# each::storage Overview

> Host the media you send to and receive from each::labs — upload files, get stable URLs, and use them anywhere on the platform.

## What is each::storage?

each::storage is managed file hosting for the media that flows through each::labs. Upload an image, video, or audio file once and get back a stable public URL you can pass straight into [each::api](/api/overview) predictions and [each::workflows](/workflows/overview) — no need to stand up your own bucket or CDN.

It's also the layer each::labs uses to deliver results: model and workflow outputs are typically (though not always) served as `cdn-us.eachlabs.ai` URLs, so the files you upload and the results you get back share one fast, consistent host.

## Why use it

* **No infrastructure to run** — skip hosting and signing your own uploads; we hand you a presigned URL and a stable public link.
* **Built for model inputs** — returned URLs are reliably fetchable by our executors, so predictions don't fail on inaccessible media.
* **One platform, one key** — uploads use the same `X-API-Key` as the rest of each::api.
* **Fast delivery** — files are served from a CDN over HTTPS.

## How it works

<Steps>
  <Step title="Request a presigned URL">
    Call [Upload File](/storage/upload-file) (`POST /v1/upload/presign`) with the file's content type. You get a short-lived upload URL plus a public `public_url`.
  </Step>

  <Step title="Upload the bytes">
    `PUT` the raw file to the presigned URL. A `200 OK` means it's live.
  </Step>

  <Step title="Use the URL">
    Pass `public_url` as an input to any model or workflow. Call [Delete File](/storage/delete-file) when you no longer need it.
  </Step>
</Steps>

## Browse & filter your files

Every file you upload or that a model generates shows up on the [storage page](https://eachlabs.ai/storage) in your dashboard. Filter by **model**, file type, source (uploaded inputs vs. generated outputs), execution, or date range to find exactly what you need.

## Limits

| Limit                  | Value                                                                |
| ---------------------- | -------------------------------------------------------------------- |
| Max file size          | 100 MB per upload                                                    |
| Presigned URL lifetime | 15 minutes                                                           |
| Stored file retention  | 180 days (default, configurable per upload via `expires_in_seconds`) |
| Supported file types   | `image`, `video`, `audio`, `other`                                   |

## Where your data resides

Files are stored in the **United States** and delivered through the `cdn-us.eachlabs.ai` CDN over HTTPS.

## Access & privacy

Each `public_url` contains an unguessable identifier but is readable by anyone who has the link — treat it as public. File management is scoped to your organization through your API key: you can only delete files uploaded under your own account.
