   If you subscribe to [arXiv Artificial Intelligence (cs.AI)](https://papers.cool/arxiv/cs.AI), where the URL is \`https://papers.cool/arxiv/cs.AI\`, extract the part \`https://papers.cool/\` to the end, and use it as the parameter to fill in. Therefore, the route will be [\`/papers/arxiv/cs.AI\`](https://rsshub.app/papers/arxiv/cs.AI).
