# WhoLayer > WhoLayer identifies website visitors and enriches them with verified emails and mobiles, then sends them to Slack, HubSpot, Klaviyo, signed webhooks, or an AI agent. One tag powers Visitor ID (people and companies visiting a B2B site; person-level for US traffic only, company-level free and unlimited) and Shopper ID (anonymous US shoppers sent to Klaviyo). The Data API and MCP server give code and AI agents the same identity and contact data with per-key spend caps, and Identity Cloud licenses identity data to platforms. Every product draws from one credit wallet. Opted-out people are never returned or charged. Every public page has a markdown version: add `.md` to the URL (the home page is `/index.md`), or send `Accept: text/markdown`. For AI agents: a public docs MCP server at https://mcp.wholayer.com/docs (no API key), an authenticated data MCP server at https://mcp.wholayer.com/mcp, and an OpenAPI 3.1 spec for the REST API at https://wholayer.com/openapi.json. Prices and credit costs are on [Pricing](https://wholayer.com/pricing.md). Everything here is generated from the live site. ## Products - [Products](https://wholayer.com/products.md): Visitor ID, Shopper ID, Data API and MCP, and Identity Cloud: four products on one identity graph and one credit wallet. - [Visitor ID: See the people behind your pipeline traffic.](https://wholayer.com/products/visitor-id.md): Install one tag and get the name, title, LinkedIn, and verified work email of US visitors, plus the company for everyone else.
