Python SDK for interacting with the Open Labels Initiative; A framework for address labels in the blockchain space. Read & write labels into the OLI Label Pool, check your labels for OLI compliance.

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.
- 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
For more details, see the OLI Documentation.
