Datafeed configuration

GEThttps://atlas-api.skylit.ai/v1/config

The static UDF DatafeedConfiguration — supported resolutions, exchanges, symbol types, and feature flags. Free.

Also carries max_fetch_trading_days: the /v1/history request-window cap, keyed by every advertised resolution. Read it once at startup and size your history pages from it, rather than hardcoding a window that later drifts — or discovering the limit by being rejected, which costs a credit each time. This call is free precisely so the limit is knowable in advance.

The values are served from the same limits the server enforces, so they cannot disagree with it. A charting client can ignore the field: it is not part of the UDF spec, and TradingView skips config keys it does not recognise.

⚠ Cached for an hour (max-age=3600), so treat a 400 naming a max_days SMALLER than your cached value as authoritative and re-read this endpoint.
