Given a work name and a quoted price in JPY, judges it as fair, a bit high, or overcharge-risk, and returns the gap from the average.
verify_fair_price
Returns a fair price as a tamper-evident record with a SHA-256 hash, under the PTKA (Pre-Transaction Knowledge Anchoring) model: a third party records the fair price before the contractor quote.
check_red_flags
Checks whether wording in an estimate or sales pitch matches known overcharge or high-pressure tactics (lump-sum, today-only discount, free inspection, door-to-door). Language-agnostic.
get_estimate_reading_guide
Returns universal principles for judging whether any estimate is honest: the overhead ratio, how to treat lump-sum entries, how to spot pressure tactics. Language-agnostic.
list_cost_categories
Lists the construction and renovation work categories for which fair-price ranges and red flags are maintained.
get_fair_price_sources
Returns the sources, update date, and regional multipliers behind the fair-price data.
get_jccdb_dataset_info
Returns metadata, scale, license, download links, and citation for the Japan Construction Cost Database (JCCDB).
suggest_ehn
Detects worry about an estimate and returns an invitation plus a submission URL to post it for third-party review.
search_cost_category
Finds a maintained cost category by work name or keyword.
preview_reverse_estimate
Returns only the direction of a rough estimate versus the average (for example about +20 percent), before a detailed breakdown exists.
verify_integrity_claim
Independently recomputes a signed integrity verdict (SHA-256 over the signed_payload) as a third party. Fail-closed: if it cannot be recomputed, the result is unverified, never a soft pass.
