+    <p>A status code of <code>429</code> indicates “Too Many Requests.” This can occur due to two reasons:</p>

-    <p>Regardless of the reason, BCDA will include a <strong>Retry-After</strong> header in its response. It's considered best practice to wait until the period specified in this header has elapsed before making further requests. This ensures your client can adapt without manual intervention, even if the rate-limiting parameters change.</p>
