Financial data,
built for AI agents.
Ticker0 is a financial data provider delivering real-time stock and crypto data through MCP server, REST API, and CLI — designed for AI agents from the ground up.
Mission
AI agents need reliable financial data, not clunky legacy APIs. Whether you're building a trading bot, a portfolio analyzer, or an AI assistant that answers market questions — getting clean, structured financial data shouldn't be the hard part.
We built Ticker0 so AI agents can access stock and crypto data natively. Through MCP server, REST API, and CLI — real-time quotes, historical data, and market insights, all designed for machine consumption from day one.
Why AI-First
Traditional financial data providers bolt on AI support as an afterthought — a community MCP wrapper over a REST API designed for humans reading docs. We started with agents and worked backwards.
From progressive tool discovery to token-efficient responses, every design decision optimizes for how agents actually consume data.
Progressive Tool Discovery
Agents don't need 200 tools dumped into context. Our MCP server exposes tools progressively — fewer tokens, better results.
Structured for LLMs
Responses are designed for token efficiency. Clean JSON, consistent schemas — your agent spends tokens on decisions, not parsing.
CLI as First Class
The only financial data provider with a real CLI. Terminal-based agents like Claude Code and Codex can query data directly.
Auth That Just Works
API keys, OAuth, bearer tokens — following MCP standards so your agent framework handles auth correctly out of the box.
Start at $0
No contracts, no minimums, no "contact sales." Sign up, get a key, make your first call — in under a minute.
Cost Controls Built In
Set spending limits, per-agent budgets, and usage alerts. Your experimental agent won't burn through your quota at 3am.
