Scrapfly Crawler API uses WARC files to provide you with complete, archival-quality snapshots of your crawled data. + + **Recommended for Large Crawls** WARC files are the **most efficient** way to retrieve and archive crawled data, especially for large crawls (100s-1000s+ pages). They provide complete HTTP transaction data in a compressed, industry-standard format that can be processed offline without additional API calls. + + + +## What is WARC? + + WARC (Web ARChive) is an ISO standard (ISO 28500:2017) for archiving web content. It captures complete HTTP request/response pairs, including headers, status codes, and response bodies. + +### Key Benefits + +- **Complete Data** - Captures full HTTP transactions (request + response) +- **Industry Standard** - Universally supported by archival and analysis tools +- **Compressed Storage** - Gzip compression for efficient storage +- **Offline Processing** - Query and analyze data without API calls +- **Long-term Archival** - Format designed for preservation +- **Tool Ecosystem** - Many libraries and tools available + +## WARC File Structure + + A WARC file contains a series of **records**. Each record has: + +- **WARC Headers** - Metadata about the record (record type, IDs, timestamps) +- **HTTP Headers** - HTTP request or response headers (if applicable) +- **Payload** - The actual content (HTML, JSON, binary data, etc.) + +### Record Types + + | Record Type | Description | Content | +|---|---|---| +| `warcinfo` | File metadata and crawl information | Crawler version, settings, timestamps | +| `request` | HTTP request sent to the server | Request method, URL, headers, body | +| `response` | HTTP response received from server | Status code, headers, response body (HTML, JSON, etc.) | +| `conversion` | Extracted/converted content | Markdown, text, or clean HTML extracted from response | + + + + + +## Scrapfly Custom WARC Headers + + In addition to standard WARC headers, Scrapfly adds custom metadata to help you analyze and process your crawled data more effectively. + +### Custom Headers for All Records + + | Header | Type | Description | +|---|---|---| +| `WARC-Scrape-Log-Id` | String | Unique identifier for the scraping log entry. Use this to: - Track individual page scrapes - Look up detailed logs in dashboard - Cross-reference with billing data | +| `WARC-Scrape-Country` | String (ISO 3166) | ISO 3166-1 alpha-2 country code of the proxy used (e.g., `US`, `GB`, `FR`). Useful for analyzing geo-specific content variations. | + + + + + +### Custom Headers for Response Records + + | Header | Type | Description | +|---|---|---| +| `WARC-Scrape-Duration` | Float (seconds) | Time taken to complete the HTTP request in seconds (e.g., `1.234`). Useful for performance analysis and identifying slow pages. | +| `WARC-Scrape-Retry` | Integer | Number of retry attempts for this request (`0` means first attempt succeeded). Helps identify problematic URLs that required retries. | + + + + + +### Example WARC Record with Custom Headers + + ``` +WARC/1.0 +WARC-Type: response +WARC-Record-ID: +WARC-Date: 2025-01-15T10:30:45Z +WARC-Target-URI: https://web-scraping.dev/products/page/1 +Content-Type: application/http;

Combine the power of recursive crawling with intelligent data extraction for fully automated web scraping pipelines. + +##### Pattern-Based Extraction + + Extraction rules allow you to apply different extraction strategies to different page types within the same crawl. For example, extract product data from `/products/*` pages and article content from `/blog/*` pages - all in a single crawler configuration. + + + +## How Extraction Rules Work + + The `extraction_rules` parameter maps URL patterns to extraction configurations. As the crawler visits each page, it checks if the URL matches any defined patterns and automatically applies the corresponding extraction method. + + + +## Configuration Syntax + + The `extraction_rules` parameter accepts a JSON object mapping URL patterns to extraction configurations: + + ``` +{ + "extraction_rules": { + "/products/*": { + "type": "model", + "value": "product" + }, + "/blog/*": { + "type": "prompt", + "value": "Extract the article title, author, publish date, and main content" + }, + "/reviews/*": { + "type": "template", + "value": "ephemeral:" + } + } +} +``` + + + + + + + + + + + +### Pattern Format + +- **Exact match**: `"/products/special-page"` matches only that specific URL path +- **Wildcard**: `"/products/*"` matches all pages under /products/ +- **Multi-level**: `"/category/*/products/*"` matches nested paths +- **Maximum length**: 1000 characters per pattern + +###### Pattern Matching Rules + +- Patterns are matched against the URL path only (not domain or query parameters) +- The **first matching pattern** is used - order matters! +- If no pattern matches, the page is crawled but not extracted + + + +## Extraction Methods + + Extraction rules support the same three extraction methods available in the [Extraction API](https://scrapfly.home/docs/extraction-api/getting-started): + + + +##### Auto Model + + `type: "model"` + + Use

In the context of the Crawler API, to ensure you received a crawler event, you must check the header `X-Scrapfly-Webhook-Resource-Type` and verify the value is `crawler`. + + To enable webhook callbacks, specify the `webhook_name` parameter in your crawler requests and optionally provide a list of `webhook_events` you want to be notified about. Scrapfly will then call your webhook endpoint as crawl events occur. + + Note that your webhook endpoint must respond with a `2xx` status code for the webhook to be considered successful.

