Introduction

The TGLSC LTSLink API allows you to programmatically check URLs against 48+ web content filters used in schools and enterprises. Get real-time categorization and block status for any URL.

Account Required

API tokens are linked to your TGLSC account at glseries.net. You must be logged in to create and manage tokens.

Quick Start

1. Log in to your TGLSC account at glseries.net.

2. Create an API token from the Tokens page or sidebar.

3. Make a GET request to https://live.glseries.net/api/v1/check with your token and a URL.

4. Receive categorization results from all filters.

GET https://live.glseries.net/api/v1/check?token=gl_your_token&url=glseries.net

Available Endpoints

Endpoint	Description
/api/v1/check	Check a single URL against one or all filters
/api/v1/bulk	Check up to 3 URLs at once (each URL counts individually)
/api/v1/vs	Compare exactly 2 filters head-to-head on a URL
/api/v1/multi	Check a URL against a custom set of filters
/api/v1/filters	List all available filters (no auth required)

Streaming Mode

All check endpoints support a stream=1 parameter that returns results as a live Server-Sent Events (SSE) feed. Results appear as each filter completes instead of waiting for all filters to finish.

GET https://live.glseries.net/api/v1/check?token=gl_your_token&url=glseries.net&stream=1

Rate Limits

Limit Type	Value
Weekly requests	20,000 per token
Burst limit	10 requests per 5 seconds
Per-minute limit	60 requests per minute
Bulk URL limit	3 URLs per bulk request

Usage Counting

Each URL/domain scanned counts as one request toward your weekly limit, regardless of how many filters are run against it. For example, checking 3 URLs in a bulk request counts as 3 requests.

Response Format

All responses are returned as JSON. Successful responses include a success: true field. Streaming responses use SSE format with JSON data payloads.

TGLSC Account

All API tokens are linked to a TGLSC account. You must be logged in at glseries.net to create tokens.

API Tokens

All API requests require a valid token. Tokens are passed as a query parameter.

GET https://live.glseries.net/api/v1/check?token=gl_abc123...&url=google.com

Token Management

• Each account can create up to 5 tokens
• Tokens are permanently linked to your account
• Tokens can be enabled/disabled without deletion
• Tokens can be renamed for organization
• Deleted tokens cannot be recovered
• You can only manage tokens belonging to your account

Token Format

All tokens start with the prefix gl_ followed by 48 hexadecimal characters.

gl_a1b2c3d4e5f6...

Check URL — Single or All Filters

GET/api/v1/check

Checks a single URL against all filters, or a specific filter if specified. Supports streaming.

Parameters

Parameter	Required	Description
token	Yes	Your API token
url	Yes	URL to check (e.g. google.com)
filter	No	Filter key to check against a single filter (e.g. fortiguard)
stream	No	Set to 1 for live SSE streaming results

Usage Counting

Counts as 1 request toward your weekly limit.

Example

GET /api/v1/check?token=gl_token&url=google.com
GET /api/v1/check?token=gl_token&url=google.com&filter=fortiguard
GET /api/v1/check?token=gl_token&url=google.com&stream=1

---

Bulk Check — Multiple URLs

GET/api/v1/bulk

List Available Filters

GET/api/v1/filters

Returns a list of all available filter keys and names. No authentication required.

---

Platform Statistics

GET/api/stats

Returns the total number of checks performed on the platform. No authentication required.

---

Streaming Mode (SSE) — All Endpoints

Add &stream=1 to any check endpoint (/check, /bulk, /vs, /multi) to receive results as a live Server-Sent Events stream.

Instead of waiting for all filters to complete before receiving a response, results are pushed to you the moment each filter finishes. This is useful for:

• Displaying results progressively in a UI
• Reducing perceived latency for large scans
• Processing results as they arrive in real-time

SSE Event Types

Event Type	Description
init	Sent first — contains metadata about the scan (URLs, filter count, total checks)
result	Sent as each filter completes — contains the URL, filter key, category, blocked status, and response time
done	Sent last — indicates all filters have completed, includes usage stats

JavaScript SSE Example

const source = new EventSource(
  'https://live.glseries.net/api/v1/check?token=gl_token&url=google.com&stream=1'
);

source.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.type === 'init') {
    console.log('Scan started:', data.totalFilters, 'filters');
  }
  
  if (data.type === 'result') {
    console.log(data.filter, '→', data.category, data.blocked ? '❌ BLOCKED' : '✅ OK');
  }
  
  if (data.type === 'done') {
    console.log('All done! Used:', data.usage.weeklyUsed, '/', data.usage.weeklyLimit);
    source.close();
  }
};

Rate Limiting

API tokens have two levels of rate limiting:

• Burst: Maximum 10 requests per 5-second window
• Sustained: Maximum 60 requests per minute

When rate limited, the API returns a 429 status with a retryAfter field indicating seconds to wait.

Weekly Limit

Each token has a weekly limit of 20,000 requests. Each URL scanned counts as one request, regardless of the number of filters checked against it.

Bulk Limits

The /bulk, /vs, and /multi endpoints accept up to 3 URLs per request. Each URL counts individually toward your weekly limit.
