# Historical Address Transactions

## Get Historical Transactions for an Address (Beta)

> \*\*Beta — subject to breaking changes.\*\*\
> \
> Returns the 20 most recent token transfer transactions for a wallet address as\
> of a historical snapshot date, with temporally-correct counterparty labels.\
> \
> \*\*Key differences from \`/profiler/address/transactions\`:\*\*\
> \- Accepts an explicit \`as\_of\_date\` (no rolling default)\
> \- Counterparty labels resolved from label history at \`as\_of\_date\` (no forward-looking bias)\
> \- Limited to ethereum, base, bnb, and solana\
> \- Capped at 20 results per query

## Get Historical (Time-Travel) Transaction Lookup Data (Beta)

> Time-travel-aware variant of \`/transaction-with-token-transfer-lookup\`.\

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nansen.ai/api/backtesting-data/historical-address-transactions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
