An honest list. If one of these is what you need, it may be the better pick.
Company identification is free and unlimited on every plan. Person-level ID is US-only and charged once per person per month; repeat visits are free.
Send identified visitors to Slack, signed webhooks, or a daily or weekly email digest. From the Starter plan, filter by title, company size, and the pages they viewed, and sync contacts one way to HubSpot.
A data MCP server with 13 tools and a REST API with an OpenAPI spec. Per-key daily caps, a 250-credit default ceiling per call, read-only keys, and idempotent retries keep an agent's spending predictable.
Visitor ID, Shopper ID, the Data API, and the MCP server draw from the same credits, and every credit cost is listed on the pricing page. Misses aren't charged.
Opted-out and suppressed people are never returned, delivered, or charged. Global Privacy Control signals are honored, and the rules we enforce are published as a machine-readable policy.
Monthly plans stop at the end of the billing period, and you can set a hard monthly spend cap so overage never surprises you.

WhoLayer
| Plan | Monthly | Credits | Overage |
|---|---|---|---|
| Free | Free | 100 | None |
| Starter | $49 | 1,000 | $0.060 a credit |
| Growth | $199 | 5,000 | $0.050 a credit |
| Scale | $799 | 20,000 | $0.045 a credit |
Example: identifying 1,000 US people a month uses 1,000 credits. The cheapest fit is Starter at $49 a month. Repeat visits by the same person in a month are free, and company-level ID doesn't use credits.
