## 目标
每个监控都有一个或多个**目标**。目标类型决定了每次检查会执行什么： | 目标 | 监控内容 | 设置方式 | | -------- | ----------- | -------------------------------------------- | | `scrape` | 你指定的已知 URL | [页面监控](/zh/features/monitoring-page) | | `crawl` | 通过爬取发现的每个页面 | [网站监控](/zh/features/monitoring-website) | | `search` | 整个网页中的新结果 | [全网页规模监控](/zh/features/monitoring-web-scale) | 每个监控支持 1–50 个目标，并且你可以在同一个监控中混合使用不同的目标类型。`retentionDays` 的默认值为 `30`，最高可设置为 `365`。 每次创建调用都会返回新创建的监控，其中包含规范化后的 cron、计算得出的 `nextRunAt` 和 `estimatedCreditsPerMonth`。启用判定后，`estimatedCreditsPerMonth` 是一个上限估算值，因为判定额度只会对实际发生变化且被判定的页面计费： ```json Response theme={null} { "success": true, "data": { "id": "019df960-06e7-7383-9d89-82c0113dc31a", "name": "Hacker News AI monitor", "status": "active", "schedule": { "cron": "*/30 * * * *", "timezone": "UTC" }, "nextRunAt": "2026-05-17T16:00:00.000Z", "lastRunAt": null, "currentCheckId": null, "goal": "Alert when a new Hacker News story related to AI enters the top 10. Ignore changes to stories that are not about AI. Do not alert on changes outside the top 10.", "judgeEnabled": true, "targets": [ { "id": "019df960-09bb-7c11-8001-1f12f50ab1c2", "type": "scrape", "urls": ["https://news.ycombinator.com"] } ], "webhook": null, "notification": { "email": { "enabled": true, "recipients": ["alerts@example.com"], "includeDiffs": true } }, "retentionDays": 30, "estimatedCreditsPerMonth": 2880, "lastCheckSummary": null, "createdAt": "2026-05-17T15:30:00.000Z", "updatedAt": "2026-05-17T15:30:00.000Z" } } ```
## 目标与判定
如果你只想在发生有意义的变化时收到告警，请添加一个通俗易懂的 `goal`。如果设置了 `goal` 但省略了 `judgeEnabled`，Firecrawl 会自动启用判定。判定会在已发生变化的页面上运行，并返回一个 `judgment`，其中包含 `meaningful`、`confidence`、`reason` 和 `meaningfulChanges`。 目标如何应用取决于目标：[page](/zh/features/monitoring-page) 和 [website](/zh/features/monitoring-website) 监控会对已发生变化的页面进行判定，而 [entire web-scale monitors](/zh/features/monitoring-web-scale#judging) 会对每个新的搜索结果进行判定。 如果你想先保存目标、暂时不对变化进行判定，请使用 `judgeEnabled: false`。只有当监控同时设置了 `judgeEnabled` 且 `goal` 非空时，判定器才会运行。 对于 `search` 目标 (全网页规模监控) ，除非你设置了 `judgeEnabled: false`，否则 `goal` 为必填。对于 `scrape` 和 `crawl` 目标，则为可选。 每次检查都会对底层抓取或爬取照常计费。如果启用了判定，判定器还会为其验证的每个已发生变化的页面额外收取 1 个额度。没有已发生变化页面的检查不会消耗判定额度。 好的目标应简短且明确：说明什么情况应触发告警，重申任何范围限制，例如前 N 项、价格、角色类型、公司、地区、主题、状态或实体，并且仅在排除条件本身属于目标意图时才写入。如果目标范围较宽泛，就保持宽泛；例如，"任何变化" 不应再加入会掩盖变化的噪声过滤条件。 例如，一个具有以下目标的监控： ```text theme={null} 当与 AI 相关的新 Hacker News 故事进入前 10 时发出告警。忽略与 AI 无关的故事的变动。不对前 10 以外的变动发出告警。 ``` 当匹配的故事进入监控范围时，可能会生成如下这样的 `monitor.page` Webhook： ```json monitor.page theme={null} { "success": true, "type": "monitor.page", "id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "webhookId": "f1e2d3c4-0000-0000-0000-000000000000", "data": [ { "monitorId": "019df960-06e7-7383-9d89-82c0113dc31a", "checkId": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "url": "https://news.ycombinator.com", "status": "changed", "previousScrapeId": "019df94f-82c3-7e41-81f0-00c72b2d9c52", "currentScrapeId": "019df960-73ee-7ac2-97a9-fb0e442c21f1", "error": null, "isMeaningful": true, "judgment": { "meaningful": true, "confidence": "high", "reason": "A new AI-related story