All REST calls go to https://api.delta.exchange/v2/. The v2 API supports futures, perpetuals, and options.

Every private request requires three headers: api-key, timestamp, and signature. The signature is an HMAC-SHA256 hash of the concatenated method, timestamp, path, and body string.

Key Endpoints

• GET /products: Lists all tradable instruments.
• POST /orders: Places a new order.
• GET /positions: Returns open positions for the authenticated user.

Rate Limits

Delta Exchange enforces per-IP and per-key rate limits. For delta exchange algo trading, stay under 30 requests per second on private endpoints to avoid 429 errors.
