Game Asset Generator
htdt/godogen
Generates game art from text prompts: PNG images, GLB 3D models, rigged characters, animations and sprites, with background removal.
A skill your agent uses whenever an LLM agent needs to search, browse, or download 3D models from Poly Pizza (poly.pizza) using their REST API.

poly-pizza-apiA skill your agent uses whenever an LLM agent needs to search, browse, or download 3D models from Poly Pizza (poly.pizza) using their REST API.
Poly Pizza API is an agent skill from jasonkneen/tiny-world-builder. Use this skill whenever an LLM agent needs to search, browse, or download 3D models from Poly Pizza (poly.pizza) using their REST API. Triggers on any task involving: finding free low-poly 3D models, searching the Poly Pizza catalogue, fetching model metadata or download URLs, retrieving popular models, or downloading .glb files from Poly Pizza. Use this skill proactively whenever the agent needs to obtain 3D assets programmatically, even if the user just says "find me a 3D model of X" without mentioning Poly…
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering 3D graphics and WebGL, Game assets and audio and REST APIs. The licence is AGPL-3.0.
2 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit a2a1129. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are http, python and json).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
api.poly.pizzapoly.pizzaFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
POLY_PIZZA_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Poly Pizza API loads about 1.9k tokens when it runs. Until then it costs about 136 tokens; SKILL.md has 496 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/poly-pizza-api/SKILL.md (or your agent's skills folder).Poly Pizza (https://poly.pizza) hosts 10,000+ free low-poly CC0 and CC-BY 3D models. The API lets agents search, filter, and download them programmatically.
All requests require an API key obtained from https://poly.pizza/settings/api (requires
a free account). In this environment, the key is available as the POLY_PIZZA_KEY
environment variable. Pass it as a header:
X-Auth-Token: <your_api_key>The key must be present on every request. There is no OAuth flow — it's a static token.
https://api.poly.pizza/v1/All endpoints below are relative to this base.
GET /search/{query}Returns models matching the keyword. URL-encode the query string.
Query parameters:
| Param | Type | Default | Description |
|---|---|---|---|
limit | integer | 12 | Max results to return (max ~50) |
cursor | string | — | Pagination cursor from a previous response |
format | string | "glb" | File format filter (glb, fbx, obj) |
animated | boolean | — | Filter to only animated models |
tricount | string | — | Triangle count range, e.g. "0-5000" |
Example:
GET https://api.poly.pizza/v1/search/tree?limit=5
X-Auth-Token: your_key_hereResponse shape:
{
"cursor": "some_cursor_string_or_null",
"results": [

}
// ... more results
]
}GET /popularReturns the most popular / trending models on the site.
Query parameters: same as search (limit, cursor, format, animated, tricount)
Example:
GET https://api.poly.pizza/v1/popular?limit=10
X-Auth-Token: your_key_hereResponse shape is identical to search.
GET /model/{id}Returns full metadata for a single model by its unique ID.
Example:
GET https://api.poly.pizza/v1/model/5EGWBMpuXq
X-Auth-Token: your_key_hereResponse is a single model object (same shape as an entry in results above).
The Download field in the response is a direct CDN URL to the .glb file. To download
it, perform a plain GET request — no auth header required on the CDN URL itself.
import requests
# First, search for the model
headers = {"X-Auth-Token": api_key}
resp = requests.get("https://api.poly.pizza/v1/search/chair", headers=headers, params={"limit": 1})

Always check model.Licence and record credits for CC-BY models. A minimal attribution
line looks like:
"Oak Tree" by someartist (https://poly.pizza/u/someartist) CC-BY 4.0Responses include a cursor field. If it's non-null, there are more results. Pass it as
?cursor=<value> on the next request (keep all other params the same).

| 200 | OK |
| 401 | Missing or invalid API key |

| 429 | Rate limit exceeded — back off |
| 500 | Server error — retry |
On 429, wait at least 1 second before retrying. The API has no documented rate limit ceiling; hobbyist use is free, commercial use is pay-as-you-go.

A skill your agent uses whenever an LLM agent needs to search, browse, or download 3D models from Poly Pizza (poly.pizza) using their REST API. Poly Pizza API is an agent skill from jasonkneen/tiny-world-builder.pizza) using their REST API.
Poly Pizza API fits situations like: an LLM agent needs to search; download 3D models from Poly Pizza (poly.pizza) using their REST API; any task involving: finding free low-poly 3D models; searching the Poly Pizza catalogue.
Run `npx skills add jasonkneen/tiny-world-builder --skill poly-pizza-api -a claude-code`. Or copy the skill folder (.agents/skills/poly-pizza-api in jasonkneen/tiny-world-builder) into .claude/skills/poly-pizza-api in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jasonkneen/tiny-world-builder --skill poly-pizza-api -a codex`. Or copy the skill folder (.agents/skills/poly-pizza-api in jasonkneen/tiny-world-builder) into .agents/skills/poly-pizza-api in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jasonkneen/tiny-world-builder --skill poly-pizza-api -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/poly-pizza-api, .gemini/skills/poly-pizza-api, .github/skills/poly-pizza-api and .opencode/skills/poly-pizza-api in your project.
Going by SKILL.md and its folder, Poly Pizza API needs credentials named POLY_PIZZA_KEY. Our summary lists: Python 3; A credential in POLY_PIZZA_KEY.
SKILL.md names 2 domains. In commands or code: api.poly.pizza and poly.pizza; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Poly Pizza API is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Poly Pizza API: Game Asset Generator (htdt/godogen, 7.1k stars), Threejs 3D Generator (valkor-ai/loom, 1.2k stars), Asset Pipeline (rehan-remade/universal-modder, 5.8k stars) and Blender Image To 3D (majidmanzarpour/blender-game-skills, 135 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
