# Bytemine > API-first B2B contact data and enrichment platform for sales, marketing, RevOps, GTM, and AI workflows. 135M+ contacts, 80M+ mobile numbers, 10M+ companies. Includes a no-code platform, REST APIs, a LinkedIn Agent for autonomous prospecting, and an MCP Server for AI assistants (Claude, ChatGPT, Cursor). ## Disambiguation Bytemine.ai is a B2B contact data and enrichment platform. It is not bytemine.io, the trading/signals product. Official domain: https://www.bytemine.ai. Bytemine helps revenue and AI teams find, enrich, and validate B2B prospect data through three surfaces: a no-code Platform Suite, a Developer Suite of REST APIs (B2B Contact & Company, Company Lookalikes, ICP Builder, Web Crawler, Email Verification, Signals, AI Tool Integrations, MCP Server), and an autonomous LinkedIn Agent. Pricing is usage-based and predictable: Starter is free with 500 credits/month for 12 months; Pro is $250/month. 1 credit = 1 complete contact. ## Core pages - [Homepage](https://www.bytemine.ai/): Product overview, pricing, and 500 free credits offer -
