Historical data is unlimited, supporting both research and compliance use cases.
What you get
Historical stock prices
T+1 data on 11K+ symbols with unlimited historical data loopback period.
Nano-second precision timestamps
Ensuring a competitive edge and regulatory compliance in high-frequency trading by fair, accurate, and auditable transaction sequencing.
Trade data feeds
Trade records with timestamps, sizes, prices, and trade conditions (e.g., odd lot, intermarket sweep, extended hours).
Level 1 data - Quotes
Basic pricing information including best bid and best ask price, bid and ask size, and timestamp.
Level 2 data - Price Level Book
Insight into the depth of the market, including multiple bid and ask prices and aggregate order sizes at each price level.
Level 3 data - Order Book

Metadata lookup
Retrieve a complete list of all tradable symbols with statuses and security categories.
OHLCV

MCP compability
Plug the API directly into AI applications with almost no effort.
MCP compability for seamless data integration
FinFeedAPI supports the Model Context Protocol (MCP), an open specification that makes our financial data APIs machine-readable. This allows AI models, autonomous agents, and next-generation crypto apps to programmatically discover and integrate our data with little to no custom code.
Key benefits for users include:
- Easy AI Integration: Directly connect FinFeedAPI data to large language models (LLMs) and AI agents.
- Simplified Development: Access all FinFeedAPI services through a single, unified MCP endpoint, eliminating the need for custom wrappers.
- Increased Reliability: Schema-level validation catches errors and ensures more robust integrations.
- Future-Proof Design: New services and endpoints are automatically discovered by your applications without requiring client-side updates.
Why this is the best choice for developers
Complete data capture
Unlike many providers who filter or sample data, we capture every message from the exchange with nanosecond-precision timestamps, ensuring no information loss and preserving the exact sequence of market events.
Intelligent processing pipeline
Our system normalizes and indexes this raw data without sacrificing any information detail. We maintain all original values, flags, and indicators that provide crucial context for sophisticated analysis.
Flexible query architecture
REST API allows you to query this comprehensive dataset using multiple parameters: by symbol (individual securities), by date (specific historical dates), by message type (admin, quotes, trades, or order book events), and by specific event types (e.g., trading halts, auction information, short sale restrictions).
Optimized response delivery
When you make an API request, our system authenticates your API key, processes your specific query parameters and retrieves the precise data subset you need from our optimized storage. You receive a consistent, well-structured JSON response.
Multiple data depth options
Depending on your needs, you can access: level 1 data (NBBO quotes), level 2 data (price level aggregation), level 3 data (individual orders), trade executions with detailed condition flags, and administrative messages with complete market context.
Use case: Trading platforms
Trading platforms need comprehensive reference data beyond price feeds, but developers struggle with fragmented sources and complex APIs, forcing them to either integrate costly enterprise solutions or build custom infrastructure from scratch.
