The URL pattern `/api/opportunities/sport` suggests it serves structured data about cross-bookmaker arbitrage situations for a given sport.\n\nHowever, the underlying Railway deployment is currently not provisioned. Every path on the host — including the root, docs, API routes, and the endpoint itself — returns Railway's default \"train has not arrived at the station\" page, indicating the application is not running or the domain has not been properly configured. Neither a 402 x402 challenge nor any other meaningful HTTP response was captured during probing.\n\nBecause the service is entirely unreachable, no schema, pricing, documentation, or example responses are available.
