Use a custom date range

Swap period for from and to if you need a specific window:

curl

curl "https://api.ngnmarket.com/v1/indices/ASI/chart?from=2026-01-01&to=2026-03-31&format=chart" \
  -H "Authorization: Bearer ngm_live_YOUR_KEY"

Need full OHLCV detail?

Drop format=chart and use format=detailed instead. Each point then includes date, value, change, and change_percent fields individually.
