Entities API

Table of contents


The Acuris Entities API allows you to search over 1M records of private and public companies, firms, assets, and private investors. 

It is delivered over HTTPS, conforms to RESTful principles, and returns JSON objects. 

Quick start 

To get the list of all the entities you are entitled to, simply query as follows: 


The ‘hits’ property in the payload shows the total number of records returned. The default response shows the first 10 items and you can paginate through the response to get additional content. The API can also be interrogated using a set of filters to fetch specific subsets of data. 


We recommend the use of GZIP compression to gain up to 80% reduction in the JSON data transfer. 


Concurrency and rate limits 

Each API key is limited to a maximum of 5 concurrent requests and 10 requests per second. Requests over the limit will receive the response ‘429 Too Many Requests’.
