A very small announcement: you can now use the API key
d6d0f0065f4348a4bdfe4587ba02714b to always trigger an API response with
429 which means you are requesting too quickly and should slow down.
This is similar to the keys we make available for testing
responses. We hope this leads to better testing and more robust SDKs.
All of the various response codes the geocoding API can return can be found in our API documentation, and the testing keys are also listed in our guidelines for SDK or client application development.
