POST/jp-address/postal-lookup$0.001Japanese postal-code lookup and reverse lookup. Keywords: Japanese postal lookup, Japan Post postal code, postal code reverse lookup, 日本郵便番号検索. Use a postal code or prefecture/city/ward/town components against the local Japan Post snapshot. / 通过邮编或都道府县、市区町村、区、町名字段，在本地 Japan Post 数据中进行日本邮编反查。
POST/jp-address/validate$0.005Japanese address validation and quality decision. Keywords: Japanese address validation, address conflict, address quality, partial match, 日本住所検証. Validate parser, postal, and geocoder evidence using one address policy, returning exact, partial, ambiguous, conflict, or unverified status with the accepted hierarchy and reasons. / 使用统一规则合并解析、邮编和地理编码证据，并返回完全一致、部分一致、歧义、冲突或未验证状态。
POST/v1/invoices/counterparty-check$0.05Check a known EU VAT ID and/or Peppol participant using separate tax-validity, entity-match, and discoverability evidence. VIES is never used for name search and upstream responses are not resold. / 既知のEU VAT IDまたはPeppol参加者を税番号有効性・法人一致・到達性に分けて確認します。VIESは名称検索に使わず、元データは再販しません。
POST/jp-address/geocode$0.005Japanese forward geocoding from an address to coordinates. Keywords: Japan geocoder, address to coordinates, building-level geocode, Jageocoder, chome, block, lot, house. Returns provider-neutral local candidates, coordinates, address IDs, hierarchy levels, unmatched tails, and partial-match warnings. Jageocoder level 5/6 is oaza/aza, level 7 is block, and level 8 is a building or house node when present in the dictionary; town-level evidence is not a door-number or coordinate accuracy claim.
POST/jp-address/parse$0.005Japanese address parser and component extraction. Keywords: Japanese address parser, address components, chome, block, lot, house, 丁目, 番地, 号. Parse a Japanese address into components without returning postal validation or geocoding; local postal prefix evidence may safely recover a unique town or report ambiguity. / 日本住所を構造化します。郵便番号の検証結果・ジオコーディングは返しませんが、町域の一意な前方一致による補完・曖昧性判定のためローカル郵便データを内部参照する場合があります。
POST/v1/entities/resolve-cross-border$0.04Resolve a JP or GB entity using projected official evidence from NTA/gBizINFO or Companies House; raw upstream responses are not returned. Hard identity conflicts are never verified. / 日本または英国の企業を公式根拠の加工済み投影で確認します。元データは返さず、識別子の矛盾はverifiedになりません。
