Why choose FinFeedAPI?
One API Instead for Many Products
FinFeedAPI replaces multiple data providers with a single, consistent API.
This removes the need to manage different formats, contracts, and update cycles.
Built on Proven Infrastructure
FinFeedAPI is created by the team behind CoinAPI and runs on production-grade infrastructure.
It is designed for sustained, high-volume usage in real applications.
Coverage Across Key Financial Data Types
Access historical stock data, FX and crypto exchange rates, SEC filings, and prediction markets data in one place.
This allows teams to build products without stitching together unrelated datasets.
Clean, Standardized Data Models
All datasets are delivered using consistent schemas and field naming.
This reduces time spent on parsing, mapping, and data cleanup.
Predictable Developer Experience
Endpoints, authentication, and response formats follow consistent patterns across products.
This makes integrations easier to build, test, and maintain over time.
Flexible Data Delivery Options
Choose REST, WebSocket, JSON-RPC, or S3 flat files depending on how data is consumed.
The same datasets are available through different access methods.
Bulk Data When You Need It
Large historical datasets can be accessed via flat files instead of APIs.
This supports offline analysis, research workflows, and data warehousing.
AI-Ready with MCP Support
FinFeedAPI integrates with the Model Context Protocol for use in LLM-based applications.
Structured financial data can be consumed directly by AI agents and workflows.
Reduced Operational Overhead
Data ingestion, processing, and updates are managed by FinFeedAPI.
Teams can focus on product logic instead of maintaining data pipelines.
Designed for Real Applications
FinFeedAPI is built for teams shipping production systems, not experiments or demos.
The platform prioritizes stability, clarity, and long-term maintainability.
Use cases
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.
