# OFT API Overview

> Technical reference for OFT API Overview. Complete API documentation, function signatures, and implementation details for LayerZero V2. Architecture and impl...

The OFT API is a simple way to discover LayerZero OFTs across all chains within the LayerZero [omnichain mesh](/v2/concepts/protocol/mesh-network).

You can use the API for free to discover all available OFTs, or get an API key to generate transaction calldata for any network to call the send function on any of the OFTs with given parameters.

## List Route API

An endpoint that provides structured metadata and availability information about supported OFTs across chains.

#### Use for:

* Viewing OFTs as well as their availability on different chains
* Looking up contract addresses
* Getting configuration details

You can try out the List Route API [here](./oft-examples).

## Direct Transfer API

An endpoint that provides anyone with a simple, efficient way to offer native OFT transfers directly within their interfaces.

**Requires an API key**

Request an [API key](https://forms.monday.com/forms/c64c278b03d2b40a24e305943a743527?r=use1).

#### Use for:

* Completing direct debit and credit transfers of OFTs across supported chains

You can explore the List Route API endpoints [here](./oft-examples).
