API Access
Appealbase provides programmatic access to our planning appeal database for developers and planning tech companies who want to integrate appeal data into their own systems.

API access & authentication
REST API access is authenticated with API keys linked to your Appealbase account. Monthly call limits follow your account tier (Developer Trial, Developer Pro, or Custom).
For internal tools, prototypes, and pilots, start with Developer pricing. After you have a developer-tier account, create an API key from Account settings. Full endpoint docs are on the REST API reference.
