The Merkle proof of one compressed NFT, Solana only

The inclusion proof of a Solana compressed NFT — tree, root, leaf, node index and Merkle path — that a transfer, burn or redemption of it must carry.

What it returns

Returns the inclusion proof of one Solana compressed NFT: the tree holding it, the root the proof verifies against, the leaf hash, the leaf's node index and the Merkle path. A transfer, burn, delegation or redemption of a compressed NFT must carry this proof. found: false is a full answer, not an error: the id is not a compressed NFT the index holds (a regular NFT, a token mint, a burnt asset or no asset at all). The proof ages with the tree — every mint, transfer or burn in the same tree moves the root — so submit it promptly or ask again.

Parameters
Parameter	Description
`chain` path · string · required	SOL. Every other chain returns 400: compressed NFTs are leaves of a Solana concurrent Merkle tree.
`address` path · string · required	The compressed NFT's asset id, base58 — the id wallets and marketplaces show for it (a compressed NFT has no mint account).

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of The Merkle proof of one compressed NFT, Solana only
Field	Type	Description
`asset`	string	The asset id asked about.
`found`	boolean	True when the id is a compressed NFT the index holds a proof for.
`indexedSlot`	integer \| null	The slot the index had reached when it answered; null when nothing was found.
`proof`	object \| null	The inclusion proof. Null whenever `found` is false.
`proof.tree`	string	The Merkle tree holding the NFT's leaf.
`proof.root`	string	The tree root this proof verifies against.
`proof.leaf`	string	The leaf hash.
`proof.nodeIndex`	integer	The leaf's node index in the tree's heap numbering: 2 to the tree depth, plus the leaf's position.
`proof.path`	string[]	The sibling hashes from the leaf up to the root, bottom first; as many as the tree is deep.
