The public API uses stateless authentication only. ## Scopes API keys are granted specific scopes that determine what operations they can perform. Each endpoint documents its required scope(s). ## Rate Limiting API calls are rate limited per API key. Rate limit information is returned in response headers: - `X-RateLimit-Limit`: Maximum requests per minute - `X-RateLimit-Remaining`: Remaining requests in current window - `X-RateLimit-Reset`: When the rate limit resets (ISO 8601) ## Request ID All responses include an `X-Request-Id` header for debugging and support. You can also pass your own `X-Request-Id` header to correlate requests. contact: name: MSPortal Support email: support@msportal.ai license: name: Proprietary servers: - url: https://app.msportal.ai description: Production (US) -
