"Get Claude API at 90% discount?" Recently, this tempting offer has been spreading across social media and developer communities. But behind this 'special offer' lies critical security risks, account suspension, and even legal issues through illegal distribution channels.
In May 2026, as the AI API market experiences explosive growth, demand for Anthropic's Claude API has also surged. As some developers and enterprises feel burdened by official pricing and start searching for 'discounts,' illegal resellers have emerged to exploit this gap.
URGENT WARNING
This article is written to warn about the dangers of illegal API discount services. Using such services can result in account suspension, personal data breaches, financial losses, and legal liability. Please be aware.

How Illegal Discount Resellers Work - How is 90% Discount Possible?
"How on earth can they offer Claude API at 90% discount?" The answer lies in illegal and dangerous methods.
Main Illegal Distribution Channels
Hackers create Anthropic accounts using stolen credit card information and obtain API keys. They sell these keys cheaply, but the accounts are permanently suspended as soon as the card owner reports the theft.
Free or discounted accounts provided by Anthropic to educational institutions or non-profits are illegally obtained and sold commercially. This is a clear violation of terms of service.
The most dangerous method. They bypass Anthropic API access through illegal servers in China and act as intermediaries. In this process, all API call data passes through Chinese servers, posing a high risk of confidential information leakage.
One account is shared among dozens or hundreds of users. When detected by Anthropic's usage monitoring system, all users face cascading account suspensions.
Danger of Chinese Bypass Routes
In April 2026, the Korea Information Security Industry Association (KISIA) issued a warning stating that "corporate secrets and personal information may be transmitted to Chinese authorities when using AI APIs through Chinese servers." Particularly, documents, code, and customer data processed through Claude API may all be recorded on Chinese servers.

5 Deadly Risks - From Account Ban to Legal Issues
The risks of using illegal discount APIs go beyond simple "account suspension." Here are 5 deadly risks based on actual cases.
Risk 1: Sudden Account Suspension and Data Loss
In March 2026, a startup suddenly had their account suspended while using API keys purchased from an illegal reseller. This resulted in 72 hours of customer service paralysis and approximately $50,000 in revenue loss.
Risk 2: Personal Information and Confidential Data Breach
Real Case
In December 2025, a Korean company using Claude API through Chinese bypass servers discovered that 10,000 customer personal information records were leaked. All API calls were recorded while passing through Chinese servers, leading to violations of personal information protection laws.
Risk 3: Financial Fraud
Many illegal resellers use a "prepaid credit" system. However, the following fraud schemes are common:
- Take prepaid money, provide API key, then disappear
- Works normally at first, then suddenly stops service
- Demand additional fees (blackmail)
- Fake usage reports to charge additional costs
Risk 4: Legal Liability
Illegal API use is not just a terms of service violation but can be subject to criminal prosecution:
Legal Issues
- Computer Fraud: Using stolen cards can result in up to 10 years imprisonment
- Privacy Law Violation: Up to 500 million won fine for Chinese server routing
- Copyright Infringement: Civil and criminal liability for illegal API use
- Contract Breach: Anthropic can claim damages
Risk 5: Security Vulnerabilities and Malware
Some illegal resellers install malware or backdoors when providing API keys:
