Any MCP client. Any language. Any agent framework.

Access

MCP. API. CLI. Pick your path.

One data source, three interfaces — each designed for how agents actually work.

MCP Server

Connect any MCP client to live market data in seconds.

Install once, use everywhere. Your AI assistants get real-time quotes, search tickers, pull historical data, and monitor portfolios — all through the Model Context Protocol.

REST API

Structured JSON for when your agents need code-level control.

Standard REST endpoints with clean, structured responses. Built for programmatic access — agent frameworks, RAG pipelines, custom integrations. API keys, OAuth, and bearer tokens supported.

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

{
  "symbol": "AAPL",
  "price": 198.52,
  "change": 1.24,
  "volume": 52300000,
  "timestamp": "2026-04-10T16:00:00Z"
}

Standard REST with clean JSON responses

CLI

Financial data at your terminal. Built for agent runtimes.

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. JSON, table, or CSV output formats.

# Install
npm install -g @ticker0/cli

# Get a quote
ticker0 quote AAPL --format json

# Search tickers
ticker0 search "artificial intelligence" --market crypto

# Historical data
ticker0 history BTC-USD --period 30d --interval 1h

No other financial data provider ships a real CLI.

AI-First

Not just an API with an MCP wrapper

Traditional financial data providers bolt on AI support. We started with agents and worked backwards.

Progressive Tool Discovery

Agents don't need 200 tools dumped into context. Ticker0's MCP server exposes tools progressively — start with search and quote, discover more as needed. Fewer tokens, better results.

Cost Controls Built In

Set spending limits, per-agent budgets, and usage alerts. Your experimental agent won't burn through your quota at 3am. Billing is transparent — per-request, no surprises.

Structured for LLMs

Responses are designed for token efficiency. Clean JSON, consistent schemas, no HTML or nested garbage. Your agent spends tokens on decisions, not parsing.

Data

Equities. Crypto. More coming.

Agents

The details agents care about

We obsess over the things that make financial data actually work in agentic workflows.

Multiple Auth Methods

API keys for simple scripts. OAuth for MCP apps. Bearer tokens for server-to-server. Follow the standards your agent framework expects.

Rate Limiting You Control

Set your own rate limits per key, per agent, per org. Get warnings before you hit them, not errors after.

Cost Budgets

Set daily or monthly spend caps. Assign budgets per API key or per team. No bill shock from runaway agents.

Organization Support

Create orgs, invite team members, manage keys centrally. Role-based access for who can see what data and spend what budget.

Usage Dashboard

See exactly what's being called, by whom, how often. Track costs in real-time. Export usage data for your own analytics.

Instant Provisioning

Sign up, get a key, make your first call — in under a minute. No sales calls, no contracts, no "contact us for pricing."

Use Cases

What agents build with Ticker0

From personal finance bots to production trading systems.

AI Financial Assistants

Build chatbots and agents that answer questions about stocks, crypto, and markets with real-time data. "What's Tesla's price?" "How has Bitcoin performed this month?"

Portfolio Monitoring Agents

Agents that watch your holdings, alert on price movements, and generate daily portfolio summaries. Set up in Claude Desktop with MCP — no code needed.

Research & Analysis Agents

Deep research agents that pull market data, compare stocks, analyze trends, and generate reports. Pair with Exa or Tavily for news context.

Trading Bots & Signals

Programmatic access via API or CLI for backtesting strategies, generating trade signals, or feeding data into quantitative models.

Developer Tools

CLI-based agents like Claude Code, Codex, or Goose can query market data while building fintech applications — without leaving the terminal.

Personal Finance

"How are my stocks doing today?" Ask Claude with Ticker0's MCP server connected. Your AI assistant becomes a financial dashboard.
