API Keys

API keys authenticate requests to the 2027.dev MCP server and API.

Creating a key

  1. Sign in to 2027.dev/evals
  2. Go to SettingsAPI Keys
  3. Click Create Key and give it a name
  4. Copy the key immediately — it won’t be shown again
API keys start with evals_ and are tied to your organization.

Security

  • Keys are hashed before storage — we cannot recover a lost key
  • Each key is scoped to your organization’s data
  • Keys can be revoked at any time from the Settings page

Authorization: Bearer evals_YOUR_API_KEY
