Overview

The Sentinel REST API provides HTTP endpoints for AI safety validation, seed retrieval, and chat functionality.

Features:

• THSP (Truth, Harm, Scope, Purpose) validation
• Jailbreak detection
• Alignment seed retrieval
• Chat with automatic seed injection
• Safety benchmarking

Base URL

Production: https://api.sentinelseed.dev
Local:      http://localhost:8000

Running Locally

cd sentinel/api
uvicorn main:app --reload

Authentication

Currently, the API does not require authentication for basic operations.

For chat and benchmark endpoints, you need to set API keys as environment variables:

export OPENAI_API_KEY="sk-..."
# or
export ANTHROPIC_API_KEY="sk-..."

Endpoints

HTTP Status Codes

Common Errors

Invalid Seed Level (400):

{
  "detail": "Invalid seed level. Options: minimal, standard, full"
}

Missing Required Field (422):

{
  "detail": [
    {

Rate Limiting

Currently, the API does not enforce rate limiting. For production deployments, consider implementing rate limiting at the infrastructure level.

Recommended limits:

• /validate: 100 requests/minute
• /chat: 20 requests/minute
• /benchmark: 1 request/minute

Examples

Python (requests)

import requests

BASE_URL = "https://api.sentinelseed.dev"

# Validate text
response = requests.post(
    f"{BASE_URL}/validate",
    json={"text": "Hello, world!"}
)
result = response.json()
print(f"Safe: {result['is_safe']}")

# Get seed
response = requests.get(f"{BASE_URL}/seed/standard")
seed = response.json()["content"]

# Pre-validate request
response = requests.post(
    f"{BASE_URL}/validate/request",
    json={"request": "Help me with Python"}
)
if response.json()["should_proceed"]:
    # Proceed with LLM call
    pass

JavaScript (fetch)

const BASE_URL = "https://api.sentinelseed.dev";

// Validate text
async function validateText(text) {
  const response = await fetch(`${BASE_URL}/validate`, {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ text })
  });
  return response.json();
}

// Usage
const result = await validateText("Hello, world!");
console.log("Safe:", result.is_safe);
