Making a call

1. Ensure gateway is configured for voice

Run these once — they're no-ops if already set:

openclaw config set gateway.mode local
openclaw config set gateway.http.endpoints.chatCompletions.enabled true

If auth isn't set up yet:

openclaw config set gateway.auth.mode token
openclaw config set gateway.auth.token "$(openssl rand -hex 24)"

Then restart: openclaw gateway restart

2. Create the voice agent (if it doesn't exist)

openclaw agents add voice --model gemini-3.1-flash-lite-preview --non-interactive

If that errors because it already exists, skip this step.

3. Read the gateway token

openclaw config get gateway.auth.token

4. Start the bridge

OPENCLAW_GATEWAY_TOKEN=<token> stringclaw-bridge serve > /tmp/stringclaw-bridge.log 2>&1 &
sleep 8
cat /tmp/stringclaw-bridge.log

Confirm the log shows "Bridge ready" before proceeding. If it shows an error, check troubleshooting below.

5. Make the call

stringclaw-bridge call

If successful, tell the user: "Calling you now — pick up in a moment!"

Output

Success: {"success":true,"callId":"..."}

Errors (JSON on stderr):

"Invalid API key" — bad or missing STRINGCLAW_API_KEY
"No minutes remaining..." — top up at stringclaw.com
"No phone number configured..." — set at stringclaw.com/dashboard/settings
"Bridge is not running..." — start the bridge first (step 4)

Troubleshooting

Bridge log shows "Gateway 401": Wrong token. Re-read with openclaw config get gateway.auth.token.

Bridge log shows "Gateway 405": Chat completions not enabled. Run:

openclaw config set gateway.http.endpoints.chatCompletions.enabled true
openclaw gateway restart

Call connects but AI never responds: Test the gateway directly:

curl -X POST http://127.0.0.1:18789/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <token>" \
  -d '{"model":"voice","messages":[{"role":"user","content":"hi"}],"stream":true}'
