Two helper endpoints serve the raw material behind posts: cached page snapshots and collected images. Both use ready-made URLs returned inside posts - you never build the id yourself.
When a cached snapshot exists, the post's cache_link field holds a ready-made relative URL. Append it to the base URL and call it:
GET
https://api.webz.io/dark-cache?token=YOUR_TOKEN&id=...
cache_link is null when no snapshot is available - for example, for non-HTML files.
Image URLs inside a post's extended.external_images[].url point to the image endpoint:
GET
https://api.webz.io/cyber-image?token=YOUR_TOKEN&id=...
Both endpoints require Dark Web API permission and consume 1 credit per request, like a search - see Errors, Rate Limits & Credits.
