Who it is for
- Developers of AI agents and retrieval apps who want models to read current pages, docs and code, not only training data.
- Sales and investment research teams who look up companies, people and similar sites by description.
- Researchers who search papers and long articles by meaning.
- Claude and Cursor users who want to give an assistant web search through MCP.
Prospect research: Exa finds the companies, EveryInfra checks their social accounts
B2B sales and investment teams often start a list from one sentence, such as "D2C pet food brands in Southeast Asia". Exa's index covers web pages, people and companies, so a natural-language query is a good way to find them. To decide which ones to contact, you then need to see what they actually do on social platforms.
- Build the list. Run the sentence through Exa search with structured output, so results come back as JSON with company name, website and country, plus citations.
- Check company accounts. For each company, use the EveryInfra LinkedIn company page and jobs endpoints to get headcount, follower count and the roles it is hiring for now.
- Check brand activity. Use the Instagram profile and posts endpoints for followers, posting frequency and engagement on recent posts. For brands aimed at China, also look up the Xiaohongshu account.
- Score. Rank the list by open roles plus engagement rate, and let sales contact the 20 most active first.
If a company has no LinkedIn or Instagram account to find, EveryInfra returns an empty result and does not charge. EveryInfra also has its own 17 web search and reading tools (EverySearch); for plain web search, run the same queries through both and compare results and price.
