Authentication

ProofRails uses API keys for API access.

X-API-Key: <your_project_api_key>

API keys can be scoped to a project. Admin keys may be able to access cross-project and analytics surfaces depending on deployment configuration.

Create a project

POST /v1/projects/register

Manage keys

POST   /v1/auth/api-keys
GET    /v1/auth/api-keys
DELETE /v1/auth/api-keys/{id}

Security guidance

  • Do not ship API keys in client-side code.
  • Store server-side keys in environment variables or a secret manager.
  • Rotate exposed keys immediately.
  • Use separate keys for development, staging, and production.
