Terms of Service

1. Agreement to Terms

By creating an account, generating an API key, or otherwise accessing or using the Gramm Inc. 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 Inc. 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

Your use of the Service must comply with these Terms and with our separate Acceptable Use Policy, which we may update independently to reflect new operational guidance and applicable regulatory requirements.

In particular, 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, decompile, or attempt to extract the underlying models, algorithms, or training data.
• Systematically collect or store API outputs to build a competing forecast product or derivative model.
• Use API outputs as training data for machine learning models, neural networks, or statistical models without a separate Data License agreement.
• Redistribute API outputs to third parties as a standalone data feed or competing service. (Using forecasts to inform your own operational or trading decisions is permitted and encouraged.)
• Use robots, crawlers, scrapers, or automated tools to harvest, collect, or extract data from the Service beyond normal API usage.
• Store unaltered copies of API responses beyond 30 days unless required for audit or compliance purposes.
• 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 plan at any time by canceling your subscription.
• We may suspend access for overdue payments after 7 days’ written notice.

9. Indemnification

You agree to defend, indemnify, and hold harmless Gramm Inc., 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 Inc. 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.

Intended use and scope of fitness. The Service is designed for electricity demand forecasting on supported U.S. ISOs and RTOs at the resolutions and horizons documented in the API reference (hourly or sub-hourly resolution where available; horizons scoped by grid, plan, and validation status). The Service is not designed for and is not warranted for: (a) sub-minute or tick-level trading control loops, (b) safety-critical automatic dispatch or grid-control automation without independent backup feeds and human-in-the-loop approval, (c) markets, geographies, fuels, or commodities other than those documented as supported, or (d) any use case identified as out-of-scope in the Acceptable Use Policy. Customer is solely responsible for determining whether the Service is fit for Customer’s intended use.

11. Service Level

Gramm Inc. targets 99.9% monthly uptime for the forecast API on Developer, Team, and Growth plans. Uptime is calculated as the percentage of minutes the API returns non-error responses. Planned maintenance (with 48 hours’ notice) and upstream ISO/RTO data source outages are excluded. All self-serve plans (Free, Developer, Team, Growth) are provided on a commercially reasonable efforts basis without binding uptime guarantees or automatic service credits. Enterprise customers may negotiate binding SLA commitments, including uptime credits, as part of a commercial agreement.

12. Termination

• Either party may terminate with 30 days’ written notice.
• We may suspend or terminate immediately for Terms violations or non-payment.
• Your access to the Service terminates automatically if you institute, or knowingly assist in instituting, copyright or patent litigation against Gramm Inc. alleging that the Service or any forecast produced by the Service infringes your intellectual-property rights.
• On termination, your API keys are revoked and cached data is deleted within 30 days.
• Sections 6–10 and Section 15 (disclaimers, liability, indemnification, no-reliance, feedback) survive termination.

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.

15. Feedback

If you send Gramm Inc. suggestions, bug reports, accuracy observations, feature requests, or other feedback about the Service, you grant Gramm Inc. a perpetual, worldwide, irrevocable, royalty-free license to use, reproduce, and incorporate that feedback into the Service or any related products without obligation, attribution, or compensation. You retain no proprietary rights in the feedback itself; nothing in this section transfers ownership of any unrelated work product or pre-existing intellectual property you may reference when providing feedback.
