Prices are computed in GBP. The selector converts the display value; the underlying transaction currency on cambridgetcg.com remains GBP.
Current collected upstream price history is CardRush only. TCGplayer is blocked under the access and use terms available to Cambridge; Cardmarket's public-file reader is planned.
Daily JP retail snapshot from cardrush-digimon.jp. Internal-only license: signed-in personal-decision use only.
Blocked: TCGplayer is not granting new API access, and its terms prohibit combining its prices with Cambridge or third-party prices without written consent.
Public daily Product Catalog and Price Guide files exist; Cambridge's file reader and field-level rights lineage are not wired yet.
CardRush's current boundary restricts compiled price-data redistribution, so its history remains signed-in and bounded. Cambridge has no recorded TCGplayer partner agreement; no TCGplayer observations or history are served.
The canonical SKU is the federation-stable identifier — a partner with this SKU can resolve through /api/v1/universal/card/dmw-st13-09-ja for the mixed-rights math-mirror representation (aggregate NOASSERTION). Cross-source comparison and federation reverse-lookup are documented in the methodology.
