Is OpenRarity supported?

No, Reservoir does not support OpenRarity ranks at this time. For a rarity score, we use PopRank's NFT rankings that you can learn more about here.

We return both rarity and rarityRank in the tokens API (GET /tokens).

• rarity is a score based on the frequencies of each trait given to each token within a collection.
• rarityRank is a rank given to each token within a collection based on their rarity. In most cases, we recommend using rarityRank.

Please note that as rarity is based on trait frequency, collections with few or no traits will not provide accurate rarity or rarityRank data.
