Static metadata about the API itself: name, version, the auth scheme, the rate-limit ladder, the response envelope shape, the full error code catalog with HTTP status mapping, and the supported symbol + exchange catalogs. No I/O - pure in-memory dict, sub-millisecond. Use this when you want a single programmatic source of truth for client-side validation: the supported-symbols list, the error-code table, and the auth requirements all come from one call so your client doesn’t drift from the API contract.
