Terms of Service

1. Acceptance of Terms

By accessing or using the Hyperlight API, WebSocket streams, website, documentation, data lake exports, or any related services (collectively, the “Service”), you (“Customer”, “you”) agree to be bound by these Terms of Service (“Terms”). If you are entering into these Terms on behalf of a company or other legal entity, you represent that you have the authority to bind such entity. If you do not agree to these Terms, you must not access or use the Service.

2. Service Description

Hyperlight provides enhanced programmatic access to Lighter market data, including batch account queries, enriched WebSocket streams, historical orderbook snapshots, OHLCV candles, funding rate history, liquidation data, and Parquet data lake exports (collectively, the “Data”). The Service augments and processes data sourced from the Lighter protocol and is delivered via authenticated REST APIs and WebSocket connections.

3. License Grant

Subject to your compliance with these Terms and timely payment of all applicable fees, Hyperlight grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service and Data solely for your own internal business purposes. This license does not convey ownership of any Data or any intellectual property rights therein.

4. Data Use Restrictions

The following restrictions are material conditions of the license granted in Section 3. Violation of any restriction constitutes a material breach and grounds for immediate termination.

4.1 Prohibited Uses

Customer shall not:

• Redistribute, resell, sublicense, publicly display, broadcast, or otherwise make the Data available to any third party, whether in raw, processed, aggregated, or reformatted form.
• Create competing or substitute products: Use the Data to create, develop, operate, market, or offer any product, service, platform, API, data feed, or information service that competes with, replicates the functionality of, or could reasonably serve as a substitute for the Service or any Hyperlight offering (the “Substitutability Test”). If a reasonable person could use Customer’s product in place of a Hyperlight subscription, such use is prohibited.
• Systematically download or cache: Download, store, archive, or cache Data for the purpose of building a database, data warehouse, data repository, or any persistent data store intended to reduce or eliminate dependency on the Service.
• Generate third-party trading signals: Use the Data to generate automated or semi-automated trading signals, alerts, or recommendations for distribution to third parties. Use for Customer’s own proprietary trading is permitted.
• Share credentials across organizations: Share, pool, or otherwise make API keys, access tokens, or login credentials available across distinct legal entities, subsidiaries, affiliated organizations, or economic units under common control.
• Reverse engineer or decompile: Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, data models, or trade secrets underlying the Service.
• Circumvent access controls: Bypass, disable, or circumvent rate limits, authentication mechanisms, IP restrictions, tier enforcement, or any other security or access control measure.

4.2 Derived Data Restrictions

Any data derived from, based upon, computed using, or created with reference to the Data — including but not limited to aggregations, transformations, statistical analyses, indexes, signals, blended datasets, or reformatted versions (collectively, “Derived Data”) — shall remain subject to all restrictions set forth in these Terms. Customer shall not distribute, publish, or make Derived Data available externally in any form that could serve as a substitute for, or diminish the commercial value of, the original Data or the Service. Notwithstanding the foregoing, Customer may include insubstantial amounts of Derived Data in internal reports and research documents that support Customer’s primary business activities, provided such use does not constitute an independent data product.

4.3 AI and Machine Learning Prohibition

Customer shall not use the Data to train, fine-tune, validate, benchmark, distill, or otherwise develop machine learning models, artificial intelligence systems, large language models, or foundation models — whether for internal use, commercial distribution, or open-source release — without prior written consent from Hyperlight. Any such consent, if granted, may be subject to additional licensing fees and restrictions.

4.4 Non-Display Use

Use of the Data in automated, algorithmic, or non-display applications (including backend processing, automated decision-making, quantitative analysis engines, and systematic trading systems) is permitted only on Starter tier or above. Non-display usage at scale (exceeding 5 million requests per month) may require an Enterprise licensing agreement. Hyperlight reserves the right to reclassify usage as non-display based on observed access patterns.

4.5 Single-Use License

Each subscription is licensed to a single legal entity. Use across multiple legal entities, subsidiaries, divisions, or affiliated organizations requires separate subscriptions or an Enterprise agreement. Pooling API quotas, sharing access tokens, or aggregating Data across multiple subscriptions for the benefit of a single entity is prohibited.

