Symbol catalog

GEThttps://api.skylit.ai/v1/symbols

Every symbol the API serves: whether it is an index, previous tickers after a rename (still accepted as input), the metrics available, and the UTC dates its history covers (null when coverage could not be read). History dates are refreshed every few hours. Free.

Authorization

Authorization: Bearer <your API key>

Required. A missing header returns 401; an invalid, revoked or expired key returns 403.
