This API requires no authentication and returns JSON data. Ideal for building game companions, crafting calculators, or AI-powered assistants.
Base URL
https://molochdagod.github.io/ObjectStore
All endpoints are relative to this base URL. For example:
GET https://molochdagod.github.io/ObjectStore/api/v1/weapons.json
Authentication
No Auth Required
The ObjectStore API is completely public. No API keys, tokens, or authentication headers are needed. Simply make HTTP GET requests to any endpoint.
This API only serves static game definitions. For player-specific data (inventory, characters, progress), you'll need authenticated access to our Supabase database. See Database Schema for details.
Weapons Endpoint
Returns all weapon definitions organized by category. Each weapon includes stats, abilities, lore, and crafting requirements.

| Aseprite JSON + PNG | Parses .json atlas for frame rects (array or object format) | Drop both files together |
AI-Assisted Detection
Click 🤖 AI Detect Layout to send a thumbnail to GPT-4o vision. The AI identifies the frame grid, character type, and animation type, then pre-fills all parse settings automatically.
Save Options

- Save to Puter Cloud — Uploads PNG + metadata JSON to Puter cloud storage (
grudge-sprites/{category}/).
Puter.js Integration
The ObjectStore uses Puter.js v2 for free, serverless AI and cloud storage — no API keys or backend needed.
APIs Used
| API | Purpose |
|---|---|
puter.ai.chat() | Vision analysis, sprite editing chat, streaming responses |
puter.ai.txt2img() | Sprite generation with GPT Image 1.5 |
puter.fs.write() | Save sprites to Puter cloud storage |
puter.kv.set()/get() | Persist chat history and user preferences |
Puter.js uses a user-pays model — each user's Puter account covers their own AI usage. Developers pay nothing regardless of scale.

Python Examples
import requests
BASE_URL = "https://molochdagod.github.io/ObjectStore/api/v1"
# Get all weapons
weapons = requests.get(f"{BASE_URL}/weapons.json").json()
# Find all swords
swords = weapons["categories"]["swords"]["items"]
print(f"Found {len(swords)} swords")
# Get materials
materials = requests.get(f"{BASE_URL}/materials.json").json()
# Find T5+ ores
high_tier_ores = [m for m in materials["materials"]
if m["category"] == "ore" and m["tier"] >= 5]
Search API (Serverless)
Serverless search across all ObjectStore data. Searches weapons, armor, materials, consumables, enemies, bosses, skills, and sprites.
Parameters
| Param | Required | Default | Description |
|---|---|---|---|
q | Yes | — | Search query string |
type | No | all | Filter by type: weapons, armor, materials, consumables, enemies, bosses, skills, sprites |
limit | No | 50 | Max results (1-200) |
Example
GET /api/search?q=iron&type=materials&limit=10
{
"query": "iron",
"type": "materials",
"totalResults": 3,
"results": [
{ "type": "material", "id": "iron-ore", "name": "Iron Ore", "category": "ore", "tier": 2 },

}
The /api/search and /api/stats endpoints are serverless functions available only when deployed on Vercel. The static JSON files work on both GitHub Pages and Vercel.
Stats API (Serverless)
Returns aggregate statistics for all ObjectStore data — total counts by category, available endpoints, and browser pages.
AI Integration
The ObjectStore API is designed for AI agent consumption:
- No Authentication - Direct HTTP access
- JSON Format - Easy to parse
- Stable Schema - Rarely changes
- Complete Data - All game definitions in one place
Game data updates infrequently. Cache API responses for 24 hours to reduce requests and improve performance.
Example: AI Crafting Assistant
// Fetch required data
const [weapons, materials] = await Promise.all([
fetch(BASE_URL + '/weapons.json').then(r => r.json()),
fetch(BASE_URL + '/materials.json').then(r => r.json())
]);
// Helper: Get materials needed for a weapon
function getCraftingRequirements(weaponId, tier) {
const weapon = findWeapon(weapons, weaponId);
const tierMaterials = materials.materials.filter(m => m.tier === tier);
return {
weapon: weapon.name,
tier: tier,
profession: weapon.craftedBy,
primaryMaterial: tierMaterials.find(m =>
m.gatheredBy === weapon.craftedBy
)
};
