GroundAPI Is Now Live — Real-Time Data APIs Built for AI Agents
After months of development, GroundAPI is officially launching today.
Why We Built GroundAPI
When building AI Agents, we discovered a core pain point: Agents need real-time data to perform tasks (checking stock prices, looking up weather, tracking packages), but developers have to integrate with multiple data providers, each with different authentication methods, response formats, and pricing models.
The idea behind GroundAPI is simple — one Key to query all data. We've unified data formats so AI Agents can access structured, real-time information with minimal development effort.
14 Data APIs
The initial launch includes APIs across three categories, covering the most common data needs of AI Agents:
Finance
| API | Path | Purpose |
|---|---|---|
| Stock Data | /v1/finance/stock | Real-time quotes, historical K-line, technicals |
| Stock Screening | /v1/finance/stock/screen | Conditional screening, rankings, signals |
| Market Overview | /v1/finance/market | Index data, sector rotation, macro snapshot |
| Fund Data | /v1/finance/fund | Fund listings, rankings, details |
Information
| API | Path | Purpose |
|---|---|---|
| Web Search | /v1/info/search | Multi-engine real-time internet search |
| Web Scraping | /v1/info/scrape | Jina Reader smart extraction |
| Trending News | /v1/info/news | Categorized news feeds |
Life Services
| API | Path | Purpose |
|---|---|---|
| Weather | /v1/life/weather | Current weather, 7-day forecast |
| Logistics Tracking | /v1/life/logistics | Major global courier companies |
| IP Geolocation | /v1/life/ip | IP location lookup |
Three Ways to Connect
In addition to the traditional REST API, we natively support MCP (Model Context Protocol) and CLI, so your AI Agent can call our services directly from Claude Desktop, Cursor, or the terminal:
# REST API
curl "https://api.groundapi.net/v1/finance/stock?symbol=600519" \
-H "X-API-Key: sk_live_xxxxx"
# MCP — Use directly in Claude Desktop
mcp.groundapi.net/mcp + X-API-Key
# CLI
pip install groundapi-cli
groundapi config set-key sk_live_xxxxx

Every account gets 500 free API calls per month. Beyond that, pay-as-you-go pricing starts at just $0.001 per call. Sign up to get your API Key — no credit card required.
We believe real-time data is the infrastructure layer for AI Agents. GroundAPI's mission is to make accessing data as natural as breathing.
