# How to Get CSFloat Sale Volume

> `POST /v1/archive/csfloat` returns CSFloat daily completed-sale `volume` from 2022 onward, paired with the day's average sale `price`.

Sale volume counts completed purchases. It is different from `ask_volume`, which counts listings that remain active.

## CSFloat volume fields

Every returned UTC day contains:

| Field | Meaning |
| --- | --- |
| `date` | Calendar date of the aggregate |
| `price` | Arithmetic average completed-sale price in USD |
| `volume` | Number of completed sales |

The series refreshes once or twice per day. Doppler and Gamma Doppler phases can have their own sale series under `variants` when archive data exists. Case Hardened tier sale histories are not collected.

## Query daily sale counts

Send exact `market_hash_name` values and a date range to `POST /v1/archive/csfloat`. The endpoint accepts up to 100 items and supports partial success through `errors[]`. Read the requested item's chronological `data[]` rows and sum `volume` only across the dates relevant to the analysis.

For supported Doppler and Gamma Doppler variants, request the base item and match the desired `version` under `variants`. Parent volume must not be counted once for every phase.

If the task needs a current listing count, use `ask_volume` from `GET /v1/prices/latest` and label it separately. The [CSFloat sales history guide](/resources/how-to-get-csfloat-sales-history) covers using price and volume together.

## Applicable endpoints

| Endpoint | Returns | Plans |
| --- | --- | --- |
| `POST /v1/archive/csfloat` | Daily completed-sale average and count | Scale, Enterprise |
| `GET /v1/prices/latest` | Current listing count | All plans |

## Keep in mind

- Days without a returned aggregate are absent, not zero-sale observations.
- `price` is an arithmetic average, so multiplying it by `volume` can support weighted summaries but does not recover individual sale prices.
- Sparse phase days can mix different float, seed, and sticker premiums.
- The archive end boundary is exclusive and dates are UTC.

The [CSFloat archive reference](/docs/api-reference/archive-csfloat) defines the response and archive error codes.
