Try Stevens Keys: live sandbox demo

Test mode sandbox. This page talks to the real API, but only to a dedicated demo product. Demo keys are throwaway, expire after 24 hours, allow 50 calls, and can't touch any creator's data.

1. 1. Issue a demo key
2. 2. Validate it (calls POST /v1/validate, the same endpoint your MCP server would)
3. 3. Revoke it
4. 4. Validate again: the very next call is denied
5. Try a made-up key

Key: none yet