5. Acceptable Use

Customer agrees to:

• Comply with all applicable rate limits, batch size restrictions, and concurrency caps associated with Customer’s subscription tier.
• Not engage in abusive, excessive, or disruptive usage patterns that degrade the Service for other customers.
• Not use automated scripts, bots, or crawlers to access the Service beyond the capabilities of the provided API, except as explicitly authorized.
• Not intentionally submit malformed requests, exploit vulnerabilities, or attempt denial-of-service attacks against the Service.
• Comply with all applicable laws and regulations in connection with use of the Service.

6. Account Registration and Security

You must provide accurate and complete registration information. You are responsible for maintaining the confidentiality of your account credentials, API keys, and access tokens. You are solely responsible for all activities that occur under your account. You must notify Hyperlight immediately at support@hyperlightapi.xyz of any unauthorized use of your account or any other security breach. Hyperlight shall not be liable for any loss arising from unauthorized use of your credentials.

7. Billing and Payment

• Subscriptions: Paid plans are billed monthly in advance via Stripe. You authorize Hyperlight to charge your designated payment method for recurring subscription fees.
• Overage charges: API usage exceeding your tier’s included monthly request quota is billed as metered overage at the rate specified for your plan. Overage charges are calculated and reported hourly.
• Cancellation: You may cancel your subscription at any time via the Stripe Customer Portal accessible from your dashboard. Cancellation takes effect at the end of the current billing period. No prorated refunds are provided for partial billing periods.
• Price changes: Hyperlight may modify pricing with at least 30 days’ written notice. Continued use of the Service after the effective date constitutes acceptance of the new pricing.
• Taxes: All fees are exclusive of applicable taxes. Customer is responsible for all taxes associated with use of the Service.

8. Intellectual Property

The Service, including all software, APIs, documentation, data processing algorithms, trade secrets, trademarks, and the Data itself, are and shall remain the exclusive property of Hyperlight and its licensors. No rights are granted to Customer except the limited license expressly set forth in Section 3. Customer acquires no ownership interest in the Data by virtue of accessing or downloading it through the Service. All rights not expressly granted herein are reserved by Hyperlight.

9. Monitoring and Enforcement

Hyperlight reserves the right to:

• Monitor API usage patterns, access logs, and Data consumption to verify compliance with these Terms.
• Audit Customer’s use of Data upon reasonable notice to ensure compliance with the data use restrictions in Section 4.
• Throttle, rate-limit, or temporarily suspend access to the Service for suspected violations or unusual usage patterns pending investigation.
• Immediately terminate or suspend access without notice for material breach of these Terms, including any violation of the data use restrictions in Section 4.
• Pursue all available legal remedies, including injunctive relief and monetary damages, for unauthorized redistribution, competitive use, or other material violations of these Terms.

10. Limitation of Liability

• IN NO EVENT SHALL HYPERLIGHT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS, DATA, GOODWILL, OR TRADING LOSSES, REGARDLESS OF THE THEORY OF LIABILITY.

11. Indemnification

Customer shall indemnify, defend, and hold harmless Hyperlight, its officers, directors, employees, and agents from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or relating to: (a) Customer’s use of the Service or Data in violation of these Terms; (b) Customer’s unauthorized redistribution of Data or Derived Data; (c) any third-party claims arising from Customer’s products or services that incorporate the Data; or (d) Customer’s violation of applicable law.

12. Termination

• Either party may terminate these Terms at any time. Customer may terminate by canceling the subscription through the Stripe Customer Portal.
• Hyperlight may terminate or suspend access immediately, without prior notice, for material breach of these Terms — including any violation of Section 4 (Data Use Restrictions).
• Upon termination, Customer’s license to access the Service and Data is immediately revoked. Customer must cease all use of the Data and permanently destroy all copies of Data and Derived Data in Customer’s possession or control within thirty (30) days.
• Sections 4 (Data Use Restrictions), 8 (Intellectual Property), 10 (Limitation of Liability), 11 (Indemnification), and 13 (Governing Law) shall survive termination.

13. Governing Law and Dispute Resolution

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of laws provisions. Any dispute arising out of or relating to these Terms shall be resolved by binding arbitration administered by the American Arbitration Association in accordance with its Commercial Arbitration Rules. The arbitration shall take place in Delaware, and the arbitrator’s award shall be final and binding. Notwithstanding the foregoing, Hyperlight may seek injunctive or equitable relief in any court of competent jurisdiction to protect its intellectual property rights or enforce the data use restrictions in Section 4.

14. General Provisions

• Entire Agreement: These Terms, together with any applicable Enterprise agreement, constitute the entire agreement between Customer and Hyperlight regarding the Service and supersede all prior agreements and understandings.
