Developer Terms of Service

These Developer Terms govern your use of the Smarter Weather developer platform — including the public REST APIs, the public Model Context Protocol (MCP) servers, the meta MCP onboarding server, developer accounts, API keys, dashboards, and any accompanying SDKs or documentation (collectively, the “Developer Platform”). They supplement the main Smarter Weather Terms of Service and the Privacy Policy, which continue to apply. If there is a conflict between these Developer Terms and the main Terms with respect to the Developer Platform, these Developer Terms control.

By creating an API key, subscribing to a paid developer tier, or otherwise using the Developer Platform, you accept these Developer Terms. If you are acting on behalf of an organisation, you represent that you are authorised to bind that organisation.

Smarter Weather LLC grants you a non-exclusive, non-transferable licence to access and use the Developer Platform, subject to these Developer Terms, your selected tier, the Acceptable Use Policy, and applicable law.

• Free developer tier — for evaluation, prototyping, and low-volume non-commercial use. Subject to quota and rate limits. Provided on a best-effort, as-is basis without a binding service level.
• Paid developer tiers — a monthly subscription (with optional annual commitment) plus usage-based overage fees. Grants a commercial licence to use the Developer Platform within the scope of that tier and these Developer Terms. Current pricing is published at /developers/pricing.

The licence does not convey any ownership of the Developer Platform or the underlying data and may be suspended or terminated as described in these Developer Terms.

Paid developer tiers are billed through our payment processor, Stripe. By subscribing, you authorise us, via Stripe, to charge the payment method on file for all recurring subscription fees and any usage-based overage accrued during the billing period.

• Subscription fees are charged in advance at the beginning of each billing period (monthly by default, annually if selected).
• Usage-based overage is calculated from the metered API and MCP requests attributed to your API keys during the billing period and charged in arrears at the end of the period or on the next invoice, whichever comes first.
• Taxes are additional where applicable and are your responsibility unless we are legally required to collect them.
• Failed payment may result in the suspension of API keys and OAuth tokens until payment is resolved. Repeated failure may result in account termination.

• Auto-renewal — paid tier subscriptions renew automatically at the end of each billing period at the then-current price unless cancelled before the renewal date.
• Cancellation — you may cancel at any time from your developer dashboard. Cancellation takes effect at the end of the current billing period; you retain access to paid features until that date.
• Refunds — subscription fees are non-refundable except where required by law. Usage-based overage already accrued is non-refundable. In our sole discretion we may issue pro-rated credits or refunds for documented extended outages of the Developer Platform or for billing errors on our part.
• Material price changes — we will give at least 30 days' notice by email before increasing the subscription fee or published overage rates for your plan. If you do not accept the new pricing, you may cancel before it takes effect.

Your use of the Developer Platform is governed by our Acceptable Use Policy. In particular, you may not resell raw data, sublicense API or MCP access, use the Developer Platform to train machine-learning models without a separate written agreement, bypass rate limits or quotas, or deploy the Developer Platform in life-safety-critical contexts without independent verification and a documented fallback. We may suspend or terminate access for violations of the Acceptable Use Policy as described there.

• Our IP — the Developer Platform, the Smarter Weather name and marks, the proprietary blending algorithms and derived datasets, the dashboards, and the documentation are owned by Smarter Weather LLC and its licensors. No rights are granted other than the limited licence in these Developer Terms.
• Upstream data — weather observations, forecasts, and related products sourced from government agencies (including NOAA and the National Weather Service) and other third parties remain subject to their original licences and attribution requirements. You must preserve attribution in end-user-facing products as described in our Acknowledgements.
• Your content and applications — you retain all rights in the applications and content you build on the Developer Platform. You grant us a limited licence to process your requests, generate responses, and meter usage as needed to operate the Developer Platform.
• Feedback — if you send us ideas, suggestions, or feedback about the Developer Platform, you grant us a perpetual, irrevocable, royalty-free licence to use them without obligation.

