Market Data API: More Resilient Data Delivery
Reliability is a key focus this month.
For Binance Options (BINANCEOPT), CoinAPI now includes a REST polling fallback when WebSocket connections are unavailable. This ensures continuous data access even during connectivity issues.
The system also introduces:
- Graceful shutdown handling
- Healthcheck support for better monitoring
Together, these changes reduce downtime risk and improve stability for real-time trading systems.
MCP API: Built Specifically for AI Agents
A major upgrade has been released for the MCP (Model Context Protocol) API.
Instead of being auto-generated from REST endpoints, the MCP API is now designed specifically for AI agents. This improves how models interact with financial data across:
- Market Data API
- Flat Files API
- Exchange Rates API
- Indexes API
This shift makes it easier to build AI workflows that rely on structured, consistent, and context-aware data — especially useful for analytics and prediction systems like those powered by FinFeedAPI.
MCP API: Upcoming Breaking Change
There is one important change to be aware of.
The SSE MCP (Server-Sent Events) API is now deprecated and will be removed on:
April 16, 2026
To avoid disruptions, users should migrate:
- from
/sse - to
/mcp(Streamable HTTP)
Market Data API: Better Historical Coverage
Historical data access has been improved with a symbol translation fallback cache.
For metrics older than 7 days:
- Missing symbol mappings are now automatically resolved
- Data availability is improved without manual fixes
This makes long-range analysis more reliable, especially when working across changing symbol standards.
Market Data API: Expanded Derivatives Support
Support has been added for Hyperliquid HIP-3 deployer perpetuals (DEPLOYER_PERPETUAL).
This includes:
- Spot metrics integration
- Quote asset fixes for better consistency
These updates improve coverage for newer derivatives markets and make cross-exchange analysis easier.
Market Data API: Cleaner OHLCV Data
Data quality continues to improve.
OHLCV aggregation now skips trades with zero price or size, which:
- Removes invalid data points
- Improves accuracy of candles
- Reduces noise in analytics
This is especially important for high-frequency strategies and backtesting.
Flat Files API: AI-Ready Data Access
The Flat Files API now includes MCP support, enabling AI-powered data exploration directly on large datasets.
This allows:
- Easier querying of flat files
- Better integration with AI agents
- More efficient handling of large historical datasets
