Rarity model

royalty

Array of 0 or more royalty details, by source. Different marketplaces allow for different royalty amounts, so we show a list of the available information. When there are multiple sources, we list them from highest to lowest total_creator_fee_basis_points.

Current sources are: opensea, metaplex, erc2981

The list of recipients can have 0 or more wallets, as applicable. Amounts are shown in both basis_points (adding up to total_creator_fee_basis_points) and percentage, which is the share of this wallet's fees compared to other recipients.

Note that for the recipients list, OpenSea natively uses basis_points while Metaplex uses percentage, so if you need very precise amounts (i.e. no possibility of rounding), use basis_points for OpenSea & ERC2981 and percentage for Metaplex.

[{
source: string,
total_creator_fee_basis_points: int,
recipients: [{
address: string,
percentage: float,
basis_points: int
}][{
`address: string, \percentage: float, \basis_points: int`
}]
}]
