Last updated: March 30, 2026

1. Agreement to Terms

By creating an account, generating an API key, or otherwise accessing or using the Gramm AI API and related services (the “Service”), you (“Customer” or “you”) agree to be bound by these Terms of Service (“Terms”). If you are accepting on behalf of an organization, you represent that you have authority to bind that entity. If you do not agree, do not use the Service.

2. Service Description

Gramm AI provides an API for electricity demand forecasting, grid data, and related analytics. Forecast data may be derived from proprietary models, third-party sources, government agencies, and independent data providers. No guarantee is given regarding the accuracy, availability, completeness, or suitability of any data or forecast.

3. Accounts & API Keys

  • You must provide accurate account information and keep it current.
  • You are responsible for all activity under your account and API keys.
  • Keep API keys confidential. Notify us immediately if you suspect unauthorized use.
  • We may suspend or terminate accounts that violate these Terms.

4. Acceptable Use

You agree not to:

  • Exceed your plan’s rate limits or circumvent access controls.
  • Redistribute, resell, or sublicense raw API data without written permission.
  • Reverse-engineer or attempt to extract the underlying models.
  • Use the Service for any unlawful purpose or in violation of export controls.
  • Interfere with or disrupt the integrity or performance of the Service.

5. Billing & Subscription

  • Paid plans are billed monthly via Stripe. Fees are non-refundable except as required by law.
  • We may change pricing with 30 days’ notice. Continued use after the change constitutes acceptance.
  • Downgrade to the free tier at any time by canceling your subscription.
  • We may suspend access for overdue payments after 7 days’ written notice.

6. Forecast Accuracy Disclaimer

GRAMM AI MAKES NO EXPRESS OR IMPLIED WARRANTIES, GUARANTEES, OR AFFIRMATIONS THAT FORECASTED ENERGY DEMAND DATA, GRID CONDITIONS, OR RELATED PREDICTIONS WILL OCCUR AS STATED. GRAMM AI SHALL HAVE NO RESPONSIBILITY OR LIABILITY WHATSOEVER FOR ANY INCONSISTENCY, INACCURACY, OR OMISSION IN FORECASTED OR PREDICTED DATA.

ACCURACY METRICS PUBLISHED ON THE GRAMM AI WEBSITE (SUCH AS MAPE, RMSE, OR IMPROVEMENT PERCENTAGES) DESCRIBE HISTORICAL MODEL PERFORMANCE ON BENCHMARK DATASETS AND DO NOT CONSTITUTE A GUARANTEE OF FUTURE PERFORMANCE ON ANY SPECIFIC GRID, TIMEFRAME, OR USE CASE.

THE SERVICE IS NOT A SUBSTITUTE FOR PROFESSIONAL JUDGMENT. CUSTOMER IS SOLELY RESPONSIBLE FOR ALL OPERATIONAL, FINANCIAL, AND TRADING DECISIONS MADE BASED ON DATA OR FORECASTS PROVIDED BY THE SERVICE. GRAMM AI OFFERS NO FINANCIAL, INVESTMENT, OR TRADING ADVICE.

7. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, COMPLETENESS, RELIABILITY, NON-INFRINGEMENT, TITLE, SECURITY, COMPATIBILITY, OR UNINTERRUPTED SERVICE.

GRAMM AI DOES NOT WARRANT THAT THE SERVICE OR DATA WILL BE FREE FROM BUGS, DEFECTS, OR ERRORS, OR THAT THE SERVICE WILL BE ACCESSIBLE WITHOUT INTERRUPTION. DATA MAY BE DERIVED FROM THIRD-PARTY SOURCES AND NO GUARANTEE IS GIVEN REGARDING THE ACCURACY OR AVAILABILITY OF THIRD-PARTY DATA.

8. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, STATUTORY, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF REVENUE, PROFITS, GOODWILL, DATA, BUSINESS OPPORTUNITIES, ANTICIPATED SAVINGS, OR TRADING LOSSES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

GRAMM AI’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE TOTAL FEES PAID BY CUSTOMER IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED DOLLARS ($100 USD).

THE FOREGOING LIMITATIONS APPLY REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR OTHERWISE) AND EVEN IF A LIMITED REMEDY SET FORTH HEREIN IS FOUND TO HAVE FAILED OF ITS ESSENTIAL PURPOSE.

9. Indemnification

You agree to defend, indemnify, and hold harmless Gramm AI, its officers, directors, employees, and agents from any third-party claims, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of: (a) your use of the Service, (b) any application or product you build using the Service, (c) any operational, financial, or trading decisions made based on data or forecasts provided by the Service, or (d) your violation of these Terms.

Gramm AI will indemnify Customer against third-party claims alleging that the Service infringes a valid U.S. patent or copyright, provided Customer gives prompt written notice, grants sole control of the defense, and provides reasonable cooperation.

10. No Reliance; Independent Verification

Customer acknowledges that forecast data is inherently uncertain and agrees not to use the Service as the sole basis for any decision that could result in financial loss, bodily injury, or property damage. Customer agrees to maintain independent verification and backup systems appropriate to its use case.

Customer assumes the entire risk related to its use of the Service and any data or forecasts obtained through the Service.

11. Service Level

Standard and Enterprise plans include a 99.9% monthly uptime target. Uptime is calculated as the percentage of minutes the API returns non-error responses. Planned maintenance (with 24 hours’ notice) is excluded. In the event of SLA breach, Customer’s sole remedy is a service credit equal to 10% of the monthly fee for each 0.1% below the target, up to 30% of that month’s fees. Credits must be requested within 30 days.

12. Termination

  • Either party may terminate with 30 days’ written notice.
  • We may suspend or terminate immediately for Terms violations or non-payment.
  • On termination, your API keys are revoked and cached data is deleted within 30 days.
  • Sections 6–10 (disclaimers, liability, indemnification, no-reliance) survive termination.

13. Dispute Resolution

These Terms are governed by the laws of the State of California, without regard to conflict of laws principles.

ANY DISPUTE ARISING OUT OF OR RELATING TO THESE TERMS SHALL BE RESOLVED BY BINDING ARBITRATION ADMINISTERED BY JAMS UNDER ITS STREAMLINED ARBITRATION RULES, BEFORE A SINGLE ARBITRATOR IN SANTA CLARA COUNTY, CALIFORNIA. THE ARBITRATOR’S AWARD SHALL BE FINAL AND ENFORCEABLE IN ANY COURT OF COMPETENT JURISDICTION.

YOU AGREE TO RESOLVE DISPUTES ON AN INDIVIDUAL BASIS. YOU WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION, CLASS ARBITRATION, OR REPRESENTATIVE PROCEEDING.

Exception: either party may seek injunctive relief in a court of competent jurisdiction to prevent irreparable harm. Claims must be brought within one (1) year after the cause of action arose.

14. Changes to These Terms

We may update these Terms from time to time. Material changes will be communicated via email and an in-dashboard notice at least 30 days before they take effect. Continued access to the Service after the effective date constitutes acceptance. If you do not agree to updated Terms, you must stop using the Service before the effective date.
