OLI Python SDK

oli-python is the official Python SDK for the Open Labels Initiative (OLI), a framework for standardized and trusted blockchain address labels.

This SDK lets you read, write, validate, and revoke address labels within the OLI Label Pool and compute confidence scores based on attesters' relationships within the OLI Label Trust.

Video Walkthrough

Installation

pip install oli-python

Initialization

from oli import OLI
import os

# Initialize the client
oli = OLI(
    private_key=os.getenv("PRIVATE_KEY"),
    api_key=os.getenv("OLI_API_KEY")
)

Setup Instructions:

• Create a .env file to store your private variables
• Load an EOA wallet by setting the private_key variable
• The EOA wallet is used to track your reputation within OLI
• To access all advanced API endpoints, pass an api_key variable. You can get your free API key from here

Additional Options:

You can also set the chain parameter to specify which EAS contracts location to use and the custom_rpc_url variable when initializing.

Submit Labels into the OLI Label Pool

Single Attestation

# Define your OLI compliant attestation
address = "0x9438b8B447179740cD97869997a2FCc9b4AA63a2"
chain_id = "eip155:1"  # Ethereum mainnet
tags = {
    "contract_name": "growthepie donation address",
    "is_eoa": True,
    "owner_project": "growthepie",
}

# (Optional) Validate your attestation before submission
is_valid = oli.validate_label(address, chain_id, tags)
print("Your attestation is OLI compliant:", is_valid)

# Submit label to the OLI Label Pool
response = oli.submit_label(address, chain_id, tags)
print(response)

Bulk Attestation

attestations = [
    {"address": address, "chain_id": chain_id, "tags": tags},
    {"address": address, "chain_id": chain_id, "tags": tags},
]

response = oli.submit_label_bulk(attestations)
print(response)

Revoke Attestations

Note: All revocations are onchain transactions and therefore require you to have ETH on Base for gas in your wallet.

# Revoke a single attestation
oli.revoke_by_uid(uid="0x...")

# Bulk revocation
uids = ["0x1...", "0x2..."]
oli.revoke_bulk_by_uids(uids)

Reading the OLI Label Pool

Get Raw Attestations

response = oli.get_attestations()
print(response)

Available filters: uid, attester, recipient, schema_info, since, order, limit

Get Labels for an Address

# All labels for an address
response = oli.get_labels(address = "0x9438b8B447179740cD97869997a2FCc9b4AA63a2")
print(response)

Available filters: address, chain_id, limit, include_all

Bulk Get Labels for Addresses

addresses = ["0x9438b8B447179740cD97869997a2FCc9b4AA63a2", "0x4752ba5DBc23f44D87826276BF6Fd6b1C372aD24"]
response = oli.get_labels_bulk(addresses)
print(response)

Available filters: addresses, chain_id, limit_per_address, include_all

Get Addresses Based on a Tag

response = oli.search_addresses_by_tag(
    tag_id="owner_project",
    tag_value="growthepie"
)
print(response)

Available filters: tag_id, tag_value, chain_id, limit

Attester Leaderboard

chain_id = "eip155:1"
stats = oli.get_attester_analytics(chain_id)
print(stats)

OLI Label Trust

# Set a new source node for trust propagation
trust_table = oli.set_trust_node("0xYourAddress")
print(oli.trust.trust_table)

# Import your trust list from YAML file
import yaml
with open('example_trust_list.yml', 'r') as file:
    trust_list = yaml.safe_load(file)
    owner_name = trust_list.get('owner_name')
    attesters = trust_list.get('attesters', [])
    attestations = trust_list.get('attestations', [])

# Check if the trust list is OLI compliant
is_valid = oli.validate_trust_list(
    owner_name, 
    attesters, 
    attestations
)
print("Your trust list is OLI compliant:", is_valid)

# Add a private trust list to the trust graph
oli.add_trust_list(
    owner_name, 
    attesters, 
    attestations
)

# Submit your trust list to the global trust graph
response = oli.submit_trust_list(
    owner_name, 
    attesters, 
    attestations
)
print(response)

Once you set your trust node or submit your trust list, the transitive trust algorithm can assign a trust score to all labels. Use the following endpoints, which now assign a confidence score to each label. You can also set min_confidence to filter based on confidence thresholds.

Get Trusted Labels for an Address

# All trusted labels for an address
response = oli.get_trusted_labels(address = "0x4752ba5DBc23f44D87826276BF6Fd6b1C372aD24")
print(response)

Available filters: address, chain_id, limit, include_all, min_confidence

Bulk Get Trusted Labels for Addresses

addresses = ["0x9438b8B447179740cD97869997a2FCc9b4AA63a2", "0x4752ba5DBc23f44D87826276BF6Fd6b1C372aD24"]
response = oli.get_trusted_labels_bulk(addresses)
print(response)

Available filters: addresses, chain_id, limit_per_address, include_all, min_confidence

Get Trusted Addresses Based on a Tag

response = oli.search_trusted_addresses_by_tag(
    tag_id = "owner_project",
    tag_value = "growthepie"
)
print(response)

Available filters: tag_id, tag_value, chain_id, limit, min_confidence

OLI Label Pool Parquet Exports

growthepie provides dataset exports as Parquet files for all attestations inside the OLI Label Pool, updated daily:

oli.get_full_raw_export_parquet()
oli.get_full_decoded_export_parquet()

Option: Pass the filepath as a variable to store the export in a specific location.
