HTTP Error 429 when returned by OSM editing API is caused by too many changes in a short period of time. This Rate Limiting measure has been added to combat Vandalism. Unfortunately sometimes new mappers may run into these limits unexpectedly: in those cases it's best to take a pause from mapping for an hour and try uploading again.

If you are running bot/imports/mass edits: be aware of the Automated Edits code of conduct and Import/Guidelines.

429 is a general HTTP rate limit error and can be returned for example by the Overpass API[1]
