Find cross-book arbitrage in a fixture — a guaranteed-profit price split — in ONE call. Resolves the fixture, then for each market/line takes the best price per outcome across books; when the inverse prices sum to < 1 there is a locked margin regardless of result. Reports the margin % and which book holds each leg (legs must come from ≥2 distinct books). DETECTION ONLY: no stake sizing, no bet links — InferSports is read-only. Args: query: natural-language fixture, e.g. "Netherlands vs Algeria" or a single team. markets: optional filter — any of "1x2", "asian_handicap", "totals" (default: all). period: optional — "full_time" or "half_time" (default: both). min_margin_pct: only report opportunities with at least this guaranteed margin (default 0). format: odds format — decimal | hk | malay | american | indonesian | probability. sport: optional filter — "football" or "basketball". date: optional UTC date "YYYY-MM-DD" to disambiguate same-name fixtures. On an ambiguous query, ``status`` is "ambiguous" and ``ask_user`` carries a prompt — do not guess.
