Fyi I built this for personal use tailored around Japanese cards. I scrape Yahoo Auctions, Mercari, Goldin, RareCandy, and a few other auction sites and send alerts based on keyword matching. Below is my search for anything Bakaboon related:
OR(
keywords["Bakaboon"],
AND(keywords["CoroCoro"], "2002 6"),
AND(
keywords["Battle Road"],
OR(keywords["Imakuni"], "2002"),
),
AND(
keywords["card"],
OR(
"こんな時代だからこそ",
"サチコは思わずタカオを",
"宇宙快速「ラピッドマスター」で",
"ビキニスタイルの",
"マーガレット・コズボーンが",
"群衆が",
"平家が",
"大家さんを",
"ルーファラ・コズボーンを",
"あの頃のオレを",
"封じ込め、そして平和がおとずれた",
"映画化",
"まだ勝負はわからないぜ",
"ものまねをやるのだ",
),
"bakudan",
)
)
Where keywords
maps to Japanese translations. So "バトルロード イマクニ"
on JP markets (or “Battle Road Imakuni” for English markets) would cause an alert to be sent to me.
I haven’t scoped out alerting on specific graded-cards. Most sites store the cert ID so it is easy to look up against pop reports. I assume desired behavior in your case is to select multiple cards from PSA and CGC pop reports and receive texts/email when any of them pop up across multiple marketplaces?
