SDK Release (March 19th, 2025)

We’re excited to announce the release of the Messari SDK, a powerful TypeScript library that provides seamless access to all Messari APIs. Getting started is as simple as providing your API key:

const client = new MessariClient({ apiKey: "YOUR_API_KEY" });

To get an API key, signup at Messari and navigate to our api page.

Core Metrics API Expansion

Our updated Core Metrics API endpoints have been significantly expanded with new endpoints for Assets, Markets and Exchanges. The new Metrics v2 Assets endpoints will replace the existing Market Data and Asset services, these enhanced endpoints include:

Asset Details: Access comprehensive information about specific assets including classification, descriptions, and market data all in one convenient endpoint
All-Time High (ATH) Information: Access detailed ATH data including dates, prices, and percentage changes from peak values
Return on Investment (ROI) Metrics: Comprehensive ROI data across multiple timeframes (24h, 7d, 30d, 1y, 3y, 5y) for performance analysis
Asset Coverage Details: Easily determine what Messari datasets are available for each asset, whether it’s Diligence, News, or Research
Asset Metrics Catalog: Browse the complete catalog of available metrics and datasets for assets, helping you discover what data points are available
Asset Time-Series Data: Access comprehensive historical metrics for any asset with flexible time range selection, perfect for detailed trend analysis
Granularity-Specific Time-Series: Retrieve asset metrics at predefined time intervals (hourly, daily, weekly), allowing for precise data resolution that matches your analytical needs

Deprecation Notice

The legacy Market Data and Assets family of endpoints are now deprecated. All functionality from these endpoints has been consolidated into the new Core Metrics Assets v2 endpoints for improved consistency and performance. We recommend migrating to the new endpoints at your earliest convenience.

Example Usage

// Get asset details with ATH information
const athInfo = await client.asset.getAssetDetails({
  slugs: "bitcoin,ethereum",
});

// Get V2 assets with coverage information
const assetsWithCoverage = await client.asset.getAssetsV2({
  has_market_data: true,
  limit: 10,
});
