Installation

pip install oli-python

Submitting New Labels

from oli import OLI
import os

# Initialize the client
# Make sure to pull in your private key from an .env file
oli = OLI(private_key=os.environ['OLI_PRIVATE_KEY'], is_production=True)

# Create an offchain label
address = "0x9438b8B447179740cD97869997a2FCc9b4AA63a2"
chain_id = "eip155:1" # Ethereum Mainnet
tags = {
    "contract_name": "growthepie donation address",
    "is_eoa": True,
    "owner_project": "growthepie"
}

# Validate if your label is OLI compliant
possible_to_attest = oli.validate_label_correctness(address, chain_id, tags)
print(f"You can attest your label: {possible_to_attest}")

# Submit a label as an offchain attestation
response = oli.submit_offchain_label(address, chain_id, tags)
print(f"Attestation created: {response.text}")

# Submit a label as an onchain attestation
tx_hash, uid = oli.submit_onchain_label(address, chain_id, tags)
print(f"Transaction hash: {tx_hash}")
print(f"Attestation UID: {uid}")

# Batch submit multiple labels as one onchain attestation
labels = [
    {'address': address, 'chain_id': chain_id, 'tags': tags},
    {'address': address, 'chain_id': chain_id, 'tags': tags}
]
tx_hash, uids = oli.submit_multi_onchain_labels(labels)
print(f"Batch transaction hash: {tx_hash}")
print(f"Attestation UIDs: {uids}")

# Revoke an attestation (revoking onchain attestations here)
trx_hash = oli.revoke_attestation(uid, onchain=True)

# Revoke multiple attestations (revoking onchain attestations here)
trx_hash, count = oli.multi_revoke_attestations(uids, onchain=True)

Querying Existing Labels

from oli import OLI
import os

# Initialize the client (read only mode doesn't require a private key)
oli = OLI(is_production=True)

# Query attestations for a specific address
result = oli.graphql_query_attestations(address=address)
print(result)

# Download parquet export of raw attestations
oli.get_full_raw_export_parquet()

# Download parquet export of decoded attestations
oli.get_full_decoded_export_parquet()

Wallet Requirements

The OLI Label Pool lives on Base as an Ethereum Attestation schema.

Make sure your wallet contains ETH on Base Mainnet to pay for onchain transaction (including offchain revocations). Offchain attestations are free.

For testing purposes, you can use Base Sepolia Testnet by setting is_production=False when initializing the client.

Features

• Submit onchain (single or batch) and offchain (single) labels into the OLI Label Pool
• Revoke your own labels (single or batch)
• Validate if your label is OLI compliant
• Query attestations using GraphQL
• Download full dataset exports in Parquet format
