# Introduction

> Endpoint specs for stablecoin movement — accept, transfer, redeem, and webhooks — across Tempo, Solana, Base, and Arc.

## Overview

The REM API gives institutional teams programmatic access to stablecoin movement across the supported networks:

* **Stablecoins** — `accept`, `transfer`, `redeem` across Tempo, Solana, Base, and Arc
* **Webhooks** — signed events on every accept / transfer / redeem

Each endpoint enforces the same compliance pipeline (KYC, KYB, KYT, Travel Rule, TIP-403) before settlement.

<Note>
  Tokenisation, Compliance Engine, and Settlement Zones are delivered as designed deployments rather than self-serve APIs. See the respective module pages and [Custom Solutions](/source/intro/services) to scope an engagement.

## Authentication

All endpoints require a dynamic API key. Include it in the `Authorization` header on every request:

```bash theme={null}
Authorization: Bearer <your_api_key>
```

API keys are scoped per environment and per module. Generate and rotate keys in the [REM Dashboard](https://rem.money).

## Environments

| Environment    | Base URL                       |
| :------------- | :----------------------------- |
| **Devnet**     | `https://devnet.api.rem.money` |
| **Production** | `https://api.rem.money`        |

<Note>
  Test all integration logic in **Devnet** using the simulation endpoints before moving to production.
</Note>

## Webhooks

Every accept, transfer, and redeem event fires a signed (HMAC-SHA256) webhook. Configure endpoints in the dashboard; verify signatures with `@rem-money/sdk`.

## SDKs

| Language   | Package                       |
| :--------- | :---------------------------- |
| TypeScript | `@rem-money/sdk`              |
| Python     | `rem-money`                   |
| Go         | `github.com/rem-money/sdk-go` |
| REST       | direct HTTP                   |

## Custom integrations

Need an endpoint, an SDK, or an integration that isn't here yet? REM's team builds bespoke API surfaces for institutional clients — including private endpoints, custom auth flows, and dedicated SLAs.
