Get an API key, make your first request, and read exactly what comes back. From here you can reach every endpoint, all four products and the MCP server.
01 · Quickstart
Sign up for a key, send one request, and read what comes back. There is no SDK to install.
Sign up and we create an API key for you straight away. It starts with oga_ and is shown once, so keep it somewhere safe.
Send a request over HTTPS with your key in the header. The simplest one is a GET to /v1/area with a postcode.
Every value comes back with where it came from and when it was measured, so you always know what you are looking at.
curl https://onegoodarea.onrender.com/v1/area?postcode=SW1A%201AA \
-H "Authorization: Bearer oga_your_api_key"02 · Products
Use them on their own or together. Each one has its own page with the full detail.