This mechanism helps prevent tampering and ensures that webhook payloads are from trusted sources. + +#### HMAC Overview + + HMAC is a cryptographic technique that combines a secret key with a hash function (in this case, SHA-256) to produce a fixed-size hash value known as the HMAC digest. This digest is unique to both the original message and the secret key, providing a secure way to verify the integrity and authenticity of the message. + +#### Signature in HTTP Header + + When Scrapfly sends a webhook notification, it includes an HMAC signature in the `X-Scrapfly-Webhook-Signature` HTTP header. This signature is generated by applying the HMAC-SHA256 algorithm to the entire request body using your webhook's secret key (configured in the webhook settings). + +#### Verification Example + + To verify the authenticity of a webhook notification, compute the HMAC-SHA256 signature of the request body using your secret key and compare it with the signature provided in the `X-Scrapfly-Webhook-Signature` header: + + ``` +import hmac +import hashlib + +# Example secret key (replace with actual secret key from webhook settings) +secret_key = b'my_secret_key' + +# Example webhook payload (replace with actual payload) +webhook_payload = b'{"event": "crawler_finished", "crawler_uuid": "..."}' + +# Compute HMAC-SHA256 signature +computed_signature = hmac.new(secret_key, webhook_payload, hashlib.sha256).hexdigest() + +# Compare computed signature with received signature +received_signature = '...' # Extracted from X-Scrapfly-Webhook-Signature header +if computed_signature == received_signature: + print("Signature verification successful. Payload is authentic.") +else: + print("Signature verification failed. Payload may have been tampered with.") + +``` + + + + + + + +> **Security Best Practices**- Always verify the HMAC signature before processing webhook payloads +> - Keep your webhook secret key confidential and rotate it periodically +> - Use HTTPS endpoints for webhook URLs to encrypt data in transit +> - Implement rate limiting on your webhook endpoint to handle high-frequency events + +## Next Steps + +- Create your first webhook in the [webhook dashboard](https://scrapfly.home/dashboard/webhook) +- Learn about [crawler configuration options](https://scrapfly.home/docs/crawler-api/getting-started) +- Review [error handling](https://scrapfly.home/docs/crawler-api/errors) for webhook failures + +# Crawler API Billing + + The Crawler API billing is simple: **crawler cost = sum of all Web Scraping API calls made during the crawl**. + +## How It Works + + **Each page crawled = 1 Web Scraping API request** The crawler makes individual scraping requests for each page it discovers.

For API errors and error codes, see the [Errors page](https://scrapfly.home/docs/crawler-api/errors). + + **Pro Tip:** Always check the [monitoring dashboard](https://scrapfly.home/docs/monitoring) to inspect crawler status, failed URLs, and detailed error information. + +## Crawler Not Discovering URLs + + If your crawler isn't discovering the URLs you expect, this is usually a path filtering issue. Here's how to diagnose and fix it: + +### Check Path Filters + +The most common cause is overly restrictive `include_only_paths` or `exclude_paths` filters. + +##### Debugging Steps: + +1. **Test without filters first** - Run a small crawl (e.g., `max_pages=10`) without any path filters to verify URL discovery works +2. **Add filters incrementally** - Start with broad patterns and gradually make them more specific +3. **Check pattern syntax** - Ensure patterns use correct wildcards: + - `*` matches any characters within a path segment + - `**` matches across multiple path segments + - Example: `/products/**` matches all product pages +4. **Review crawled URLs** - Use `/crawl/{uuid}/urls` endpoint to see which URLs were discovered + + + + + +### Enable Sitemaps + + If your target website has a sitemap, enable `use_sitemaps=true` for better URL discovery. Sitemaps provide a comprehensive list of URLs that might not be linked from the homepage. + +### Verify Starting URL + + Ensure your starting URL is accessible and contains the links you expect. Test it manually in a browser to verify. + +## Crawler Not Following External Links + + If you expect the crawler to follow links to external domains but it's not happening, here's what to check: + +##### Common Issues: + +1. **Missing `follow_external_links=true`** - By default, the crawler stays within the starting domain. You must explicitly enable external link following. +2. **Too restrictive `allowed_external_domains`** - If you specify this parameter, ONLY domains matching the patterns will be followed. Check your fnmatch patterns (e.g., `*.example.com`). +3. **External pages not being re-crawled** - This is expected behavior! External pages are scraped (content extracted, credits consumed), but their links are NOT followed. The crawler only goes "one hop" into external domains. + + + + + +### Understanding External Link Behavior + + **Important: External Domain Crawling** When `follow_external_links=true`: + +- **With no `allowed_external_domains`:** ANY external domain is followed (except social media) +- **With `allowed_external_domains`:** Only matching domains are followed (supports fnmatch patterns) + + **Key limitation:** External pages ARE scraped but their outbound links are NOT followed. + *Example:* Crawling `example.com` ā†’ finds link to `wikipedia.org/page1` ā†’ scrapes wikipedia.org/page1 ā†’ does NOT follow links from wikipedia.org/page1 + + + +## High Failure Rate + + If many pages are failing to crawl, check the error codes to identify the root cause: + + ``` +# Get all failed URLs with error details +curl https://api.scrapfly.home/crawl/{uuid}/urls?key=scp-live-d8ac176c2f9d48b993b58675bdf71615&status=failed +``` + + + + + + + + + + + +### Common Causes and Solutions + + | Error Pattern | Solution | +|---|---| +| [`ERR::ASP::SHIELD_PROTECTION_FAILED`](https://scrapfly.home/docs/crawler-api/error/ERR::ASP::SHIELD_PROTECTION_FAILED) | Enable `asp=true` to bypass anti-bot protection This activates Anti-Scraping Protection | +| [`ERR::THROTTLE::MAX_CONCURRENT_REQUEST_EXCEEDED`](https://scrapfly.home/docs/crawler-api/error/ERR::THROTTLE::MAX_CONCURRENT_REQUEST_EXCEEDED) | Reduce `max_concurrency` to avoid overwhelming the target server Try starting with max\_concurrency=2 or 3 | +| [`ERR::SCRAPE::UPSTREAM_TIMEOUT`](https://scrapfly.home/docs/crawler-api/error/ERR::SCRAPE::UPSTREAM_TIMEOUT) | Increase `timeout` parameter or reduce `rendering_wait` Default timeout is 30 seconds, increase if needed | +| [`ERR::SCRAPE::BAD_UPSTREAM_RESPONSE`](https://scrapfly.home/docs/crawler-api/error/ERR::SCRAPE::BAD_UPSTREAM_RESPONSE) | Verify the target domain is accessible and DNS is working correctly Check if the website is online | + + For complete error definitions and solutions, see the [Crawler API Errors page](https://scrapfly.home/docs/crawler-api/errors). + +## Crawler Taking Too Long + + Crawler performance depends on several factors. Here's how to optimize speed: + +### Increase Concurrency + + The `max_concurrency` parameter controls how many pages are crawled simultaneously. Higher values = faster crawls, but stay within your account limits. + + **Recommended values:**- Small sites (< 100 pages): `max_concurrency=5` +- Medium sites (100-1000 pages): `max_concurrency=10` +- Large sites (1000+ pages): `max_concurrency=20+` (if account allows) + + + + + +### Optimize Feature Usage + + | Feature | Performance Impact | When to Disable | +|---|---|---| +| `asp` | **5Ɨ slower** | Disable if the site doesn't have anti-bot protection | +| `rendering_wait` | Adds delay per page | Reduce or remove if pages load quickly | +| `proxy_pool=public_residential_pool` | Slower than datacenter | Use datacenter proxies when residential IPs aren't required | + +### Set Time Limits + + Use `max_duration` to prevent indefinite crawls. The crawler will stop gracefully when this limit is reached: + + ``` +{ + "url": "https://example.com", + "max_duration": 3600, + "max_pages": 1000 +} +``` + + + + + + + + + + + +This crawler will stop after 1 hour or 1000 pages, whichever comes first + +## Budget Control Issues + + Controlling costs is critical when crawling large websites. Use these strategies to stay within budget: + +### Set Credit Limits + + Use `max_api_credit` to automatically stop crawling when your budget is reached: + + ``` +{ + "url": "https://example.com", + "max_api_credit": 1000, + "max_pages": 10000 +} +``` + + + + + + + + + + + +This crawler will stop after spending 1000 credits or 10000 pages, whichever comes first + +### Monitor Costs in Real-Time + + Check the crawler status endpoint to