1. Agreement to Terms

By accessing or using the Road511 API, website, or any related services (collectively, the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not use the Service.

Road511 is a sole proprietorship owned and operated by Roman Kotenko ("we", "us", "our").

2. Description of Service

Road511 provides a REST API that aggregates and normalizes publicly available traffic data from North American 511 traffic systems and related government data sources. The Service includes API access, documentation, developer portal, and related tools.

3. Account Registration

To use the API, you must create an account and obtain an API key. You agree to:

• Provide accurate and complete registration information
• Maintain the security of your account credentials and API keys
• Promptly notify us of any unauthorized use of your account
• Accept responsibility for all activity under your account

4. Acceptable Use

You agree not to:

• Share, publish, or redistribute your API keys
• Exceed the rate limits or quotas of your subscription plan
• Use the Service for any unlawful purpose
• Attempt to reverse-engineer, decompile, or derive source code from the Service
• Resell, sublicense, or redistribute raw API responses as a competing data service
• Use automated means to scrape or bulk-download data beyond normal API usage
• Interfere with or disrupt the Service or its infrastructure
• Misrepresent Road511 data as your own original data source

5. Subscription Plans and Payment

The Service is offered under tiered subscription plans. Details of each plan, including pricing, rate limits, and quotas, are listed on our website and may change with prior notice.

• Subscriptions are billed monthly in advance
• Payment is processed by Paddle.com (our merchant of record), which handles all billing, taxes, and invoicing
• You agree to Paddle's terms of service in addition to these Terms
• Failure to pay may result in suspension or termination of your account

6. Refund Policy

All payments are non-refundable. You may cancel your subscription at any time, and your access will continue until the end of the current billing period. No pro-rata refunds are provided for partial months. See our Refund Policy for full details.

7. Data and Attribution

The traffic data provided through the Service is sourced from publicly available government 511 systems and data services. Road511 normalizes and aggregates this data but does not own the underlying source data.

• We do not guarantee the accuracy, completeness, or timeliness of the data
• You should not rely on this data for safety-critical or life-safety decisions without independent verification
• You are responsible for compliance with any attribution or usage requirements of the original data sources

8. Service Availability

We strive to provide reliable, continuous service but do not guarantee 100% uptime. The Service may be temporarily unavailable due to:

• Scheduled maintenance (with reasonable advance notice when possible)
• Upstream data source outages beyond our control
• Force majeure events
• Infrastructure failures

9. Intellectual Property

The Service, including its API design, documentation, code, and branding, is the intellectual property of Roman Kotenko. You are granted a limited, non-exclusive, non-transferable license to use the Service in accordance with your subscription plan.

10. Limitation of Liability

To the maximum extent permitted by law, Road511 and its owner shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or business opportunities, arising from your use of the Service.

Our total liability for any claim arising from or related to the Service shall not exceed the amount you paid us in the 12 months preceding the claim.

11. Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

12. Termination

We may suspend or terminate your access to the Service at any time for violation of these Terms, non-payment, or any other reason at our discretion. Upon termination:

• Your API keys will be revoked
• You must cease all use of the Service
• No refunds will be issued for the remaining billing period

13. Changes to Terms

We may modify these Terms at any time. Material changes will be communicated via email or a notice on the website. Continued use of the Service after changes constitutes acceptance of the updated Terms.

14. Governing Law

These Terms are governed by and construed in accordance with applicable law. Any disputes shall be resolved through good-faith negotiation first, and if necessary, through binding arbitration.
