Developer API keys

Developer API keys let trusted tools operate your Subscription Manager account through the public API.

​

When to use an API key

Use an API key when you want a script, assistant, or automation tool to:

• List subscriptions.
• Analyze spending.
• Find duplicate subscriptions.
• Create or update subscriptions after confirmation.
• Read audit history.

Do not use API keys in public browser code or shared prompts.

​

Create a key

1. Sign in.
2. Open Settings.
3. Go to Developer API.
4. Enter a key name.
5. Create the key.
6. Copy the full key immediately.

The full key is shown only once. After that, the app only shows the key prefix.

​

Revoke a key

Open Settings > Developer API and revoke any key you no longer use. Revoking a key stops future API requests that use it.

​

Limits

Free accounts can have fewer active keys and lower hourly request limits than premium accounts. The Developer API screen shows your current plan, active key count, and hourly request limit.

​

Safety tips

• Use one key per integration.
• Revoke keys that are no longer needed.
• Rotate a key if it may have appeared in logs, screenshots, or prompts.
• Prefer read-only keys for analysis-only agents when your deployment supports scoped key creation.