entered the Hacker News top 10.", "meaningfulChanges": [ { "type": "added", "after": "4. Show HN: Open-source AI coding assistant", "reason": "This is a new AI-related story inside the top 10." } ] }, "diff": { "text": "--- previous\n+++ current\n@@ -1,5 +1,6 @@\n # Hacker News\n 1. Database internals for beginners\n 2. A new approach to CSS\n 3. Building reliable queues\n+4. Show HN: Open-source AI coding assistant\n" } } ], "metadata": { "environment": "production" } } ```
## 调度计划
调度计划可以使用 cron 表达式或简单的自然语言文本来设置。 ```json Cron theme={null} { "schedule": { "cron": "*/30 * * * *", "timezone": "UTC" } } ``` ```json Text theme={null} { "schedule": { "text": "every 30 minutes", "timezone": "UTC" } } ``` 支持的自然语言示例： * `every 30 minutes` * `every 15 minutes starting at :07` * `hourly` * `every 2 hours` * `daily` * `daily at 9:00` * `daily at 9am` * `daily at 5:30 PM` * `weekly` 最短间隔为 5 分钟。API 响应始终返回规范化后的 cron 表达式。对于文本调度计划，`timezone` 用于控制像 `daily at 9am` 这类短语何时运行。文本调度计划在转换为 cron 之前，会先按监控 ID 错开分布，因此多个监控不会在同一时刻同时运行。
## 变更追踪
[页面](/zh/features/monitoring-page) 和 [网站](/zh/features/monitoring-website) 监控默认会比较每个页面的 markdown 差异，并报告 `same`、`changed`、`new`、`removed` 或 `error`。如果你想检测**特定结构化字段** (如价格、标题、库存状态标记、列表中的条目等) 的变化，请在目标的 `scrapeOptions` 中添加 `changeTracking` 格式，并设置 `modes: ["json"]`，以启用 JSON 模式的变更追踪。 变更追踪适用于 `scrape` 和 `crawl` 目标。面向整个网页规模的 (`search`) 监控会针对新结果触发告警，而不是比较已知页面的差异。请参见 [Statuses and dedup](/zh/features/monitoring-web-scale#statuses-and-dedup)。
### Markdown 模式 (默认)
当 `scrapeOptions.formats` 仅为 `["markdown"]` 时，检查 响应中的每个已变更页面都会附带统一文本 diff，以及一个 [parseDiff](https://github.com/sergeyt/parse-diff) 风格的 AST： ```json Markdown-mode diff theme={null} { "diff": { "text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n # Pricing\n-Starter — $19/mo\n+Starter — $24/mo\n", "json": { "files": [ { "from": "previous", "to": "current", "chunks": [ { "content": "@@ -1,3 +1,3 @@", "changes": [] } ] } ] } } } ```
### JSON 模式
传入 `changeTracking` 格式并设置 `modes: ["json"]`，同时提供一个 JSON schema (或用于描述你关注字段的 `prompt`) 。Firecrawl 会在每次检查时提取该 JSON，并输出一个**按字段区分的差异**，以字段路径作为键；此外还会附带一个包含当前完整提取结果的 `snapshot.json`，这样消费方就无需重新获取底层 抓取 结果。 ```python Python theme={null} from firecrawl import Firecrawl from pydantic import BaseModel from typing import List firecrawl = Firecrawl(api_key="fc-YOUR-API-KEY") class Plan(BaseModel): name: str price: str features: List[str] class Pricing(BaseModel): plans: List[Plan] monitor = firecrawl.create_monitor( name="Pricing monitor", schedule={"text": "hourly", "timezone": "UTC"}, goal="Notify me when a pricing tier, price, or headline feature changes", targets=[ { "type": "scrape", "urls": ["https://example.com/pricing"], "scrapeOptions": { "formats": [ { "type": "changeTracking", "modes": ["json"], "prompt": "Extract pricing tiers and headline features for each plan.", "schema": Pricing.model_json_schema(), } ] }, } ], notification={ "email": { "enabled": True, "recipients": ["alerts@example.com"], "includeDiffs": True, } }, ) print(monitor.id) ``` ```js Node theme={null} import Firecrawl from "@mendable/firecrawl-js"; import { z } from "zod"; const firecrawl = new Firecrawl({ apiKey: "fc-YOUR-API-KEY" }); const pricingSchema = z.object({ plans: z.array( z.object({ name: z.string(), price: z.string(), features: z.array(z.string()), }), ), }); const monitor = await firecrawl.createMonitor({ name: "Pricing monitor", schedule: { text: "hourly", timezone: "UTC" }, goal: "Notify me when a pricing tier, price, or headline feature changes", notification: { email: { enabled: true, recipients: ["alerts@example.com"], includeDiffs: true, }, }, targets: [ { type: "scrape", urls: ["https://example.com/pricing"], scrapeOptions: { formats: [ { type: "changeTracking", modes: ["json"], prompt: "Extract pricing tiers and headline features for each plan.", schema: pricingSchema, }, ], }, }, ], }); console.log(monitor.id); ``` ```bash cURL theme={null} curl -s -X POST "https://api.firecrawl.dev/v2/monitor" \ -H "Authorization: Bearer $FIRECRAWL_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "name": "Pricing monitor", "schedule": { "text": "hourly", "timezone": "UTC" }, "goal": "Notify me when a pricing tier, price, or headline feature changes", "notification": { "email": { "enabled": true, "recipients": ["alerts@example.com"], "includeDiffs": true } }, "targets": [ { "type": "scrape", "urls": ["https://example.com/pricing"], "scrapeOptions": { "formats": [ { "type": "changeTracking", "modes": ["json"], "prompt": "Extract pricing tiers and headline features for each plan.", "schema": { "type": "object", "properties": { "plans": { "type": "array", "items": { "type": "object", "properties": { "name": { "type": "string" }, "price": { "type": "string" }, "features": { "type": "array", "items": { "type": "string" } } } } } } } } ] } } ] }' ``` diff 载荷使用提取结果中的 JSON 路径作为键。每个值都是一个 `{previous, current}` 对： ```json JSON-mode diff theme={null} { "diff": { "json": { "plans[0].price": { "previous": "$19/mo", "current": "$24/mo" }, "plans[1].features[2]": { "previous": "10 GB storage", "current": "25 GB storage" } } }, "snapshot": { "json": { "plans": [ { "name": "Starter", "price": "$24/mo", "features": ["Up to 3 users", "Basic analytics", "Email support"] }, { "name": "Pro", "price": "$49/mo", "features": ["Unlimited users", "Advanced analytics", "25 GB storage"] } ] } } } ``` 即使被跟踪的字段都没有变化，但周围的 markdown 发生了变化，JSON 模式监控仍会报告 `same`，除非你同时启用 git-diff (请参见下方的混合模式) 。该 diff 只关注 schema 中定义的字段。
### 混合模式 (JSON + git-diff)
如果你同时需要结构化的逐字段差异 **以及** 原始 markdown 统一 diff，请同时传入这两种模式： ```json Mixed target (JSON + git-diff) theme={null} { "type": "scrape", "urls": ["https://example.com/pricing"], "scrapeOptions": { "formats": [ { "type": "changeTracking", "modes": ["json", "git-diff"], "prompt": "Extract pricing tiers and headline features for each plan.", "schema": { "type": "object", "properties": { "plans": { "type": "array", "items": { "type": "object", "properties": { "name": { "type": "string" }, "price": { "type": "string" } } } } } } } ] } } ``` 随后，检查 响应会同时包含 `diff.text` (markdown sidecar) 和 `diff.json` (逐字段差异) ，以及提取得到的 `snapshot.json`： ```json Mixed-mode diff (JSON + git-diff) theme={null} { "diff": { "text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n # Pricing\n-Starter — $19/mo\n+Starter — $24/mo\n", "json": { "plans[0].price": { "previous": "$19/mo", "current": "$24/mo" } } }, "snapshot": { "json": { "plans": [ { "name": "Starter", "price": "$24/mo" }, { "name": "Pro", "price": "$49/mo" } ] } } } ``` 混合模式页面会在**任一**结果形式发生变化时报告 `changed`。
