# Environments and Base URLs

> Production and Sandbox base URLs for the eBRC API. Build against the sandbox where nothing is legally binding, then switch to production for real filings.

The eBRC API runs in two environments. Your API key is issued for one of them, and the host you call decides where your requests go.

| Environment    | Base URL                                   | What it is for                                                          |
| -------------- | ------------------------------------------ | ----------------------------------------------------------------------- |
| **Production** | `https://ebrcapi.eximfiles.io/api/v1`      | Live filings. Certificates generated here are real and legally binding. |
| **Sandbox**    | `https://ebrcapi.dev.eximfiles.com/api/v1` | Building and testing. Nothing filed here is legally binding.            |

<Note>
  Generation endpoints are available in Production and Sandbox. In Production, a generation request is typically acknowledged within about 2 hours.
</Note>

## How environments behave

* API keys are issued per environment. A sandbox key does not work against the production host, and the other way round.
* Build against the sandbox first. Nothing is legally binding until you move to production keys and the production host.
* Every generation request records the environment it was filed in, so a test run is never mistaken for a live filing.

## Data extraction hosts

The [Data extraction APIs](/api-reference/extraction/introduction) run on a separate Tradelens host with their own API key:

| Environment    | Base URL                                            |
| -------------- | --------------------------------------------------- |
| **Production** | `https://tradelens-apis.eximfiles.io/platform`      |
| **Sandbox**    | `https://tradelens-apis.dev.eximfiles.com/platform` |
