Is it true that as of October 2026, arXiv's published API terms ask users of its legacy APIs to make no more than one request every three seconds and to use a single connection at a time?

Yes. arXiv's own Terms of Use page for its APIs states that users of the legacy APIs (including OAI-PMH, RSS, and the arXiv API) should make no more than one request every three seconds and limit requests to a single connection at a time.
