Zillow Group Bridge data APIs

Create an account on the Bridge Interactive Platform registration page, then request the relevant Zillow Group dataset/API in the Bridge dashboard (API Access → Request Data Access → Zillow Group Datasets → agree to terms → choose dataset/API → Apply). After approval, get your token from the Bridge dashboard under Data Access → API Access Tokens. Zillow Group's developer pages describe this as password and access-token or API-key authentication depending on the dataset.
