Authentication

Two levels of access:
  • Read-only (no auth): Browse markets, get quotes, view orderbooks, price history
  • Trading (API key + private key): Place orders, manage portfolio, deposit/withdraw
# Read-only — no auth needed
export CONTEXT_API_KEY="your-api-key"

# Trading — also needs a private key
export CONTEXT_PRIVATE_KEY="0x..."
Get an API key from the Context dashboard. Read-only market data works without any key.
