Acceptable Use Policy
Last updated: March 2026
This Acceptable Use Policy (“AUP”) defines what you may and may not do with the Entropy0 platform. It applies to all users, including those accessing the service via the web interface, the API, or the batch scanner. This AUP is incorporated by reference into the Terms of Service.
1. Intended use
Entropy0 is a B2B domain intelligence tool. It is designed for professional and organisational contexts where explainable, evidence-based domain risk signals are needed. Typical permitted uses include:
- —Threat investigation — triaging domains linked to security incidents, phishing campaigns, or alerts.
- —Fraud prevention and merchant onboarding — scoring seller, advertiser, or counterparty domains during review workflows.
- —Compliance and due diligence — assessing domain infrastructure as part of vendor, acquisition, or counterparty review.
- —Automated pipeline integration — connecting the API to internal trust and safety systems for programmatic scoring at scale.
- —Security research — investigating domain infrastructure patterns, abuse trends, or scoring methodology in a research context.
2. Prohibited uses
The following uses are prohibited regardless of plan tier:
Targeting individuals
Entropy0 scores domain-level infrastructure. It must not be used to investigate, profile, or take action against specific individuals or to infer personal characteristics from domain data.
Automated harassment or competitive intelligence scraping
Using the API to systematically scan competitor domains to extract business intelligence, or to generate bulk output for harassment or defamatory purposes, is not permitted.
Reselling raw API output
Reselling, sublicensing, or redistributing Entropy0 API responses as a standalone data product or as part of a competing service without a separate written agreement is prohibited.
Quota circumvention
Creating multiple accounts, sharing API keys across unaffiliated parties, or using technical means to bypass plan limits is prohibited and will result in account termination.
Treating scores as verdicts
Entropy0 outputs are signals, not decisions. Using scores as the sole mechanical basis for blocking payments, denying access, or taking adverse action against third parties — without human review or independent corroboration — violates the intended use of the platform.
Illegal purposes
Using the service in connection with any activity that violates applicable law, including computer fraud statutes, sanctions regulations, or data protection law, is prohibited.
3. Scan targets
Entropy0 queries publicly observable domain infrastructure (DNS records, WHOIS data, SSL certificates, and HTTP responses). This is analogous to performing a DNS lookup or visiting a website — it does not involve accessing non-public systems, exploiting vulnerabilities, or interacting with services beyond standard protocol queries.
You are responsible for ensuring your use of the platform complies with applicable law in your jurisdiction, including any obligations you may have when investigating domains related to individuals or regulated entities.
4. Enforcement
We reserve the right to investigate suspected violations of this AUP. On confirming a violation, we may take any of the following actions without prior notice:
- —Issue a warning and require corrective action.
- —Temporarily suspend API access or specific features.
- —Terminate the account immediately without refund.
- —Report activity to relevant law enforcement or regulatory authorities where required.
5. Reporting violations
If you believe the platform is being used in violation of this AUP, please report it to beta@entropy0.ai with the subject “AUP Report”.
