API Terms of Service

RoEx Tonn API Terms of Use and License Agreement

Effective Date: 28th February 2025

PLEASE READ THESE TERMS CAREFULLY. By clicking “Accept” or by accessing or otherwise using our Tonn Application Programming Interface (“Tonn API”), you (the “Customer”) agree to be bound by these RoEx Tonn API Terms of Use (“Terms”). If you do not agree with these Terms, please do not use our API.

1. Scope of Agreement

These Terms govern your access to and use of the Tonn API, including all associated software, documentation, and updates (collectively, the “Services”). This Agreement applies to your purchase of credits and any subsequent use of the API.

2. License Grant

Subject to your full compliance with these Terms, RoEx grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to:

Use the Tonn API solely for processing audio content (“Content”) submitted by you;
Make API calls (“API Calls”) to perform one or more of the available processes (Multitrack Mix, Master, Enhance, Audio Cleanup, or Mix Analysis) on submitted Content, and receive the resulting output (“Output”) in supported file formats; and
Display any data returned by the API solely within your own application or website, subject to the additional restrictions specified below under clause 4.

3. API Usage, Credits, and Fees

Users are responsible for managing their account using their dashboard on the Tonn API Portal at https://tonn-portal.roexaudio.com/.

Purchasing Credits:
Access to the Tonn API requires the purchase of prepaid credits via the dashboard, using a credit or debit card. All purchases are processed using Stripe, and are non-refundable. Credits must be used within 12 months of purchase before they expire.
Prepaid credits are sold to the Customer in bundles as listed below, at a base price of $0.10 per credit. The minimum number of credits that can be purchased in one transaction is 100:

Number of credits	Retail price	Discount on base price
100	$10.00	0%
500	$45.00	10%
1,000	$80.00	20%

Credit Balance:
Each API Call processes your Content using the requested audio process (“Process”). The balance of credits within your user account will be debited upon each successful completed API Call, as detailed in Exhibit A. Users are solely responsible for maintaining sufficient credits for API requests. RoEx is not liable for service interruptions due to insufficient credits or failed payments.
Credit Auto Top-Up:
Customers may enable Auto Top-Up in their account settings, allowing credits to be automatically replenished when the balance falls below a defined threshold. The linked payment method will be charged accordingly. RoEx is not responsible for enabling or disabling Auto Top-Up on User’s behalf, nor for any failure to process payments due to incorrect or outdated billing information. Users must manage their Auto Top-Up settings and payment details independently.
Usage:
You may use your credits for any combination of Multitrack Mix, Master, Enhance, Audio Cleanup, or Mix Analysis Processes. Additional credit charges may apply for optional features (such as processed stems download), as detailed on our pricing page at https://tonn-portal.roexaudio.com/pricing.

4. Restrictions on Use

You agree that you will not:

copy, rent, lease, sell, transfer, assign, sublicense, disassemble, reverse engineer or decompile (except to the limited extent expressly authorized by applicable statutory law), modify, create derivative works from, or alter any part of the API or Services;
Use any automated methods (e.g., scripts, bots, spiders) to access or interfere with the API;
Use the Services to develop or enhance a product or service that competes with RoEx;
Use the Services to train artificial intelligence, your own or a third-party algorithm, and/or any other kind of machine learning process;
Introduce or transmit any viruses, malware, or other harmful code; or
Otherwise engage in activity that interrupts the proper working of the API or use the API in any manner that violates any applicable law or infringes any third party’s rights.
