/check endpoint accepts a document object describing the filing. Only page_count and word_count are required. All other fields are optional. The more you provide, the more checks run.
Required fields
With these two fields, the API checks page limits, word limits and courtesy copy requirements, and it checks word count consistency when
certificate_word_count is also provided.
Optional sections
caption
Enables FRCP 10(a) caption checks.
signature_block
Enables FRCP 11(a) signature checks.
sections
Enables structural checks: required documents, certificates, motion-specific requirements.
format
Enables district local rule formatting checks (font, margins, line spacing).
privacy
Enables FRCP 5.2(a) privacy redaction checks.
Omission principle
When an optional section is omitted, the corresponding checks are silently skipped. You can start with minimal input (just page and word count) and add detail as your document analysis improves. Themeta.checks_skipped field in the response tells you how many checks were skipped due to missing input.
