Foils

[Piotr]

They do not provide it in their API.

I wouldn't bother with MT if TCG provided.

[Keyeto]

Because TCG does not provide. Does it?

Like NyghtHawk mentioned above me, tcgplayer has foil prices, and a "foil" filter option which shows you only the foil prices. I have had a problem with it though, as some cards that are only printed in foil don't say foil on them. Specifically, the {Liliana Vess} from the duel decks. That version of her is foil, but not all the options said "foil" next to the card's condition.

I don't where the foil prices come from some cards foil prices are way lower than non foil and some are way higher

Is there any other site you could get foil prices from that are more accurate?
Most of the time I just would look at the normal price and the rarity and then depending in how rare or common it is add different amounts that seem reasonable like 25-75 cents for most commons and do on

TCGplayer does not provide foil prices in their API.

Magic Traders prices we use for foils come from eBay, so it makes perfect sense that sometimes they are cheaper than inflated prices from non-foil TCGplayer which come from retail shops.

TCGplayer emailed me today:

"We have a few API changes planned that I want to explain and gather your feedback on!

The first announcement is something I am sure you will enjoy... we are finishing up foil Magic card prices for the API. Once it is ready in the next few weeks we will be making the updated API available to each of you. This will most likely be the Magic Foil Median Price only.

So we are getting more accurate foil prices?

[Piotr]

I suppose.

[NyghtHawk]

Sounds good. Besides more accurate there will be more in general as tcg generally had most fools prices for all cards. Magictraders does not.
