Read the API documentation →Usage scope
No API key is required. By default, expensive endpoints share a caller limit of 10 requests per minute and 100 per 24 hours, subject to site-wide lookup budgets and concurrency limits. Quota exhaustion returns 429; a busy service returns 503. Wait for the Retry-After interval before retrying. Responses are not cacheable and cross-origin browser access is disabled. Use manual checks or occasional integrations; batch queries and an availability SLA are not offered.
