X is one of the platforms that enforce rate limits aggressively. The content shown to logged-out visitors is limited, and heavy requests from the same IP quickly receive a 429 Too Many Requests response. That is why, when working with X, request budget management matters as much as the proxy itself.
First, Choose the Right Path
The official API should always be preferred as long as the quota allows: it is stable, structured and compliant with the rules.
Rate Limit Math
If the number of requests one IP can send per hour is limited, roughly N times the volume requires N times the IPs. A simple calculation:
Pools planned without a safety margin choke on the first wave of errors. Plan for 50 IPs instead of 40.
Choosing the IP Type
X is more tolerant of datacenter ranges than other platforms; for reading public pages, datacenter proxy is usually enough and cuts costs considerably. For work that requires a session (managing your own account, scheduled posting), however, ISP proxy is needed to establish a fixed identity.
Separating the two workloads reduces both cost and risk.
Retry Strategy
429 response, the right thing to do is not to retry immediately with the same IP. A solid flow:
Retry-After — if this header is present, follow it; ignoring it extends the block duration.
X's terms of use govern automated access. This article describes the technical infrastructure; complying with the platform's current terms and applicable legislation on what data may be collected is the user's responsibility.
