Rotate OpenRouter Key

Safely replace the OpenRouter API key across an entire OpenClaw installation, handling all config locations, priority chains, and verification.

When to Use

• User says "rotate my openrouter key" or "change openrouter key"
• User reports 401 errors from OpenRouter
• User disabled an old key and needs to set a new one
• Periodic key rotation for security

Key Priority Chain

OpenClaw reads the OpenRouter API key from three sources, highest priority first:

1. ~/.openclaw/.env — environment file, overrides everything
2. ~/.openclaw/agents/<name>/agent/models.json — per-agent config
3. ~/.openclaw/openclaw.json — global config

If a higher-priority source has the old key, updating a lower-priority file has no effect. You must update the key at whichever level it is actually being read from.

Workflow

Step 1: Get the New Key

Ask the user for the new key. It must start with sk-or-v1-.

If the user doesn't have one yet, direct them to openrouter.ai/keys to generate one.

Step 2: Find All Key Locations

# Find every file containing an OpenRouter key
grep -r "sk-or-v1" ~/.openclaw/ --include="*.json" --include=".env" -l 2>/dev/null

# Also check for uncommented key in .env
grep -v '^#' ~/.openclaw/.env 2>/dev/null | grep OPENROUTER_API_KEY

Report what you found to the user before making changes.

Step 3: Update All Locations and Verify

Run the helper script — it handles both .env and JSON files in one pass:

python3 scripts/update-openrouter-key.py --key "sk-or-v1-NEW-KEY" --verify

The script:

• Finds all config files (.env + JSON) containing an openrouter key
• Creates timestamped backups before each write
• Updates only the key value (minimal change)
• Verifies the new key against the OpenRouter API
• Reports what it changed

Preview first with --dry-run:

python3 scripts/update-openrouter-key.py --key "sk-or-v1-NEW-KEY" --dry-run

Step 4: Restart Gateway

openclaw gateway restart

Step 5: Remote Hosts (if applicable)

If the user manages OpenClaw on other machines, repeat Steps 2-5 via SSH:

ssh <host> "grep -r 'sk-or-v1' ~/.openclaw/ --include='*.json' --include='.env' -l"

Then run the update script remotely or copy it over.

Step 6: Disable Old Key

Only after verifying the new key works everywhere, tell the user they can now safely disable/delete the old key at openrouter.ai/keys.

Scope & Boundaries

Handles: Finding, updating, and verifying OpenRouter API keys in all OpenClaw config locations.

Does NOT handle: Other provider keys (Anthropic, OpenAI). Key generation (user does that on openrouter.ai). Billing or usage issues.

Error Handling

Limitations

• Cannot generate or revoke keys (user must do that on openrouter.ai)
• Cannot update keys on remote hosts without SSH access
• Does not handle keys stored outside ~/.openclaw/ (e.g., in systemd environment files)
