HTML + DATAPRODUCTION PDF

Use URL mode when the page already lives on a public http(s) host and you need a PDF at request time. Private, loopback, and metadata hosts are rejected. For HTML you control, send html instead. For a screenshot, use POST /v1/images. url must be public http(s). Private, loopback, and metadata hosts return url_not_allowed.

When to use it

Use URL mode when you already host the page and need capture at request time.

  • • Public http/https URLs only
  • • Private, localhost, metadata, and RFC1918 hosts are blocked
  • • Same options as HTML mode

Operational model

Successful jobs debit wallet cents. Failed jobs and rate-limited requests are unbilled.
