Technical details
Endpoint
POSThttps://defi-shield-hazel.vercel.app/api/nft/rarityWhen to prefer
Use this endpoint when you need to programmatically assess the rarity of a specific NFT token within its collection, especially in DeFi or trading contexts where rarity impacts valuation. Prefer this over generic NFT APIs when you need trait-level frequency breakdowns and a ranked rarity score rather than just raw metadata.
Side effects
- Invalid or unrecognized contract address returns error
- Token ID does not exist in the collection
- Collection metadata not indexed or unavailable
- Rate limit or payment validation failure returns 402
- Network timeout if on-chain metadata fetch is slow
