Overview

Metrics in the Blockworks API are curated, time-series datasets that track key blockchain network statistics like revenue, token supply, or DEX volume. Each metric provides historical data across multiple blockchain projects with consistent methodology and formatting.

​
Projects and Assets

In the context of metrics, a “project” refers to an asset from the assets collection. When you request metrics data, you specify projects using their asset slugs (like ethereum, bitcoin, solana).

​
Payload Structure

The response is a JSON object with the following structure: 
{
  [project_slug1]: [
    { "date": "2015-08-07", "value": 56324 },
    { "date": "2015-08-08", "value": 123456 },
    { "date": "2025-08-07", "value": 1175055.45 },
    // ...
    { "date": "2025-08-13", "value": 1175055.45 }
  ],
  [project_slug2]: [
    { "date": "2015-08-07", "value": 56324 },
    { "date": "2015-08-08", "value": 123456 },
    { "date": "2025-08-07", "value": 1175055.45 },
    // ...
    { "date": "2025-08-13", "value": 1175055.45 }
  ]
}
Each project’s data is an array of objects with two fields:
FieldTypeDescription
datestringISO-8601 date (YYYY-MM-DD)
valuenumberMetric value for that date in the specified unit

​
Single Project

To request data for a single project, use the project query parameter with the project slug.
cURL
curl -H "x-api-key: YOUR_API_KEY" \
  "https://api.blockworks.com/v1/metrics/rev-usd?project=ethereum"
When requesting data for one project, the response contains a single key-value pair: 
{
  "ethereum": [
    { "date": "2015-08-07", "value": 0 },
    { "date": "2015-08-08", "value": 0 },
    { "date": "2025-08-07", "value": 1175055.45 }
  ]
}

​
Multiple Projects

To request data for multiple projects, use the project query parameter with a comma-separated list of project slugs.
cURL
curl -H "x-api-key: YOUR_API_KEY" \
  "https://api.blockworks.com/v1/metrics/rev-usd?project=ethereum,arbitrum,optimism"
When requesting multiple projects, each project gets its own key in the response:
Response
{
  "ethereum": [
    { "date": "2015-08-07", "value": 0 },
    { "date": "2025-08-07", "value": 1175055.45 }
  ],
  "arbitrum": [
    { "date": "2021-05-28", "value": 0 },
    { "date": "2025-08-07", "value": 45230.12 }
  ],
  "optimism": [
    { "date": "2021-11-11", "value": 0 },
    { "date": "2025-08-07", "value": 23450.67 }
  ]
}

​
Historical Coverage

Each metric provides the complete historical dataset for every supported project:
  • Full history: Data starts from the project’s earliest available date
  • Consistent methodology: Same calculation method across all projects and time periods
  • Daily granularity: Most metrics provide daily data points
  • Up-to-date: Data is regularly updated with the latest values