see current credit usage: + + ``` +curl https://api.scrapfly.home/crawl/{uuid}/status?key=scp-live-d8ac176c2f9d48b993b58675bdf71615 +``` + + + + + + + + + + + + The response includes `api_credit_used` showing total credits consumed so far. + +### Reduce Per-Page Costs + +- **Disable ASP** if not needed - saves significant credits per page +- **Use datacenter proxies** instead of residential when possible +- **Enable caching** for re-crawls to avoid re-scraping unchanged pages +- **Use stricter path filtering** to crawl only necessary pages +- **Choose efficient formats** - markdown and text are cheaper than full HTML + + For detailed pricing information, see [Crawler API Billing](https://scrapfly.home/docs/crawler-api/billing). + +## Debugging Tips + +### Check Crawler Status + + The status endpoint provides real-time information about your crawler: + + ``` +curl https://api.scrapfly.home/crawl/{uuid}/status?key=scp-live-d8ac176c2f9d48b993b58675bdf71615 +``` + + + + + + + + + + + +**Key fields to monitor:** + +- `status` - RUNNING, COMPLETED, FAILED, CANCELLED +- `urls_discovered` - Total URLs found by the crawler +- `urls_crawled` - Total URLs successfully crawled +- `urls_failed` - Total URLs that failed to crawl +- `api_credit_used` - Credits consumed so far + +### Inspect Failed URLs + + Get detailed error information for failed pages: + + ``` +curl https://api.scrapfly.home/crawl/{uuid}/urls?key=scp-live-d8ac176c2f9d48b993b58675bdf71615&status=failed +``` + + + + + + + + + + + +### Test with Small Crawls First + + Before running a large crawl, test with `max_pages=10` to: + +- Verify path filters are working correctly +- Check that target pages are accessible +- Confirm content extraction is working +- Estimate costs for the full crawl + +## Getting Help + + If you're still experiencing issues after trying these solutions: + +- Check the [monitoring dashboard](https://scrapfly.home/docs/monitoring) for detailed logs +- Review the [error codes reference](https://scrapfly.home/docs/crawler-api/errors) for specific errors +- Contact [support](https://scrapfly.home/docs/support) with your crawler UUID for personalized assistance + +## Related Documentation + +- [Crawler API Getting Started](https://scrapfly.home/docs/crawler-api/getting-started) +- [Crawler API Errors](https://scrapfly.home/docs/crawler-api/errors) +- [Crawler API Billing](https://scrapfly.home/docs/crawler-api/billing) +- [Monitoring Dashboard](https://scrapfly.home/docs/monitoring) + diff --git a/tests/test_crawler.py b/tests/test_crawler.py new file mode 100644 index 0000000..2ea3e3b --- /dev/null +++ b/tests/test_crawler.py @@ -0,0 +1,1306 @@ +""" +Comprehensive Crawler API Tests + +Tests the Scrapfly Crawler API functionality including: +- Basic crawling workflow +- Status monitoring +- Artifact retrieval (WARC and HAR formats) +- Content formats (HTML, markdown, text, etc.) +- Content retrieval methods (read, read_iter, read_batch) +- Path filtering and crawl options +- Error handling +""" + +import os +import pytest +import time +from scrapfly import ( + ScrapflyClient, + CrawlerConfig, + Crawl, + ScrapflyCrawlerError, +) + + +# Test configuration +API_KEY = os.environ.get('SCRAPFLY_KEY', 'scp-live-d8ac176c2f9d48b993b58675bdf71615') +API_HOST = os.environ.get('SCRAPFLY_API_HOST', 'https://api.scrapfly.home') + + +@pytest.fixture +def client(): + """Create a ScrapflyClient instance for testing""" + return ScrapflyClient( + key=API_KEY, + host=API_HOST, + verify=False + ) + + +@pytest.fixture +def test_url(): + """Base URL for testing - use web-scraping.dev""" + return 'https://web-scraping.dev/products' + + +def assert_crawl_successful(crawl): + """Helper to verify a crawl completed successfully""" + status = crawl.status() + assert status.is_complete, f"Crawl {crawl.uuid} should be complete but status is: {status.status}" + assert not status.is_failed, f"Crawl {crawl.uuid} failed with status: {status.status}" + assert status.urls_crawled > 0, f"Crawl {crawl.uuid} should have crawled at least one URL" + return status + + +class TestCrawlerBasicWorkflow: + """Test basic crawler workflow: start, monitor, retrieve results""" + + def test_basic_crawl_workflow(self, client, test_url): + """Test complete crawl workflow: start -> wait -> get results""" + config = CrawlerConfig( + url=test_url, + page_limit=5, + max_depth=2 + ) + + #
