Terms of Service

Last updated: October 28, 2026

1. Acceptance of Terms

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

2. Description of Service

Addrex provides address validation and available location intelligence through its website, console and APIs. Results may include standardized components, postal evidence and match confidence. Physical location and other intelligence are shown only where supported by available evidence.

Addrex does not claim USPS DPV or CASS certification. A postal range match, physical location match and delivery confirmation are different forms of evidence. Results do not guarantee mail delivery or establish that a nearby hazard affected a property.

3. Account Registration

The website allows one initial address lookup without an account. Continuing with another address or using account workflows requires registration or sign-in. Depending on how you use Addrex, you may access features through a web dashboard (e.g., uploading spreadsheets) or through an API key for programmatic access. You are responsible for maintaining the confidentiality of your login credentials and API keys, and for all activity under your account. You agree to notify us immediately of any unauthorized use.

4. Acceptable Use

You agree not to:

  • Use the Service for any unlawful purpose
  • Attempt to reverse-engineer, decompile, or extract our reference dataset
  • Exceed rate limits or circumvent usage restrictions
  • Resell or redistribute the Service without authorization
  • Use the Service to build a competing product using our data
  • Use Addrex output to send unsolicited bulk mail or email in violation of CAN-SPAM, TCPA, or equivalent regulations
  • You agree to indemnify Addrex against any claims arising from your use of validated addresses for unlawful purposes

5. Demo and Trial Use

  • The free demo is provided to evaluate the Addrex platform. It is not intended as a production service.
  • The public experience permits one first-address lookup and available intelligence for that same address. A second new-address submission requires account access.
  • Automated, scripted, or programmatic access to the demo without authorization is prohibited.
  • We reserve the right to suspend access for any user or IP address that abuses the demo system, including but not limited to automated scraping, bulk extraction of results, or circumvention of export controls.

6. Anti-Scraping

  • You may not use bots, scrapers, browser automation, or any automated tool to extract data from the Addrex platform without written authorization.
  • Violation may result in immediate suspension and permanent ban from the service.

7. Pricing and Billing

  • Plan details, features, and usage limits are described on our Pricing page at addrex.dev/pricing and may be updated from time to time.
  • Paid plans are billed monthly via Stripe.
  • Cancel anytime. Access continues through the current billing period.
  • No refunds are provided for partial months.
  • We may change pricing with 30 days notice to active subscribers.

8. Data Handling

Retention varies by workflow. Account uploads, results, usage records and feedback may remain stored beyond a request. Contact us for data access or deletion requests. See our Privacy Policy for full details.

9. Service Availability

We strive for high availability but do not guarantee uninterrupted access. Any service-level commitment must be stated in a separate written agreement. We may perform scheduled maintenance with reasonable notice.

10. Intellectual Property

The Service, including our reference dataset, algorithms, and documentation, is owned by Addrex and protected by applicable intellectual property laws. Your use of the Service does not grant you ownership of any content, data, or materials you access.

11. Limitation of Liability

To the maximum extent permitted by law, Addrex shall not be liable for any indirect, incidental, special, consequential, or punitive damages resulting from your use of the Service. Our total liability shall not exceed the amounts paid by you in the 12 months preceding the claim.

12. Termination

Either party may terminate this agreement at any time. We may suspend or terminate your access if you violate these terms. Upon termination, your right to use the Service ceases immediately.

13. Changes to Terms

We may update these terms from time to time. We will notify you of material changes via email or through the Service. Continued use after changes constitutes acceptance of the updated terms.
