Bid Protest Nexus

Corpus coverage and valid filter values: decision counts by outcome and record type, year range, contracting vehicles, most common agencies, how each filter matches, and known data caveats.

corpus_info

Decisions most similar to a given B-number. Without filters, the first five are re-ranked by an LLM for the same core legal issue (better than raw similarity) and the rest follow by document similarity. With filters, every decision that passes them is ranked by document similarity. Use opposite_outcome to find contrary results and exclude_same_docket to skip the same protest's other decisions.

find_similar_decisions

The analysis of one GAO bid protest decision by B-number: date, agency, outcome_assessed (authoritative disposition from the decision text), summary, issues, reasoning, outcome rationale, key points, the GAO source URL when known, and its five most similar decisions. Consolidated decisions resolve from any of their B-numbers.

get_decision

A stored comparison of a decision with its five closest matches: shared issues, differences, grounds to distinguish, practical use, matched passage pairs from the full texts, and FAR, U.S.C. and GAO citations that appear in both decisions. Not every decision has one; if missing, use find_similar_decisions.

get_similarity_synopsis

Semantic search over GAO bid protest decisions. Describe a legal issue or fact pattern in plain language (for example 'bid bond missing at bid opening' or 'agency failed to evaluate price realism'). Returns the closest decisions with similarity score, date, agency, outcome_assessed, a one-sentence core issue, summary and issues. Optional filters narrow the corpus before ranking.
