note: >-
  Common Paper's REST API and hosted MCP server both use Bearer-token
  authentication. A single API token is supplied in the Authorization header; the
  organization is inferred from the token (no organization-id header). Tokens are
  generated from the account Integrations tab or minted programmatically via the
  agentic provisioning flow. The end-user web application (app.commonpaper.com)
  is fronted by Auth0. The API is served through a Zuplo gateway (token prefix
  zpka_).

    Two unauthenticated public gateway endpoints support agentic signup: mint a
    single-use provision key, then redeem it for a new organization + admin user
    and receive a production API key.
  endpoints:
  - POST /v1/keys      # mint a one-time provision key (contact_email required)
  - POST /v1/accounts  # redeem provision key -> new org + production api_key
  rate_limits: 5 req/minute, 50 req/day per IP (provision key minting)
