# Stevens Keys

> License keys, edge validation and usage metering for paid MCP servers and APIs. Sell from your own site instead of a storefront. Preview, TEST MODE: no real charges, revenue is simulated, payouts via Stripe Connect are planned and not live (planned split 85/15 creator/platform). Accounts are verified manually during early access. Operated by Canada Site Ops, Ontario, Canada.

One call, `POST /v1/validate` with `Authorization: Bearer <license key>`, checks and meters a key: 200 allow, 403 deny, 401 missing. Revoked keys deny on the next validation (or within the optional `cache_ttl`, 30s default).
