Direct Answer
Use a wallet labels API when an agent needs address labels, entity attribution, wallet portfolio context, counterparty tags, or risk-screening evidence before deciding what to fetch next. Wallet and portfolio APIs such as Moralis and Zerion fit balances, positions, and account activity; entity-intelligence or analytics sources such as Nansen, Allium, and Chainbase fit labels, clusters, holders, and attribution evidence; direct address-label docs such as MetaSleuth, Formo, or Mobula need provider-profile review before being treated as durable sources; compliance-oriented sources such as Scorechain, TRM Labs, Elliptic, and Sanctions.io fit screening or risk-context workflows. PubFi Discovery maps those source classes and keeps public source inclusion separate from live PubFi routeability.

- Safe citation boundary
- Indexed-only. Use this page to compare wallet-label, wallet-portfolio, on-chain analytics, and screening sources by public evidence, chain coverage, auth, and agent-readable contract shape. Discovery inclusion is source-selection evidence only; it is not a claim that PubFi provides a universal wallet-label gateway, supplier route, or automated risk decision system.
- Evidence boundary
- Ranking and public citation claims require current public evidence; this page does not claim those outcomes by itself.
