Near Blockchain
Overview
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)
