Wait Strategies
Control when content extraction happens. This matters for pages that load content dynamically — product listings, infinite scroll, delayed popups, etc.
The three wait options execute in order: wait_browser → wait_for → wait_ms.
wait_browser
When to consider page navigation complete (requires render_js=true):
| Value | Behavior |
|---|---|
domcontentloaded | HTML parsed, fastest |
load | All resources (images, CSS, scripts) loaded |
networkidle | No network activity for 500ms, most thorough |
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&wait_browser=networkidle"wait_for
Wait for a specific element to appear before extracting content. Pass a CSS selector. Times out after 15 seconds if the element isn't found.
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&wait_for=.product-list"wait_ms
A fixed delay in milliseconds, applied after the previous wait steps resolve. Useful for content that appears after JS animations or transitions. Range: 0–30,000ms.
# Wait for the product list, then wait another 2 seconds for lazy-loaded images
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&wait_for=.product-list&wait_ms=2000"Combining Wait Options
You can chain all three. They execute in order:
wait_browser=networkidle— wait for all network activity to stopwait_for=.dynamic-content— then wait for this elementwait_ms=1000— then wait 1 more second
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&wait_browser=networkidle&wait_for=.dynamic-content&wait_ms=1000"Header Forwarding
Pass custom HTTP headers to the target site. This is useful when scraping pages that require authentication tokens, specific cookies, or custom headers.
Prefix any header with sdrive- and set forward_sdrive_headers=true. ScrapeDrive strips the prefix and forwards the header to the target.
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&forward_sdrive_headers=true" \
-H "sdrive-Authorization: Bearer my-token" \
-H "sdrive-X-Custom: my-value"The target site receives Authorization: Bearer my-token and X-Custom: my-value.
Resource Blocking
Speed up page loads by blocking unnecessary resources.
block_resources=true (default) — Blocks images, CSS, fonts, and tracking scripts. This is already on by default and significantly speeds up scraping. Gets auto-disabled when taking screenshots.
block_ads=true — Blocks advertisement scripts and content. Off by default.
# Block ads too
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&block_ads=true"
# Disable all blocking (needed if you want images/CSS in the HTML)
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://example.com&block_resources=false"Timeouts
Control the maximum time ScrapeDrive waits for a page to load.
| Mode | Default | Maximum |
|---|---|---|
| Sync | 95,000ms | 95,000ms |
| Async | 130,000ms | 130,000ms |
Minimum for both: 10,000ms.
# Give the page up to 30 seconds
curl "https://sync.scrapedrive.com/api/v1/scrape?api_key=YOUR_KEY&url=https://slow-site.com&timeout_ms=30000"If the page doesn't load within the timeout, you get a 504 response.