We publish draft service-level targets at /developers/sla. Until a formal, binding Service Level Agreement is in place, those targets are informational; they do not create contractual remedies. We will notify paid customers in advance when binding SLAs become available and will attach them to these Developer Terms.

We strive to evolve the Developer Platform without breaking existing integrations. The policy below defines the minimum notice period for disruptive changes on stable, generally-available (GA) endpoints and tools. Beta or preview features are exempt and may change with shorter notice, which will be labelled in the documentation.

• Endpoint or tool removal — at least 6 months advance notice, with a deprecation banner in the response, an entry in the changelog, an email to the account owner, and (where available) a documented migration path.
• Breaking response-shape changes on a GA endpoint or tool (removing a field, changing a field's type, or changing required-parameter semantics) — at least 90 days advance notice, delivered the same way.
• Non-breaking additions — new fields, optional parameters, additional endpoints or tools, and bug fixes may be released at any time and are announced via the changelog.
• Security-driven changes — we may shorten these notice periods when required to address a security incident or legal obligation, with as much notice as is reasonably practicable under the circumstances.

You agree to defend, indemnify, and hold harmless Smarter Weather LLC, its officers, employees, and agents from and against any third-party claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Developer Platform; (b) your violation of these Developer Terms or the Acceptable Use Policy; (c) your applications, products, or services built on the Developer Platform, including any claims that they caused harm to end users; or (d) your violation of any third-party right, including any intellectual-property or privacy right.

We will indemnify and defend you against any third-party claim that the Developer Platform, as provided by us and used in accordance with these Developer Terms, infringes that third-party's U.S. copyright or trademark. This is our sole liability and your sole remedy for infringement claims related to the Developer Platform. It does not apply to claims arising from your combination of the Developer Platform with other systems, your modification of responses, or your use of the Developer Platform outside the scope of these Developer Terms.

The Developer Platform is provided “as is” and “as available.” Weather data is inherently uncertain and may be incomplete, delayed, or wrong. See our Disclaimer for important context.

To the maximum extent permitted by law, the aggregate liability of Smarter Weather LLC to you for any and all claims arising out of or related to the Developer Platform or these Developer Terms is limited to the greater of (a) the fees you paid us for the Developer Platform in the twelve months immediately preceding the event giving rise to the claim, or (b) one hundred U.S. dollars (US$100). In no event will we be liable for indirect, incidental, consequential, special, or exemplary damages, or for lost profits, lost revenue, lost data, or loss of goodwill, even if we have been advised of the possibility of such damages.

Our processing of personal data for developer accounts is described in our Privacy Policy. A current list of subprocessors is maintained at /developers/subprocessors.

A Data Processing Addendum (DPA) is available on request for customers who need one for internal due diligence or to satisfy GDPR, UK GDPR, or CCPA obligations. To request a DPA, email alex@smarterweather.com or use the contact form with the subject “DPA request.”

• By you — you may stop using the Developer Platform at any time, cancel your paid subscription from the dashboard, and revoke your API keys.
• By us — we may suspend or terminate your access, revoke API keys, or refuse to issue new ones if: you fail to pay fees when due; you violate these Developer Terms or the Acceptable Use Policy; your use threatens the security, integrity, or availability of the Developer Platform; or we are required to do so by law.
• Effect of termination — on termination, your access to the Developer Platform ends and outstanding fees become immediately due. Sections that by their nature should survive termination (including intellectual-property, indemnification, limitation of liability, and governing-law provisions) will survive.

We may update these Developer Terms from time to time. Material changes will be announced by email to the account owner and posted here at least 30 days before taking effect, except where a shorter notice period is required by law or needed to respond to a security or legal event. Continued use of the Developer Platform after the effective date constitutes acceptance of the updated terms.

These Developer Terms are governed by the laws of the State of Illinois, USA, without regard to conflict-of-law principles. The state and federal courts located in Cook County, Illinois have exclusive jurisdiction over any dispute arising out of or related to these Developer Terms, and you consent to personal jurisdiction and venue there.
