Overview

Ticker0 is an AI-first financial data provider. Real-time stock and crypto data delivered through MCP server, REST API, and CLI.

What is Ticker0?

Ticker0 provides real-time stock and crypto market data designed for AI agents. Unlike traditional financial data APIs, Ticker0 is built from the ground up for how agents consume data — through MCP servers, a first-class CLI, and clean REST APIs with structured, token-efficient output.

Access Methods

Ticker0 offers three ways to access financial data:

MCP Server

Connect any MCP-compatible client to live market data. Works with Claude Desktop, Cursor, VS Code, and any MCP client.

{
  "mcpServers": {
    "ticker0": {
      "command": "npx",
      "args": ["-y", "@ticker0/mcp"]
    }
  }
}

REST API

Standard REST endpoints with clean, structured JSON responses. Built for programmatic access — agent frameworks, RAG pipelines, custom integrations.

curl https://api.ticker0.com/v1/quote/AAPL \
  -H "Authorization: Bearer tk0_live_..."

CLI

A first-class CLI that speaks the same language as your terminal-based agents. Pipe output, script queries, or let Claude Code and Codex call it directly.

npm install -g @ticker0/cli

ticker0 quote AAPL --format json
ticker0 search "artificial intelligence" --market crypto
ticker0 history BTC-USD --period 30d --interval 1h
