如何将 RSS 订阅源连接到 AI 智能体

// digest.mjs
// Requires: SERENE_API_KEY, SERENE_API_URL, and OPENROUTER_API_KEY env vars.
// Your API settings page in SereneReader has the base URL and endpoint paths.

const SERENE_API_KEY = process.env.SERENE_API_KEY;
const SERENE_API_URL = process.env.SERENE_API_URL; // from your API settings page
const OPENROUTER_API_KEY = process.env.OPENROUTER_API_KEY;

import { writeFileSync } from "node:fs";

// 1. Fetch yesterday's articles from SereneReader
const yesterday = new Date(Date.now() - 86400000).toISOString();
const res = await fetch(`${SERENE_API_URL}?since=${yesterday}`, {
  headers: { Authorization: `Bearer ${SERENE_API_KEY}` },
});

if (!res.ok) {
  console.error(`SereneReader API error: ${res.status}`);
  process.exit(1);
}

const { articles } = await res.json();

if (articles.length === 0) {
  console.log("No new articles since yesterday.");
  process.exit(0);
}

// 2. Build a prompt from article titles and snippets
const articleList = articles
  .map((a) => `- ${a.title} (${a.feedName})\n  ${a.snippet}`)
  .join("\n\n");

const prompt = [
  `Here are ${articles.length} articles from my RSS feeds`,
  `published in the last 24 hours:\n\n${articleList}\n\n`,
  `Write a concise daily digest. Group related articles`,
  `by topic. For each topic, summarize the key points in`,
  `2-3 sentences. Include the article titles so I know`,
  `which ones to read in full.`,
].join(" ");

// 3. Send to any model via OpenRouter
const llmRes = await fetch("https://openrouter.ai/api/v1/chat/completions", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${OPENROUTER_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    model: process.env.OPENROUTER_MODEL, // set to the model ID you want from openrouter.ai/models
    messages: [{ role: "user", content: prompt }],
  }),
});

if (!llmRes.ok) {
  console.error(`OpenRouter API error: ${llmRes.status}`);
  process.exit(1);
}

const { choices } = await llmRes.json();
const summary = choices[0].message.content;

// 4. Write the digest to a local markdown file
const date = new Date().toISOString().split("T")[0];
const output = `# Daily Digest - ${date}\n\n${summary}\n`;
writeFileSync(`digest-${date}.md`, output);

console.log(`Digest written to digest-${date}.md (${articles.length} articles)`);
