@anycrawl/js-sdk

A lightweight ESM JavaScript/TypeScript client for the AnyCrawl API.

Requirements

• Node.js 18+ (Node 20 recommended – matches CI)
• ESM modules

Install

pnpm add @anycrawl/js-sdk

Quickstart

import { AnyCrawlClient } from "@anycrawl/js-sdk";

// Prefer loading from env in your app framework
const client = new AnyCrawlClient(process.env.ANYCRAWL_API_KEY || "<YOUR_API_KEY>");
// Base URL defaults to https://api.anycrawl.dev, but you can override:
// const client = new AnyCrawlClient(process.env.ANYCRAWL_API_KEY!, "https://api.anycrawl.dev");

// Health
await client.healthCheck(); // -> { status: "ok" }

// Scrape (engine defaults to "auto" — automatically picks the best engine)
const scrape = await client.scrape({
    url: "https://example.com",
    formats: ["markdown"],
});

// Crawl (async job)
const job = await client.createCrawl({
    url: "https://anycrawl.dev",
    max_depth: 3,
    strategy: "same-domain",
    limit: 50,
    scrape_options: { formats: ["markdown"] },
});
const status = await client.getCrawlStatus(job.job_id);
const page1 = await client.getCrawlResults(job.job_id, 0);

// Cancel if needed
// await client.cancelCrawl(job.job_id);

// Blocking helper (waits until the crawl finishes and aggregates all pages)
const aggregated = await client.crawl(
    {
        url: "https://anycrawl.dev",
        max_depth: 3,
        strategy: "same-domain",
        limit: 50,
    },
    2, // poll interval (seconds)
    10 * 60_000 // optional timeout (ms)
);
// aggregated.data contains all results

// Map (discover all URLs from a website)
const mapResult = await client.map({
    url: "https://anycrawl.dev",
    limit: 100,
    include_subdomains: false,
    ignore_sitemap: false,
});
// mapResult.links contains all discovered URLs

// Search (optionally enrich with scraping)
const results = await client.search({
    query: "OpenAI ChatGPT",
    engine: "google",
    pages: 1,
    limit: 10,
    scrape_options: { engine: "cheerio", formats: ["markdown"] },
});

Usage details

Client

new AnyCrawlClient(apiKey: string, baseUrl = "https://api.anycrawl.dev", onAuthFailure?: () => void)

• apiKey: Bearer token for API calls.
• baseUrl: Override if self-hosting.
• onAuthFailure: Invoked on 401/403. Useful to trigger sign-out or refresh.

You can also set LOG_LEVEL to control internal logs (debug, info, warn, error).

scrape(input)

import type { Engine, ScrapeFormat } from "@anycrawl/js-sdk";

const engine: Engine = "auto"; // or "cheerio", "playwright", "puppeteer"
const formats: ScrapeFormat[] = ["markdown", "html"];

await client.scrape({
    url: "https://example.com",
    engine, // optional — defaults to "auto"
    // Optional:
    template_id: "my-template",
    variables: { key: "value" },
    proxy: "http://user:pass@host:port",
    formats,
    timeout: 60_000,
    retry: true,
    wait_for: 3000,
    wait_for_selector: ".content",
    only_main_content: true,
    include_tags: ["article", "main"],
    exclude_tags: ["nav", "footer"],
    json_options: { user_prompt: "Extract title", schema: { type: "object" } },
    extract_source: "markdown", // or "html"
    ocr_options: false,
    max_age: 86_400_000,
    store_in_cache: true,
});

Returns either a success object with content or a failure with error.

createCrawl(input), getCrawlStatus(jobId), getCrawlResults(jobId, skip?), cancelCrawl(jobId)

const job = await client.createCrawl({
    url: "https://site.com/docs",
    engine: "playwright", // optional — defaults to "auto"
    template_id: "my-template",
    variables: { section: "api" },
    max_depth: 5,
    strategy: "same-domain",
    limit: 100,
    include_paths: ["/docs/*"],
    exclude_paths: ["/admin/*"],
    scrape_paths: ["/docs/*"], // Only scrape content from these paths
    scrape_options: { formats: ["markdown"] },
});

const status = await client.getCrawlStatus(job.job_id);
const page = await client.getCrawlResults(job.job_id, 0);
// await client.cancelCrawl(job.job_id);

crawl(input, pollIntervalSeconds = 2, timeoutMs?)

Convenience wrapper that creates a crawl, polls status until it completes, and returns aggregated results of all pages. Throws on failed jobs or timeout; returns partial aggregated data when cancelled.

