Developer-first security tool blocks AI manipulation attacks in under 100 milliseconds with a single API call
SAN FRANCISCO, CA, UNITED STATES, February 27, 2026 /EINPresswire.com/ — SafePrompt, an AI security company, today announced the general availability of its prompt injection protection API, enabling developers to shield AI applications from manipulation attacks with one line of code. The API detects and blocks prompt injection, jailbreaks, and data extraction attempts before they reach an AI model, addressing a vulnerability that affects every application built on large language models.
Prompt injection is the top security risk for AI applications. Attackers override AI instructions to extract confidential data, bypass safety measures, or manipulate output. In a widely reported 2023 incident, a Chevrolet dealership chatbot was tricked into agreeing to sell a vehicle for $1 — illustrating how a single unprotected prompt can cause real financial damage.
SafePrompt processes most requests in under 100 milliseconds using a multi-layer validation pipeline that combines instant pattern detection with AI-powered semantic analysis. The system identifies injection attempts, code injection (XSS, SQL), external reference attacks, and sophisticated multi-turn manipulation sequences where attackers spread an attack across several messages.
“We built SafePrompt because every developer shipping AI features faces the same problem — prompt injection — and the existing options were either expensive enterprise tools or fragile regex filters,” said Ian Ho, Founder of SafePrompt. “Our goal was to make prompt security as simple as Stripe made payments: one API call, transparent pricing, no sales calls.”
The platform includes network intelligence that aggregates anonymized threat data across all users. When one application blocks a new attack pattern, every SafePrompt-protected application learns from it within hours. All threat data is anonymized within 24 hours, maintaining GDPR and CCPA compliance.
SafePrompt offers transparent, self-serve pricing starting with a free tier of 1,000 validations per month. Paid plans begin at $5 per month during the beta period, with standard plans at $29 and $99 per month for higher volumes. An NPM package (@safeprompt/client) and direct HTTP API support integration with any programming language or framework.
“The risk of prompt injection grows every time a company connects an LLM to real business logic — customer data, transactions, internal tools,” said Ho. “Developers should not have to become security researchers to ship AI features safely.”
Frequently Asked Questions
What is prompt injection?
Prompt injection is an attack where a user manipulates an AI system’s instructions by embedding hidden commands in their input. This can cause the AI to leak confidential data, bypass safety rules, or perform unauthorized actions. SafePrompt detects and blocks these attacks before they reach the AI model.
How does SafePrompt protect AI applications?
SafePrompt uses a multi-layer defense pipeline: instant pattern detection for known attacks, external reference blocking, and AI-powered validation for novel threats. Developers add one API call before passing user input to their AI model. Unsafe prompts are flagged and blocked in under 100 milliseconds.
What types of attacks does SafePrompt detect?
SafePrompt detects prompt injection, jailbreaks, instruction overrides, code injection (XSS and SQL), data extraction 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 with 1,000 validations per month. Paid plans include Early Bird at $5 per month (10,000 validations), Starter at $29 per month (10,000 validations), and Business at $99 per month (250,000 validations). All tiers use the same core detection technology.