## 通知
### Webhooks
当监控配置了 `webhook` 时，Firecrawl 可以发送两种监控事件： * `monitor.page`：每个被监控的 抓取 在 抓取 worker 中完成后发送。 * `monitor.check.completed`：在完整检查完成汇总后发送。包含检查状态和汇总计数。页面级结果请使用 `monitor.page` 事件或监控检查 API。 如果对已变更页面执行了有意义变更判定，`monitor.page` 会包含 `isMeaningful` 和 `judgment`。 ```json Webhook config theme={null} { "webhook": { "url": "https://example.com/webhooks/firecrawl", "headers": { "Authorization": "Bearer your-secret" }, "metadata": { "environment": "production" }, "events": ["monitor.page", "monitor.check.completed"] } } ``` `monitor.page` 载荷： ```json monitor.page theme={null} { "success": true, "type": "monitor.page", "id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "webhookId": "f1e2d3c4-0000-0000-0000-000000000000", "data": [ { "monitorId": "019df960-06e7-7383-9d89-82c0113dc31a", "checkId": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "url": "https://example.com/blog", "status": "changed", "previousScrapeId": "019df94f-82c3-7e41-81f0-00c72b2d9c52", "currentScrapeId": "019df960-73ee-7ac2-97a9-fb0e442c21f1", "error": null, "isMeaningful": true, "judgment": { "meaningful": true, "confidence": "high", "reason": "The page headline changed to announce a new release cadence.", "meaningfulChanges": [ { "type": "changed", "before": "Welcome to our weekly update.", "after": "Welcome to our weekly update — now with daily releases!", "reason": "The headline changed in a way that matches the monitor goal." } ] }, "diff": { "text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n # Latest posts\n-Welcome to our weekly update.\n+Welcome to our weekly update — now with daily releases!\n" } } ], "metadata": { "environment": "production" } } ``` `monitor.check.completed` 载荷： ```json monitor.check.completed theme={null} { "success": true, "type": "monitor.check.completed", "id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "webhookId": "f1e2d3c4-0001-0000-0000-000000000000", "data": [ { "monitorId": "019df960-06e7-7383-9d89-82c0113dc31a", "checkId": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "status": "completed", "summary": { "totalPages": 2, "same": 1, "changed": 1, "new": 0, "removed": 0, "error": 0 } } ], "metadata": { "environment": "production" } } ``` 当检查在没有页面级错误的情况下完成时，`success` 为 `true`。对于失败或部分完成的检查，它为 `false`；如果可用，`error` 会包含失败原因。
### 电子邮件
仅当某次检查出现页面变更、新增、移除或报错时，才会发送电子邮件摘要。 ```json Email config theme={null} { "notification": { "email": { "enabled": true, "recipients": ["alerts@example.com"], "includeDiffs": true } } } ``` 当某个监控设置了目标并启用判定后，电子邮件摘要会优先展示有意义的变更页面。如果所有变更页面都被判定为噪声，且没有新增、移除或报错的页面，则会抑制发送该电子邮件。 如果省略 `recipients`，Firecrawl 会将邮件发送给有资格接收系统告警邮件的团队成员。 你最多可以配置 25 个明确指定的收件人。
