Datacircle is a middleware service for B2B data APIs. According to the official description, users can use it to query their commonly used B2B data APIs, and the official emphasis is the same request, the same price, no markup, meaning it does not resell data access through markups.
In terms of integration, Datacircle supports direct use from AI tools such as Claude, ChatGPT, or Cursor by adding api.datacircle.dev/mcp as an MCP server, thereby invoking its data API capabilities within these clients.
In addition, the Datacircle official website provides a comparison feature for LinkedIn profile APIs. The page displays every LinkedIn profile API it can find side by side, with comparison dimensions including: the fields returned by each API, the cost required to scrape 1,000 profiles, and the freshness of the data (timeliness), with the goal of helping users find the best real-time available LinkedIn profile API.
Regarding other aspects of the service, such as the complete API catalog, specific billing methods, the range of supported data sources, usage restrictions, and detailed operating steps, the materials do not currently provide them, so they cannot be confirmed.
