How this service works
Paid d402 capability alias for web.render_snapshot@1. Workers render a page in a browser and return snapshot and screenshot content IDs.
Output
Returns a task ID and status, plus a result object containing the rendered page URL, a snapshot CID (content identifier for the HTML snapshot), an optional screenshot CID, a SHA content hash, page title, HTTP status code, render timestamp, and viewport info. Links to the task, result, and payment receipt are also provided.
Example use cases
Example prompt
“Render https://example.com/product/123 in a browser and give me a full-page screenshot snapshot with the content hash as evidence — use a 1280x720 viewport and wait up to 20 seconds.”
Technical details
Endpoint
POSThttps://gateway.d402.xyz/v1/web/render-snapshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need tamper-evident, browser-rendered proof of a webpage's visual appearance and content at a specific moment — especially for archival, compliance, or dispute resolution. Prefer it over plain HTTP fetches when JavaScript-rendered content must be captured, or when a cryptographic content hash plus screenshot are required as evidence. Use when you need both the visual screenshot and a verifiable content fingerprint together.
Side effects
- URL is not publicly accessible or returns non-200 → error status with error message
- Timeout exceeded (max 45000ms) before page finishes loading → error status
- waitForSelector never appears within timeout → error or incomplete snapshot
- Invalid URL format → request rejected with validation error
- Page renders but screenshot capture fails → screenshotCid is null
- Network or worker infrastructure failure → error status
