What are the benefits of Multi-source company API?

The key feature that distinguishes the data you’re getting with this API from other alternatives in the market is the level of detail in each company profile. Company records include more than 300 data points. Here’s a broad overview of the available data collections in each record:

  • Main company information (firmographics)
  • Growth insights based on historical data
  • Online presence and reviews
  • Financials and funding
  • Technographics and products

Our multi-source company data is also unique because of the steps we take to make this data as comprehensive, fresh, and valuable for businesses as possible:

  1. Filtering. The dataset is filtered to remove empty or low-value records.
  2. Cleaning. Standardizing date formats and removing HTML tags, among other actions, makes the dataset more readable, consistent, and ready to work with.
  3. Enrichment. We add additional fields using proprietary methods, including a specially instructed large language model (LLM) that allows us to extract more accurate company descriptions, categories, and keywords.
  4. Mapping. We map the data from different sources and unify everything into a single output.

How does it work?

Multi-source company API is designed to find and get company data on demand and enrich the information you already have. Thanks to Elasticsearch, you can run full-text search queries. One search/collection/enrichment request consumes two credits.

Search requests. Finding relevant company records is seamless. You can formulate queries using a long list of filters as search parameters.

Collection requests. To get the relevant records, use profile URL slugs or unique company IDs retrieved during the search in our database.

Enrichment requests. Enriching the information you already have with extensive and fresh data. Use company domains, profile URL slugs, or unique profile IDs to collect the records that you need.

Key advantages

  1. Save data engineering resources. We take care of time-intensive data collection and processing steps on behalf of you, which saves valuable data engineering resources. Handling all the nuances of data cleaning means your data engineers can focus on strategic tasks rather than routine data processing.
  2. Shorter time to value. Mapping the data from multiple sources, removing low-value records and simplifying the data structure with only relevant and cleaned fields means that you have more time to work on extracting value from data instead of solving the challenges that raw data sometimes presents.
  3. Enhanced data quality. Our extensive process for this dataset, including cleaning, aggregation, and the added value from enrichment, eliminates redundancies and ensures that the data is comprehensive and of high quality.
  4. Insights from historical data. For this dataset, we also aggregate historical data, marking percentage changes over time in certain company metrics that signal growth trends, such as headcount, social followers, active job posting count, and reviews changes month-over-month.
