ArcDelta — API

AUTHENTICATION

Pass the API key

For REST use the X-API-Key header. For WebSocket you can pass api_key as a query param. The secret is shown once when created.

curl 'https://arcdelta.trevms.com/api/v1/gold/ohlcv?symbol=BTCUSDT&timeframe=1h' \
  -H 'X-API-Key: trms_your_key'

One TreVmS account key. Prefix trms_ (older keys tvms_ still work). ArcDelta checks only the ArcDelta quota. A spent Labs quota does not reject this call.

RATE LIMITS

ArcDelta plan limits

These numbers are only the ArcDelta allowance. Terminal and Labs are metered separately on the same key.
