429Too Many Requests
You have sent more requests than the server allows in a given period, so it is refusing until the limit resets.

Rate limiting. Nothing is wrong with the request itself; there have simply been too many of them. A well-behaved 429 includes a Retry-After header saying how long to wait, and many APIs also send headers describing the limit and how much of it remains.
What to do about it
Wait for the period named in Retry-After, then retry. Retrying immediately usually extends the block rather than getting through it.
In code, back off progressively rather than at a fixed interval, and add a small random delay so that many clients recovering at once do not all retry in the same instant and trigger the limit again.
