Auth & Profile Setup

When to Use

• First-time cdcx setup
• Configure multiple profiles (e.g. production + UAT)
• Verify credentials work
• Troubleshoot authentication errors

Resolution Order

cdcx resolves credentials in this order (first match wins):

1. --api-key / --api-secret command-line flags
2. CDCX_API_KEY / CDCX_API_SECRET environment variables (preferred prefix)
3. CDC_API_KEY / CDC_API_SECRET environment variables (legacy prefix)
4. ~/.config/cdcx/config.toml profile (default profile, or --profile <name>)

Setup Methods

Interactive Wizard (recommended)

cdcx setup

Prompts for API key, secret, and profile name. Writes ~/.config/cdcx/config.toml with mode 600. Handles migration from the legacy CDC_ variables.

Environment Variables

export CDCX_API_KEY="your-key"
export CDCX_API_SECRET="your-secret"
cdcx account summary -o json

Prefer this for CI or containers where you don't want a config file on disk.

Config File (manual)

~/.config/cdcx/config.toml:

[profiles.default]
api_key = "your-key"
api_secret = "your-secret"

[profiles.uat]
api_key = "uat-key"
api_secret = "uat-secret"
env = "uat"

Must be mode 600 — cdcx refuses to read world-readable credential files.

Profiles

cdcx --profile uat account summary         # Use UAT profile
cdcx --profile default account summary     # Explicit default

CDCX_PROFILE=uat cdcx account summary      # Env var alternative

Environment Selection

Valid --env values: production (default), uat.

cdcx --env uat market ticker BTC_USDT
cdcx --env production account summary

--env is independent of --profile. You can override either or both per call.

Verify

# Public call (no auth)
cdcx market ticker BTC_USDT -o json

# Auth check
cdcx account summary -o json

# Verbose — shows which profile / env resolved
cdcx --verbose account summary

Troubleshooting

Symptom	Cause	Fix
"No credentials found"	No flags, env vars, or config profile	Run cdcx setup or export CDCX_API_KEY/CDCX_API_SECRET
HTTP 401 / signature invalid	Wrong key/secret or clock skew	Re-run cdcx setup; ensure system clock is within a few seconds of UTC
"Permission denied" on config	File mode not 600	chmod 600 ~/.config/cdcx/config.toml or re-run cdcx setup (auto-fixes)
UAT calls hitting production	--env not set on the profile	Add env = "uat" to the profile or pass --env uat
"Withdrawal not enabled"	API key lacks withdrawal permission	Re-issue the key with withdrawal permission in the Exchange web GUI

Notes

• Credentials never appear in cdcx output or logs. Verbose mode only confirms which profile was resolved
• Do not commit ~/.config/cdcx/config.toml to version control; it is explicitly not git-tracked
• UAT has its own keypair — production keys do not work against UAT and vice versa
