Developer-first security tools block AI-manipulated attacks in under 100ms with a single API call
SafePrompt, an AI security company, today announced the general availability of its Prompt Injection Protection API. This allows developers to protect their AI applications from manipulation attacks with a single line of code. This API detects and blocks prompt injection, jailbreak, and data exfiltration attempts before they reach your AI models, addressing vulnerabilities that affect any application built on large-scale language models.
Our goal was to make security as easy and fast as Stripe makes payments. That meant one API call, transparent pricing, and no sales calls. ”
— Ian Ho, Founder of SafePrompt
Immediate insertion is the biggest security risk for AI applications. Attackers can override AI instructions to extract sensitive data, bypass security measures, or manipulate output. In a widely publicized 2023 incident, a Chevrolet dealer’s chatbot was tricked into agreeing to sell a vehicle for $1. This shows that one unprotected prompt can cause real financial harm.
SafePrompt processes most requests in less than 100 milliseconds using a multi-layered validation pipeline that combines instant pattern detection and AI-powered semantic analysis. The system identifies injection attempts, code injections (XSS, SQL), external reference attacks, and advanced multi-turn operation sequences where an attacker spreads the attack across multiple messages.
“We built SafePrompt because all developers shipping AI capabilities face the same problem: prompt injection, and the existing options are either expensive enterprise tools or brittle regular expression filters,” said Ian Ho, founder of SafePrompt. “Our goal was to make security as easy and fast as Stripe makes payments: one API call, transparent pricing, and no cold calls.”

The platform includes network intelligence that aggregates anonymized threat data from all users. When one application blocks a new attack pattern, all SafePrompt-protected applications learn from that pattern within hours. All threat data is anonymized within 24 hours to maintain GDPR and CCPA compliance.
SafePrompt offers transparent self-service pricing starting with a free tier of 1,000 verifications per month. Paid plans start at $5 per month during the beta period, standard plans at $29 per month, and $99 for higher volumes. The NPM package (@safeprompt/client) and direct HTTP API support integration with any programming language or framework.
“Every time a company connects LLM to real business logic (customer data, transactions, internal tools), the risk of prompt injection increases,” Ho said. “Developers don’t need to be security researchers to ship AI capabilities securely.”
FAQ
What is an immediate injection?
Prompt injection is an attack in which a user manipulates the instructions of an AI system by embedding hidden commands in the input. This could allow AI to leak sensitive data, circumvent safety rules, or perform unauthorized actions. SafePrompt detects and blocks these attacks before they reach your AI models.
How does SafePrompt protect AI applications?
SafePrompt uses a defense-in-depth pipeline that includes instant pattern detection for known attacks, blocking external references, and AI-powered validation for emerging threats. Developers add one API call before passing user input to the AI model. Unsafe prompts are flagged and blocked within 100ms.
What types of attacks does SafePrompt detect?
SafePrompt detects prompt injections, jailbreaks, instruction overrides, code injections (XSS and SQL), data exfiltration attempts, external reference attacks, multi-turn manipulation chains, and social engineering sequences targeting AI systems.
How much does SafePrompt cost?
SafePrompt offers a free tier of 1,000 verifications per month. Paid plans include Early Bird for $5 per month (10,000 verifications), Starter for $29 per month (10,000 verifications), and Business for $99 per month (250,000 verifications). All layers use the same core detection technology.
