• Exceeding rate limits or usage quotas Many APIs
  and services impose restrictions on the number of
  requests a client can make in a given time
  period. If these limits are surpassed, the server
  responds with a 429 error.
• Sending excessive requests Rapidly sending
  numerous requests to a server, especially within
  a short duration, can trigger the 429 error as a
  protective measure against abuse or overloading.
• Server-side configurations Some servers are
  configured to generate a 429 error when certain
  conditions, such as high traffic or system load,
  are met.
• API rate limiting APIs often implement rate
  limiting to ensure fair usage and prevent
  resource exhaustion. If clients exceed the
  allocated request limits, the API responds with a
  429 error.
