Javelin OpenAPI Specifications

OpenAPI specifications for Javelin's AI security platform APIs.

Overview

This repository contains OpenAPI 3.0.3 specifications for Javelin's standalone guardrails API, providing comprehensive documentation for developers integrating with Javelin's AI security services.

Available APIs

Standalone Guardrails API

File: standalone-guardrails-openapi.json

The standalone guardrails API allows you to evaluate content against security guardrails independently of LLM request/response processors. This enables proactive content screening, policy validation, and threat detection.

Supported Guardrails:

• Prompt Injection Detection - Detect prompt injection attempts and jailbreak techniques
• Trust & Safety - Detect harmful content across categories (violence, weapons, hate speech, crime, sexual content, profanity)
• Language Detection - Detect language with confidence scores and enforce language policies

Base URL: https://your-javelin-backend-url

Authentication: API Key via x-javelin-apikey header

API Documentation

Request Format

All guardrails use a standardized request format:

{
  "input": {
    "text": "Content to analyze"
  },
  "config": {},    // Optional configuration
  "metadata": {}   // Optional metadata
}

Response Format

Responses include detailed assessments with:

• Categories: Boolean flags for each threat category
• Category Scores: Confidence scores (0.0-1.0) for each category
• Request Reject: Boolean flag indicating if content should be rejected based on policy

Application Policies

Use the x-javelin-application header to apply application-specific policies:

• Inspect Mode: request_reject will be false even if threats are detected
• Reject Mode: request_reject will be true when threats exceed configured thresholds
