split_html

document

Break a long HTML document into separate files — by heading level, by a custom delimiter, or by page break. Each section comes back as its own signed download URL.

When to use: A single large HTML export needs to become one file per chapter or section.
Not for: Turning HTML into a PDF (html_to_pdf). Splitting a PDF (split_pdf).
Returns: A list of HTML fragments, each with a filename and a signed download URL.

Parameters

Name	Type	Required	Description
file_url	string	no	Public http(s) URL of the input file (preferred — fetched server-side, so the bytes never pass through your context). Private, loopback and cloud-metadata addresses are blocked.
file_base64	string	no	Base64 of a small inline input file (up to about 15MB). Provide "filename" too.
filename	string	no	Original filename including its extension, e.g. "report.pdf". The extension is how the source format is detected.
html	string	no	Raw HTML to split, instead of a file.
split_by	string	no	Where to cut the document. (h1, h2, h3, hr, page-break, custom)
custom_delimiter	string	no	The delimiter to cut on when split_by is 'custom'.
output_base_name	string	no	Base name for the produced files.
