How this service works
Get labels for a wallet address. Returns non-premium labels only. Labels include ENS domains, behavioral labels, DeFi labels, CEX labels, and more. Premium labels (smart money, alpha trader) are excluded from this endpoint. Use /api/v1/profiler/address/premium-labels to get all labels including premium ones. Successful empty responses cost 0 credits; nonempty responses cost 100 credits. The upfront balance check still requires 100 credits. Empty first pages for a specific EVM chain may include a generic hint to use chain="all". The hint does not report whether labels exist on other chains. Empty later pages are also free.
Output
A paginated list of label objects for the queried wallet address, each containing a label name (e.g. 'Token Millionaire', 'nansen.eth') and a category (e.g. 'behavioral', 'social', 'defi', 'cefi', 'nft'). Only non-premium labels are returned. Pagination metadata indicates the current page and whether it is the last page.
Example use cases
Example prompt
“Look up the Nansen labels for the Ethereum wallet 0x4a7c6899cdcb379e284fbfd045462e751da4c7ce — I want to see its behavioral, DeFi, and ENS labels, page 1 with up to 100 results.”
Technical details
Endpoint
POSThttps://api.nansen.ai/api/v1/profiler/address/labels?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly classify or enrich a wallet address with publicly available, non-premium Nansen labels such as ENS names, behavioral tags, DeFi participation, or CEX affiliation. Prefer this over the premium-labels endpoint when smart money or alpha trader labels are not needed and cost or access constraints apply.
Side effects
- Invalid or unsupported chain enum returns a validation error
- Malformed wallet address format causes a 400 bad request
- Address with no labels returns an empty data array
- Pagination page beyond available results returns empty data with is_last_page=true
- Missing required fields (address or chain) returns a 422 unprocessable entity
