# Historical Smart Money Positions

{% hint style="info" %}
**Note:** This is a beta endpoint (`/api/v1beta1/`). Request shapes, response fields, and pricing may change as we iterate.
{% endhint %}

### Data Freshness & Snapshot Timing

This endpoint returns **point-in-time daily snapshots** keyed by `as_of_date`. Each snapshot represents **end-of-day UTC** values for that date.

* **Daily snapshots only — the current day is excluded.** Querying `as_of_date = today` (or any date whose snapshot has not yet been produced) returns an empty `data` array with HTTP 200 — never a live or partial current-day result.
* **Settlement timing.** A given day's snapshot is produced by a daily batch the following morning (UTC); exact timing varies. Until that batch completes, the prior day returns empty, so in the early-UTC hours the freshest available snapshot may be two days back. Rather than assuming a fixed availability time, query the date you need and fall back to the previous day (or retry later) if it comes back empty.

## Get Historical SM Token Balances (Beta)

> \*\*Beta — subject to breaking changes.\*\*\
> \
> Point-in-time smart money token balance aggregates for a given date.\
> \
> Returns SM token holdings per (chain, token\_address) pair filtered by SM labels,\
> token type, and chain. Includes 24h balance change, holder counts, share of total\
> SM holdings, and historical market cap.\
> \
> Results are computed from historical datasets at request time and may change\
> after late data, pricing fixes, label-history corrections, sector changes, or\
> token metadata updates.

# 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-smart-money-positions.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.
