How Data Tags Work

Data Tags make it easy to retrieve the same metric for thousands of companies using a single API request.

Why Data Tags Exist

Public companies often describe the same concept differently in their SEC filings.

For example, one company may report:

• Revenue
• Net Sales
• Total Revenue

Although the labels differ, they all represent the same financial concept. Intrinio standardizes these values under a single Data Tag so your application can retrieve comparable data without needing to interpret each company's filing.

How Data Tags Are Used

Many Fundamentals API endpoints require a Data Tag as part of the request.

For example:

• revenue
• netincome
• marketcap
• ebitda
• assets

Instead of requesting a line item by its original SEC filing label, you request it using the standardized Data Tag.

For example:

Revenue ↓  revenue 

Net Income ↓  netincome 

This standardization allows your code to work consistently across all supported companies.

Standardized vs. As-Reported Data

Data Tags are primarily used with Intrinio's standardized financial data.

Standardized financials map company-specific reporting into a common structure, making companies directly comparable.

If you need the original values exactly as they appeared in an SEC filing, Intrinio also provides access to as-reported financial data, where the original company taxonomy and labels are preserved.

Finding Available Data Tags

There are several ways to discover available Data Tags.

1. Browse the API Documentation

The API documentation lists supported Data Tags for endpoints that retrieve financial metrics.

2. Search the Data Tags API

Intrinio provides dedicated endpoints for searching and retrieving Data Tags, including:

• Search Data Tags
• Get All Data Tags
• Get Data Tag by ID

These endpoints allow you to search by keyword, browse available tags, and view metadata associated with each tag.

3. Use the Intrinio MCP Server

The easiest way to discover the correct Data Tag is through the Intrinio MCP Server.

The MCP Server understands your account permissions and can recommend the appropriate Data Tags, datasets, and API endpoints based on what you're trying to build. Rather than searching documentation manually, you can describe the metric you need in natural language and receive the appropriate Data Tag and implementation guidance.

Example

Suppose you want Apple's annual revenue.

Instead of searching Apple's SEC filing for the exact wording of its revenue line item, you simply request the revenue Data Tag for the desired reporting period.

The API returns the standardized revenue value regardless of how Apple labeled the line item in its filing.

The same request structure can then be reused for any other company.

Best Practices

• Use standardized Data Tags whenever you want to compare companies.
• Use as-reported financials only when you need the exact values and labels from SEC filings.
• Use the MCP Server to quickly identify the correct Data Tags and API endpoints for your application.
• Use the Data Tags API endpoints when building applications that need to dynamically discover available metrics.
