Returns the current merchant offers of one product (product_id, product slug or edition_id; region JP by default): price in integer minor units with currency_exponent plus price_display (the same amount formatted, e.g. ¥29,700, or 無料 for a price of zero), tax and shipping status, seller class, presentation_state (active, ending_soon, stale, scheduled, unverified), price_certainty, checked_at, fresh_until and expires_at. Prices are observations with a verification state, not guarantees. An offer past fresh_until has presentation_state stale: its price is the last checked price (see checked_at) and it is not a basis for a lowest price, budget fit, cheapest cost or list_deals prices_from; expired offers are not returned. An offer priced in another currency may carry converted (a yen estimate: amount_minor, display such as 約¥7,800, rate_source ecb_eurofxref, rate_reference_date, rate_basis direct or cross_via_eur, and basis_note, a fixed English sentence saying that this site computed the estimate from the European Central Bank's reference rates of that date and that it is not a price) that is not used for ordering, budget fit, cheapest cost or lowest_observed. field_availability.offers is not_recorded when no offer of the product has been recorded. customer_segment is general, or existing_owner, education or nfr for a row the store names as an upgrade, crossgrade, update, EDU or NFR edition (maker and distributor names are not read). Rows that are not general stay in this list with their segment and are not used for a product's default price, lowest price, list_deals prices_from or largest_discount_percent; lowest_observed has no element for editions named upgrade, crossgrade, update, EDU or NFR. A price or listing that a source keeps off this channel is marked withheld_by_channel_policy (offers_coverage=partial) and is not estimated; Rakuten Ichiba listings, for example, appear only on the web page. Each offer's permitted_handoff_links contains canonical_page and site_entry_page, and merchant_plain only where the source permits link distribution on this channel. An optional lowest_observed[] gives, per edition with price history, the window minimum (window_min_amount_minor, window_min_observed_at, observed_since, missing_days, merchant_count, basis_ja) and names the current offer when it is the lowest price seen so far (current_is_lowest_so_far, label_tier high / probable, label_ja, rule_id). current_is_lowest_so_far is true, false or null; null comes with lowest_so_far_undetermined_reason (no_current_price, current_offer_not_on_this_channel, no_price_drop_observed or not_comparable), and false means the current price is above the window minimum. window_min_display is the window minimum formatted. The window minimum is the lowest of our own observations and recorded external references, stated with its basis; it is not a vendor list price or a regular price. An offer of a subscription or rent-to-own edition carries billing_period (month or year): its price is the charge for one period, and it has no reference_price or discount_rate_bps; field_availability.billing_period is unknown when the period is not verified. Such editions have no lowest_observed element. A bundle product with a complete member list carries bundle_cards[]: per shop and currency, the bundle price, each included single product with its verified price at the same shop (amount_minor null with excluded_reason when there is none; never estimated), break_even_count (bundle price divided by the median single price, two decimals, rounded half up), discount_vs_singles_bps (the bundle price against the sum of the priced single prices in basis points, floored; negative when the bundle costs more than the singles; computed over members_priced of members_total), the formula with its inputs, snapshot_id and computed_at. An optional price_record[] gives, per edition and currency, the lowest price observed in the stated window and the last observed price drop at a shop, with the days since each; it records observations and is not a forecast. canonical_page is the product page on this site; it carries the complete price table (including listings withheld on this channel), the merchant purchase links and the affiliate disclosure. site_entry_page is the same page with the entry marker for this channel. Read-only; no purchase execution. Links are user_navigation handoffs (handoff_mode=user_navigation) and are not intended for prefetching or automatic clicking.
