# Address Labels

Retrieves all entity and behavioural labels associated with an address on a chain.

### Data Freshness & Historical Coverage

For data freshness and historical coverage, see [Data Coverage by Chain](/api/data-coverage.md); this endpoint follows it except where noted below.

* Returns the **current set of labels** for an address — there is no date-range parameter or historical look-back; labels reflect Nansen's latest label data and update within the standard live latency.

### Empty results and credit charges

Both endpoints return HTTP `200` with `data: []` when no eligible labels match the request. A successful empty response costs **0 credits**, including an empty page after the last result. A nonempty response costs **100 credits** for `/labels` or **500 credits** for `/premium-labels`.

The balance check happens before the lookup. You still need at least 100 or 500 credits respectively to make the request. `X-Nansen-Credits-Cost` quotes that upfront amount; `X-Nansen-Credits-Used` reports the actual charge, which is `0` for an empty response. This rule applies to plan credits. Separate pay-per-request payments retain their own pricing.

Labels are scoped to chains. An address can have labels on Ethereum and none on BNB, even though the address format is valid on both. Use `chain: "all"` to search all chains compatible with the address format.

When the lookup finds no rows on the first page for a specific EVM chain, both endpoints return the same generic hint:

```json
{
  "data": [],
  "hint": "Try chain: \"all\". No API credits were charged for this call."
}
```

The example omits the usual pagination fields. This suggestion is returned regardless of whether labels exist on another chain. The response does not include a list of available chains. Requests using `chain: "all"`, non-EVM addresses, and empty later pages do not receive this hint.

`chain: "all"` returns one combined list of eligible labels across chains compatible with the address format. Each label has `label`, `category`, and `kind`; labels are not grouped by chain. To retrieve labels for a particular chain, request that chain explicitly. Nonempty responses retain the endpoint's 100/500-credit price.

Other reasons for an empty response include an address with no known labels, premium-only labels excluded by `/labels`, and exhausted pagination.

`/premium-labels` can return a derived address name even when no labels are scoped to the requested chain. A response containing that name is nonempty and costs 500 credits.

## Retrieve address label data

> 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.nansen.ai/api/profiler/address-labels.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
