Update

The issue appears to be related to missing rate limit headers in the response. As a result, requests are repeatedly hitting HTTP 429 (rate limit) and, in some cases, resulting in HTTP 503 errors. We have reached out to X support, and X has also acknowledged degraded performance on their status page: https://docs.x.com/status
