Near Blockchain

The intention of this notebook is to provide a means of testing functionality in the Langchain Document Loader for Near Blockchain.

Initially this Loader supports:

• Loading NFTs as Documents from NFT Smart Contracts (NEP-171 and NEP-177)
• Near Mainnnet, Near Testnet (default is mainnet)
• Mintbase's Graph API

It can be extended if the community finds value in this loader. Specifically:

• Additional APIs can be added (e.g. Tranction-related APIs)

This Document Loader Requires:

• A free Mintbase API Key

The output takes the following format:

• pageContent= Individual NFT
• metadata={'source': 'nft.yearofchef.near', 'blockchain': 'mainnet', 'tokenId': '1846'}

Load NFTs into Document Loader

# get MINTBASE_API_KEY from https://docs.mintbase.xyz/dev/mintbase-graph/

mintbaseApiKey = "..."

Option 1: Ethereum Mainnet (default BlockchainType)

from MintbaseLoader import MintbaseDocumentLoader

contractAddress = "nft.yearofchef.near"  # Year of chef contract address


blockchainLoader = MintbaseDocumentLoader(
    contract_address=contractAddress, blockchain_type="mainnet", api_key="omni-site"
)

nfts = blockchainLoader.load()

print(nfts[:1])

for doc in blockchainLoader.lazy_load():
    print()
    print(type(doc))
    print(doc)
