flights, get stock quotes, check weather and tides, forecast ocean waves and swell, query US Census and CDC health data, search ML models on HuggingFace, look up World Bank indicators, query UN SDG development goals data, track streamflow from USGS stations, search 7M+ CS papers on DBLP, generate images, send emails, decode VINs, look up chemical compounds, scan npm/PyPI vulnerabilities, search NIST NVD CVE records, find EV chargers, estimate solar PV output, search art at the Met Museum, look up Dota 2 match stats, get decoded aviation METAR/TAF, look up parsed NOTAMs and PIREPs, search FDA medical device recalls and 510(k) clearances, batch multiple calls, track usage analytics — and 814 tools across 30+ categories.

Built for AI agents, not humans. Auto-registration, zero setup, pay-per-call via x402 USDC micropayments on Base or MPP (Machine Payments Protocol) on Tempo.

Quick Start (30 seconds)

Claude Desktop / Cursor / Windsurf

{
  "mcpServers": {
    "apibase": {
      "url": "https://apibase.pro/mcp"
    }
  }
}

Multi-server setup (recommended)

Combine APIbase (real-world APIs) with Playwright (browser) and Context7 (docs):

{
  "mcpServers": {
    "apibase": { "url": "https://apibase.pro/mcp" },
    "playwright": { "command": "npx", "args": ["-y", "@playwright/mcp"] },
    "context7": { "command": "npx", "args": ["-y", "@upstash/context7-mcp"] }
  }
}

With Base MCP (pay from your Base Account)

Base MCP launched May 2026 with native x402 support. APIbase is x402-native on Base mainnet — the two pair cleanly. Base MCP signs payments from your Base Account; APIbase serves 600+ external API tools.

{
  "mcpServers": {
    "base-mcp": { "url": "https://mcp.base.org" },
    "apibase":  { "url": "https://apibase.pro/mcp" }
  }
}

Zero API-key management (Base Account handles auth + signing), zero per-provider signup (APIbase aggregates 238 providers). Full guide: apibase.pro/frameworks#base-mcp.

Via npm (stdio bridge)

{
  "mcpServers": {
    "apibase": {
      "command": "npx",
      "args": ["-y", "apibase-mcp-client"]
    }
  }
}
