Terms of service
Last updated: April 30, 2026.
Agreement
By creating an account, calling the API, or using related websites, you agree to these terms and our Privacy policy.
The service
We provide address validation, geocoding, and related APIs on an “as available” basis. Outputs depend on reference data and algorithms; they are not guaranteed error-free. You are responsible for your use in compliance with law (including marketing, credit, and data-protection rules in your sector).
API keys & acceptable use
API keys are confidential. You must not resell or share keys in ways that breach your plan. You must not abuse the service (e.g. circumvent rate limits, attack infrastructure, or use the API to build a substantially similar competing database by systematic extraction — see Anti-scraping & bulk extraction below).
Anti-scraping & bulk extraction
The Acuris reference databases are our proprietary assets and the Acuris API is licensed for transactional, end-user-driven lookups only. You must not systematically query, scrape, mirror, cache beyond the term of your subscription, or otherwise extract Acuris content with the intent of reconstructing all or a material portion of the underlying reference data — whether for internal redistribution, resale, public dataset publication, or training of third-party models or geocoding services. "Systematic" extraction includes, without limitation: bulk enumeration of postcodes, streets, ranges of house numbers, administrative areas, or coordinate grids; iterating known address dictionaries against the API to mirror the underlying database; reverse-geocoding sweeps over geographic tiles; and any access pattern materially inconsistent with end-user request volume on a Customer-facing application.
To detect and deter unauthorized extraction, Acuris and/or its data partners may include a limited number of seed records — distinctive, traceable entries embedded in the reference data — and may monitor third-party services, public datasets, and downstream offerings for the appearance of these records. Resale, public exposure, or model training using any seed record found outside an authorized customer's Permitted Use is conclusive evidence of breach and may result in immediate suspension, termination, charge-back of fees waived under prior arrangements, and legal action including injunctive relief and damages. Seed records do not affect normal end-user lookups; they exist solely as a tripwire for unauthorized bulk use.
If you require a bulk data licence for ingestion into your own database — for offline geocoding, batch enrichment, or training of AI models — contact sales@acuris-geo.com. Bulk extraction outside of such a licence is a material breach of these terms and we reserve all rights, including under copyright, database-rights legislation (Directive 96/9/EC and equivalents), unfair-competition, and contract law.
Third-party data licences (UK / Royal Mail PAF®)
Some Acuris services incorporate data licensed from third parties. In particular, Acuris's UK address validation, UK postcode lookup and related UK services are built using the Royal Mail Postcode Address File (PAF®), licensed to Acuris GmbH as a Royal Mail PAF® Solutions Provider.
By using any Acuris service that returns UK address data, you agree to be bound by the Royal Mail PAF® End User Terms as an End User, and you must ensure your own users comply with them. In summary, those terms require that you do not copy PAF® data except as permitted, do not extract or supply PAF® data to third parties outside the permitted uses, do not re-sell or sub-licence the data, retain Royal Mail's ownership notices, and cease use of and destroy PAF® data if your right to use it ends. Royal Mail does not warrant the accuracy or completeness of PAF® data. Royal Mail may enforce these terms against you and Acuris may suspend or terminate your access to UK data if you breach them. UK UPRN identifiers are derived from Ordnance Survey OS Open UPRN under the Open Government Licence v3.0. Required acknowledgements are set out on our Attributions page.
Pricing & service-limit changes
Usage is metered against the monthly quotas described on Pricing. We may change pricing or service limits. For paid plans, we will provide at least thirty (30) days’ notice via email before changes take effect. Free-tier limits may change at any time.
Disclaimer & liability
To the extent permitted by law, we disclaim warranties of merchantability, fitness for a particular purpose, and non-infringement. To the extent permitted by law, our total liability arising out of or relating to these terms shall not exceed the fees paid by you to us in the twelve (12) months preceding the event giving rise to the claim. We are not liable for indirect, consequential, special, or punitive damages.
Termination
We may suspend or terminate access for breach, risk, or non-payment. You may stop using the service at any time.
Governing law
These terms are governed by the laws of Germany. Disputes shall be resolved in the competent courts of Frankfurt, Germany. The parties waive any right to a jury trial.