#### 收件人确认流程
当有新的收件人被添加到某项监控时，Firecrawl 会向其发送一封包含确认链接的电子邮件，以确保对方明确同意接收该监控的通知。如果收件人已是团队成员，则无需确认。
## 查看检查结果
使用 `GET /v2/monitor/{monitorId}/checks` 获取检查列表，使用 `GET /v2/monitor/{monitorId}/checks/{checkId}` 查看某次检查的详情。SDKs 默认会自动处理分页。 ```python Python theme={null} from firecrawl import Firecrawl firecrawl = Firecrawl(api_key="fc-YOUR-API-KEY") check = firecrawl.get_monitor_check(monitor_id, check_id, limit=25, status="changed") for page in check.pages: print(page.url, page.status) if page.judgment: print(page.judgment.meaningful, page.judgment.reason) if page.diff and page.diff.text: print(page.diff.text) if page.snapshot and page.snapshot.json: print(page.snapshot.json) ``` ```js Node theme={null} import Firecrawl from "@mendable/firecrawl-js"; const firecrawl = new Firecrawl({ apiKey: "fc-YOUR-API-KEY" }); const check = await firecrawl.getMonitorCheck(monitorId, checkId, { limit: 25, status: "changed", }); for (const page of check.pages) { console.log(page.url, page.status); if (page.judgment) { console.log(page.judgment.meaningful, page.judgment.reason); } if (page.diff?.text) { console.log(page.diff.text); } if (page.snapshot?.json) { console.log(page.snapshot.json); } } ``` ```bash cURL theme={null} curl "https://api.firecrawl.dev/v2/monitor/$MONITOR_ID/checks/$CHECK_ID?limit=25&status=changed" \ -H "Authorization: Bearer $FIRECRAWL_API_KEY" ``` 检查列表可按检查 `status` 过滤：`queued`、`running`、`completed`、`failed`、`partial` 或 `skipped_overlap`。 检查详情响应包含 `estimatedCredits`、`actualCredits`、汇总计数以及分页的 `pages` 数组。`estimatedCredits` 是该检查预留额度的上限；`actualCredits` 是 Firecrawl 在确认有多少页面发生变化并需要判定后，最终收取的额度。使用顶层 `next` URL 获取下一页结果，其分页方式与 爬取 保持一致。你还可以按页面 `status` 过滤：`same`、`new`、`changed`、`removed` 或 `error`。每个已变更页面都包含内联 `diff` 数据；来自 JSON 模式监控的页面还会包含带有当前提取结果的 `snapshot`。 ```json Markdown-mode response theme={null} { "success": true, "next": "https://api.firecrawl.dev/v2/monitor/019df960-06e7-7383-9d89-82c0113dc31a/checks/019df960-5f2a-75fb-a98b-bd2d32ca67d4?skip=25&limit=25", "data": { "id": "019df960-5f2a-75fb-a98b-bd2d32ca67d4", "monitorId": "019df960-06e7-7383-9d89-82c0113dc31a", "status": "completed", "estimatedCredits": 2, "actualCredits": 2, "summary": { "totalPages": 1, "same": 0, "changed": 1, "new": 0, "removed": 0, "error": 0 }, "pages": [ { "id": "019df960-7708-7c62-a5dc-6206f16ac122", "targetId": "019df960-09bb-7c11-8001-1f12f50ab1c2", "url": "https://example.com/blog", "status": "changed", "previousScrapeId": "019df94f-82c3-7e41-81f0-00c72b2d9c52", "currentScrapeId": "019df960-73ee-7ac2-97a9-fb0e442c21f1", "statusCode": 200, "error": null, "metadata": { "title": "Example Blog", "creditsUsed": 1 }, "judgment": { "meaningful": true, "confidence": "high", "reason": "The page headline changed to announce a new release cadence.", "meaningfulChanges": [ { "type": "changed", "before": "Welcome to our weekly update.", "after": "Welcome to our weekly update — now with daily releases!", "reason": "The headline changed in a way that matches the monitor goal." } ] }, "createdAt": "2026-05-17T15:35:00.000Z", "diff": { "text": "--- previous\n+++ current\n@@ -1,3 +1,3 @@\n #
