How this service works
Bytemine is a B2B data platform for sales and go to market teams. It covers contact and company search across 135M professionals and 10M companies, contact and company enrichment, LinkedIn profile search and enrichment, live company intelligence read from a company's own web presence, technographics, buying intent scoring, and hiring, funding, job posting, and job change signals. Search results bill per record returned, enrichment bills only on a successful match, and count queries are free. This server is a pay-per-use, transparent proxy in front of Bytemine's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. This document is the source of truth for agents: it lists the complete verified paid surface with each operation's live price in its x-payment-info. Endpoints not listed here are not part of the supported catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.
Output
Returns a paginated list of companies whose LinkedIn posts match the search keywords. Each company entry includes the company name, website URL, LinkedIn profile URL, employee count, and an array of recent LinkedIn post objects. Also returns a total_companies count for pagination purposes. Billed per company returned.
Example use cases
Identify prospects discussing competitor products
“Find companies that are posting on LinkedIn about Salesforce CRM — I want to see which businesses are actively talking about it so I can reach out with our alternative solution.”
Monitor industry buzz for market research
“Search LinkedIn posts for companies mentioning 'supply chain AI' and return the first 20 results — I need to understand who's publicly engaged with this topic for our market research report.”
Prioritize outreach by topic engagement
“Pull LinkedIn posts from companies talking about 'zero trust security' on LinkedIn — show me their employee counts and websites so I can prioritize the right-sized companies for our outbound campaign.”
Technical details
Endpoint
POSThttps://agents.bytemine.ai/functions/v1/api-gateway/linkedin-postsWhen to prefer
Use this endpoint when you need to identify companies that are actively discussing specific topics on LinkedIn, especially for sales prospecting, competitive intelligence, or market research. It is preferable over generic company search when the signal you care about is real-time social engagement and topic affinity rather than static firmographic filters. Choose this over LinkedIn profile enrichment when you don't know the companies yet and want discovery driven by content keywords.
