Tools

Capture a screenshot of a website URL, raw HTML, or Markdown content. Provide exactly one of: url, html, or markdown. Returns the image as a PNG, JPEG, WebP, or PDF. Supports device emulation (iPhone, Pixel, iPad), dark mode, ad blocking, cookie banner removal, full-page capture, and custom viewports.

Check if a screenshot is already cached without capturing a new one. Does not count against your quota. Pass the same parameters you would use for take_screenshot so the cache key matches correctly.

Generate a signed URL for a screenshot that can be used without an API key. Useful for embedding screenshots in emails, documents, or sharing with third parties. Signing is free, rendering the URL consumes one credit. URLs expire after the specified duration.

Extract content from a web page. Returns structured data based on the extraction type. Supports: markdown (readable content), text (plain text), html (raw HTML), article (structured with title/author/excerpt), links (all page links), metadata (OG tags, title, description).

Create a batch screenshot job for multiple URLs (1-50). Returns immediately with a job ID. Use get_batch_status to poll for results (wait 2-5 seconds between polls). All URLs share the same screenshot options. Each URL consumes one credit; failed URLs get credits rolled back.

Get the status of a batch screenshot job. Poll this until status is 'completed' or 'failed' (wait 2-5 seconds between polls). Completed items include presigned download URLs valid for 24 hours.

List all webhook subscriptions on your account. Returns webhook IDs, URLs, subscribed events, and creation dates.

Create a webhook subscription for event notifications. Events: screenshot.completed (batch job done), quota.warning (80% used), quota.exceeded (100% used). Max 5 webhooks per account. Payloads are signed with HMAC-SHA256. Save the returned secret to verify signatures.

Delete a webhook subscription by ID. This cannot be undone.

Send a test payload to a webhook endpoint to verify it receives events correctly. Returns the delivery status and HTTP response code.

Get current month's screenshot usage statistics including screenshots used, limit, and remaining quota.
