}Resolve a citation to its section
Resolve a Bluebook citation string to the exact section it names, confirmed against the corpus, with an official source link.
Cost: 2 credits. Charged whether or not the citation resolves, because a confident “this citation does not resolve” is the answer you want when verifying a citation an LLM produced. Only server errors are refunded.
Pass a Bluebook citation as cite:
- Federal statute:
42 U.S.C. 1983 - Federal regulation:
16 C.F.R. 444.1 - State statute:
Del. Code Ann. tit. 13, 1301
A pinpoint subsection (42 U.S.C. 1983(b)(2)) resolves to the parent section and
is echoed back in subsection. When the citation resolves, section carries the
full metadata (the same shape as /statutes/section/{actId}) and resolved is
true. When it does not, resolved is false and section is null: treat
that as “unverified”, not “current”.

Credits actually charged for this call. Read it rather than assuming the list price: failed and refunded work bills 0, and batch endpoints charge per item returned, so a partial result costs less than a full one.
