# Upload API

# Overview

The Turbo Upload Service supports payment for signed data-items to upload.ardrive.io using Turbo Credits. An API endpoint has been created to facilitate the payments. A signed data-item can be posted to upload.ardrive.io using the below schema.

Note: This service is still evolving and the information provided below may be out of date. You can view the most up to date information about the available endpoints here (opens new window), or view the raw json for that documentation here (opens new window).

# Endpoint

https://upload.ardrive.io/v1/tx

# Schema

# Headers

content-type*: "application/octet-stream"

accept*: string - media type, such as "application/json"

# Body

The body of your request should contain a signed data-item.

Data-items can be created and signed with the arbundles library, following the below example.

// Initiates the arbundles Arweave signer with your wallet
const signer = new ArweaveSigner(jwk);

// Sets the data you would like to use to create a data-item
const data = "Any value can Go here";

// Creates a data-item using your data and the Arweave Signer
const dataItem = createData(data, signer);

// Signs the data-item
await dataItem.sign(signer);

In this example, the variable dataItem is what should be sent in your api post request in order to finalize and pay for the upload using Turbo Credits. dataItem.sign() is a mutating method, so there is no need to create a separate variable to hold the results of signing the data-item.
