API Terms of Service

1. INTRODUCTION AND SCOPE

These API Terms of Service ("API Terms") govern your access to and use of the Blockunity Business API service ("API Service" or "Service") operated by HYVI LDA ("we", "us", "our", "Blockunity"). The API Service is accessible through the following domains:

• business.blockunity.io - Primary Business dashboard and API portal
• hyvicore.blockunity.io - API endpoint domain
• hyvicore.com - Alternative API endpoint domain
• hyvicore.io - Alternative API endpoint domain

By creating an account, generating an API key, or making any API request, you ("Client", "you") confirm that you have read, understood, and agree to be bound by these API Terms, our General Terms of Use, Privacy Policy, and API Privacy Addendum.

These API Terms supplement and do not replace our General Terms of Use. In case of conflict, these API Terms shall prevail with respect to the API Service.

We reserve the right to modify these API Terms at any time. The updated date at the top of this page indicates when the terms were last revised. Continued use of the API Service after modifications constitutes your acceptance of the updated terms.

2. SERVICE DESCRIPTION

The Blockunity Business API provides programmatic access to cryptocurrency and financial market data, analytics, indicators, scoring, and related computational tools via RESTful API endpoints. The Service is designed for integration into your applications, internal tools, or research workflows.

The API Service is an informational and analytical tool only. It does not provide investment, financial, or trading advice. It does not facilitate the purchase, sale, or exchange of any financial instruments. All data is provided on an "as-is" basis. You are solely responsible for any decisions made based on data obtained through the Service.

3. SUBSCRIPTION PLANS AND BILLING

3.1 Available Plans

The API Service offers three subscription tiers:

• Starter - Designed for personal use, individual research, and evaluation purposes only. Not suitable for commercial or production use.
• Professional - Designed for internal business use with higher rate limits and additional features.
• Custom - A fully bespoke plan tailored to your specific needs, negotiated directly with our team.

Plan details, pricing, features, and credit allocations are available at business.blockunity.io.

3.2 Billing

• Subscriptions are billed on a monthly or annual basis, with no long-term commitment. You may cancel at any time.
• Payments are processed through Stripe. You must provide valid and current payment information.
• If a payment fails, we may retry processing in the following days. Access to paid features will be suspended until payment is successfully processed.
• Subscriptions renew automatically at the end of each billing cycle unless cancelled prior to the renewal date.

3.3 Free Trial Credits

Upon account creation, complimentary credits are provided free of charge to allow you to test and evaluate the API Service. These trial credits are subject to the same usage restrictions as paid credits. Trial credits may expire and cannot be transferred or exchanged for monetary value.

3.4 Credits and Overage

• Each API request consumes a number of credits depending on the endpoint and complexity of the request.
• Credits included in your plan are allocated per billing cycle and do not roll over to the next period (except purchased or bonus credits).
• If overage billing is enabled on your plan, additional credits consumed beyond your allocation will be billed at the per-credit overage rate specified in your plan.

3.5 Refund Policy

Refund requests must be submitted within 14 days of subscribing by contacting [email protected]. Refunds are granted at the sole discretion of Blockunity and in compliance with applicable European consumer protection laws. Refunds may be denied in cases of significant API usage, abuse, or violation of these API Terms.

4. DATA LICENSE AND USAGE RESTRICTIONS
