Listings API authenticates server-to-server integrations with API keys.

API keys

Production keys (<your-api-key>) carry the access level: Read or Write: that you choose when you create them.

Create and rotate keys in the dashboard → API Keys area.

A sandbox day pass key uses the same header and starts with dp.. You can sign up for a day pass, or an AI agent can get one for its user without the dashboard: it requests the day pass, and the key arrives once the user presses Start my day pass in the email or shares the emailed 6-digit code. The key covers the locations and listings endpoints and stops working when the 24 hours end. See the day pass guide.
