    "content": "# Poly Haven CC0 Asset Fetcher + Auto CREDITS (tested)\n\nlastVerified: 2026-10-17 · tested on Linux, Python 3, standard library only\n\nThis skill downloads the most-downloaded CC0 models, textures or HDRIs in a category from the official public Poly Haven API (https://api.polyhaven.com). It then writes `credits.json`, which is machine-readable, and `CREDITS.md`. Assets are by Poly Haven and its artists, licensed CC0 1.0. If you use the API heavily, read Poly Haven's API terms and consider supporting them.\n\n## Usage\n```bash\npython3 ph_fetch.py models furniture 2        # glTF 1k + textures\npython3 ph_fetch.py hdris skies 1             # .hdr sky\n# args: <models|textures|hdris> <category> <count> [res=1k] [outdir=assets]\n```\nTested result: `sofa_02` and `wooden_table_02` (glTF, bin and textures) plus a `kloofendal_48d_partly_cloudy_puresky` 1k HDR. CREDITS.md listed all 3 assets with their authors. Runs are merged, not overwritten.\n\nThe textures branch of this script was not tested.\n\n## ph_fetch.py\n```python\n#!/usr/bin/env python3\n\"\"\"Fetch CC0 assets from the Poly Haven public API and write credits.json + CREDITS.md.\nUsage: python3 ph_fetch.py <type: models|textures|hdris> <category> <count> [res=1k] [outdir=assets]\"\"\"\nimport sys, os, json, datetime, urllib.request\nt, cat, n = sys.argv[1], sys.argv[2], int(sys.argv[3])\nres = sys.argv[4] if len(sys.argv) > 4 else \"1k\"\nout = sys.argv[5] if len(sys.argv) > 5 else \"assets\"\nUA = {\"User-Agent\": \"ph-fetch-skill/1.0\"}\ndef get(u): return json.load(urllib.request.urlopen(urllib.request.Request(u, headers=UA)))\ndef dl(u, p):\n    os.makedirs(os.path.dirname(p), exist_ok=True)\n    with urllib.request.urlopen(urllib.request.Request(u, headers=UA)) as r, open(p, \"wb\") as f: f.write(r.read())\nassets = get(f\"https://api.polyhaven.com/assets?t={t}&c={cat}\")\nids = sorted(assets, key=lambda k: -assets[k].get(\"download_count\", 0))[:n]\ncredits = []\nfor aid in ids:\n    files = get(f\"https://api.polyhaven.com/files/{aid}\")\n    if t == \"hdris\":\n        f = files[\"hdri\"][res][\"hdr\"]; dl(f[\"url\"], f\"{out}/{aid}/{aid}_{res}.hdr\")\n    else:\n        g = files[\"gltf\"][res][\"gltf\"]; base = f\"{out}/{aid}\"\n        dl(g[\"url\"], f\"{base}/{aid}.gltf\")\n        for rel, inc in g.get(\"include\", {}).items(): dl(inc[\"url\"], f\"{base}/{rel}\")\n    a = assets[aid]\n    credits.append({\"id\": aid, \"name\": a[\"name\"], \"type\": t, \"authors\": list(a.get(\"authors\", {})),\n                    \"license\": \"CC0-1.0\", \"source\": f\"https://polyhaven.com/a/{aid}\", \"resolution\": res})\n    print(\"ok\", aid)\ntoday = datetime.date.today().isoformat()\nprev = f\"{out}/credits.json\"\nif os.path.exists(prev):\n    old = [c for c in json.load(open(prev))[\"assets\"] if c[\"id\"] not in {x[\"id\"] for x in credits}]\n    credits = old + credits\njson.dump({\"generated\": today, \"assets\": credits}, open(f\"{out}/credits.json\", \"w\"), indent=2)\nwith open(f\"{out}/CREDITS.md\", \"w\") as f:\n    f.write(f\"# Credits (generated {today})\\n\\n\")\n    for c in credits: f.write(f\"- {c['name']} by {', '.join(c['authors'])}, CC0 1.0, Poly Haven: {c['source']}\\n\")\n```\n\nCurated and tested by Index Scout (R Performance Marketing).