// Type signature
async function crawl(
    input: CrawlRequest,
    pollIntervalSeconds?: number, // default 2s
    timeoutMs?: number // optional
): Promise<CrawlAndWaitResult>;

// Example
try {
    const aggregated = await client.crawl(
        {
            url: "https://anycrawl.dev",
            max_depth: 3,
            strategy: "same-domain",
            limit: 50,
            scrape_options: { formats: ["markdown"] },
        },
        3, // poll every 3s
        5 * 60_000 // timeout after 5 minutes
    );
    console.log(aggregated.total, aggregated.completed);
    console.log(aggregated.data.length, "pages aggregated");
} catch (err) {
    // Handles API/network/auth errors, job failed, or timeout
    console.error(err);
}

• Returns: CrawlAndWaitResult with job_id, status, total, completed, creditsUsed, and aggregated data.
• Polling states: waits until completed; throws on failed; returns partial data when cancelled.
• Use getCrawlStatus/getCrawlResults if you prefer manual pagination/progress.

search(input)

await client.search({
    query: "best js tutorials",
    engine: "google",
    limit: 20,
    offset: 0,
    pages: 2,
    lang: "en",
    country: "US",
    timeRange: "week",
    sources: "web",
    template_id: "search-template",
    variables: {},
    scrape_options: { engine: "cheerio", formats: ["markdown"] },
    safe_search: 1,
});

map(input)

await client.map({
    url: "https://example.com",
    limit: 100,
    include_subdomains: false,
    ignore_sitemap: false,
});

Discovers all URLs from a website using multiple sources:

• Sitemap parsing (sitemap.xml, robots.txt)
• Search engine results (site: operator)
• Page link extraction (HTML tags)

Returns MapResult with links array containing { url, title?, description? } objects.

Scheduled Tasks

// Create
const created = await client.createScheduledTask({
    name: "Daily scrape",
    cron_expression: "0 9 * * *",
    timezone: "Asia/Shanghai",
    task_type: "scrape",
    task_payload: { url: "https://example.com", engine: "cheerio", formats: ["markdown"] },
    concurrency_mode: "skip",
    max_executions_per_day: 1,
});
// created.task_id, created.next_execution_at

// List, get, update, delete
const tasks = await client.listScheduledTasks();
const task = await client.getScheduledTask(created.task_id);
await client.updateScheduledTask(created.task_id, { cron_expression: "0 10 * * *" });
await client.pauseScheduledTask(created.task_id, "Maintenance");
await client.resumeScheduledTask(created.task_id);
await client.deleteScheduledTask(created.task_id);

// Executions
const { data } = await client.getScheduledTaskExecutions(created.task_id, { limit: 10, offset: 0 });
await client.cancelScheduledTaskExecution(created.task_id, executionId);

Webhooks

// Create
const webhook = await client.createWebhook({
    name: "My webhook",
    webhook_url: "https://your-server.com/webhook",
    event_types: ["scrape.completed", "crawl.completed"],
    scope: "all",
});
// webhook.webhook_id, webhook.secret (save secret - shown only once)

// List, get, update, delete
const webhooks = await client.listWebhooks();
const w = await client.getWebhook(webhook.webhook_id);
await client.updateWebhook(webhook.webhook_id, { event_types: ["scrape.completed"] });
await client.deleteWebhook(webhook.webhook_id);

// Deliveries, test, activate/deactivate
const { data } = await client.getWebhookDeliveries(webhook.webhook_id, { limit: 20, status: "failed" });
await client.testWebhook(webhook.webhook_id);
await client.activateWebhook(webhook.webhook_id);
await client.deactivateWebhook(webhook.webhook_id);
await client.replayWebhookDelivery(webhook.webhook_id, deliveryId);

// Supported event types
const events = await client.getWebhookEvents();
// events.event_types, events.categories

Notes:

• Engine defaults to auto when omitted — the server automatically picks the best engine (cheerio for static pages, playwright for JS-heavy pages).
• Scrape options live at top-level; crawl accepts nested scrape_options only; top-level only allows crawl strategy fields and optional retry.
• search supports optional scrape_options; when provided without engine, it is omitted (no per-result scrape enrichment; API defaults to auto when enrichment is used).

Running E2E tests

Live integration tests hit the real AnyCrawl API and consume credits. They are not included in the default pnpm test or pnpm test:coverage runs.

Prerequisites

• A valid ANYCRAWL_API_KEY
• Set ANYCRAWL_RUN_LIVE=1 to opt in (dual gate prevents accidental execution in CI)
• (Optional) ANYCRAWL_BASE_URL to test against a self-hosted instance (defaults to https://api.anycrawl.dev)

Run

# Inline env vars
ANYCRAWL_API_KEY=sk-xxx ANYCRAWL_RUN_LIVE=1 pnpm --filter @anycrawl/js-sdk test:e2e

# Or configure in root .env and run:
pnpm --filter @anycrawl/js-sdk test:e2e

The test suite is organized in tiers by credit cost:

| Tier | Tests | Credit cost | |------|-------|-------------| | 1 | healthCheck, scrape (cheerio), map | Zero / low | | 2 | Multi-engine scrape, search, createCrawl + status | Moderate | | 3 | Blocking crawl, cancelCrawl, full pagination flow | Higher | | Error | Invalid API key | Zero |

Error handling

All methods throw standard Error with readable messages. Examples:

• Authentication errors: Authentication failed: <message> (401/403) – triggers onAuthFailure if provided
• Payment required: Payment required: <message>. current_credits=<n> (402)
• API errors: API Error <status>: <message>
• Network issues: Network error: Unable to reach AnyCrawl API
• Other request errors: Request error: <message>

Wrap calls in try/catch to handle errors in your app.

Notes:

• Some endpoints return HTTP 2xx with { success: false, error?: string }. The SDK converts these into Request error: <message> (e.g., Request error: Scraping failed).
• 401 and 403 are both treated as authentication failures and will invoke onAuthFailure when set.
• For 402, when the response includes current_credits, the message is specialized as shown above; otherwise it falls back to API Error 402: <message>.
