Quick start — text prompt to GLB in one API call

Sign up, copy your key, and POST a text prompt. The endpoint returns a job_id immediately. Poll GET /v1/3d/text-status/{job_id} every few seconds until status=completed, then download the GLB from output_url.

# Step 1 — submit the job
curl -X POST https://api.pixelapi.dev/v1/3d/text-generate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "prompt=a wooden treasure chest with iron bands" \
  -F "resolution=256"
# Response: {"job_id": "uuid", "status": "queued", "estimated_seconds": 75}

# Step 2 — poll until completed
curl https://api.pixelapi.dev/v1/3d/text-status/UUID \
  -H "Authorization: Bearer YOUR_API_KEY"
# Response: {"status": "completed", "output_url": "https://cdn.pixelapi.dev/..."}

What you get back

GLB — industry-standard binary glTF

A single self-contained file with mesh, UV map, and material data. Loads directly into Unity (GLTFast/UnityGLTF), Unreal Engine, Blender, Three.js, Babylon.js, and any WebGL renderer. No separate texture downloads.

Resolution control

Pass resolution=128 for lightweight meshes (prototypes, mobile assets) or resolution=256 for denser geometry (hero props, 3D print prep). Both values return the same GLB format.

Async job ID + status polling

Your POST returns a job_id within milliseconds. Poll GET /v1/3d/text-status/{job_id} at your own cadence — no held connections, no timeouts. Typical completion: 60–90 seconds.

Auto-refund on failure

If a job ends in status=failed, credits are automatically refunded to your account. You are never charged for a generation that did not produce a downloadable file.

Supported industries

The t23d API (text-to-3D) fits anywhere a developer needs 3D assets on demand without a 3D artist in the loop.

Game development

Generate prop assets, environmental details, and prototype meshes from design briefs. Pipe directly into Unity or Unreal asset import. Great for rapid prototyping and game jams where budget is tight and timelines are short.

VR / AR experiences

WebXR and ARKit/ARCore apps need GLB natively — no conversion step. Generate room decoration assets, branded objects, or interactive props from product descriptions without a modelling contractor.

3D printing pipelines

Convert text descriptions of physical objects — jewelry, figurines, enclosures — into printable mesh files. Use resolution=256 for the denser geometry that slicers (Cura, PrusaSlicer) need for clean STL conversion.

Film VFX & previz

Concept exploration and early-stage previz at zero per-asset cost. Generate 10 variations of a prop in 15 minutes, pick the direction, then hand the best mesh to a finishing modeller. Cuts first-pass modelling cost significantly.

Common 3D generation workflows

These are the most common developer patterns for the t23d API — from rapid prototyping to fully automated asset pipelines.

Batch asset generation

Submit 20 prompts in parallel (up to your concurrency limit). Collect job IDs, poll in a single loop, download when complete. Produces a full prop library overnight with no manual modelling.

Prompt-driven product configurator

Let customers describe a custom product (a personalized trophy, a branded keychain) and generate a preview mesh before they place the order. Removes the design bottleneck entirely.

Automated 3D e-commerce listing

When a new product SKU is added, trigger the t23d API with the product title as the prompt. Store the GLB alongside the 2D images for WebGL viewers (model-viewer, Three.js) and AR Quick Look.

Game content pipeline

Integrate the API into your CI/CD build — designers describe props in YAML, the pipeline calls the t23d API and imports GLBs into the game's asset registry. No artist needed for iteration.

VR world builder

Feed user-submitted room descriptions into the API to populate virtual environments. Each new user generates a unique set of objects — no two rooms are the same, at $0.010 per object.

3D print on demand

Customer submits a description ("a chess piece shaped like a robot"), API returns GLB, your backend converts to STL and sends to the printer. Full end-to-end automation for custom merchandise.

Integrations

Use the t23d API inside your existing tools and no-code platforms:

Shopify

Trigger 3D generation on new product creation. Store GLB as a product media file for 3D viewer and AR.

Make.com

No-code text-to-3D workflow. Trigger from Google Sheets, Airtable, or a form submission.

Webflow

Auto-generate GLBs for Webflow CMS product pages. Embed with model-viewer or Spline.

BigCommerce

Catalog automation: generate 3D assets for every new SKU via BigCommerce webhook.

Next.js

Server-side 3D generation in a Next.js API route. Stream progress to the client via SSE.

Zapier

Connect text-to-3D to 6,000+ apps in a no-code Zapier zap. No code required.

Comparison vs alternatives

vs Meshy

PixelAPI costs $0.010 vs Meshy's $0.020 — exactly half. Meshy has a richer GUI and more export formats; PixelAPI is built for headless developer pipelines and batch automation.

vs Tripo3D

Tripo3D starts at $0.10 per model — 10× PixelAPI's price. Good mesh quality but significantly more expensive for high-volume pipelines.

vs Rodin (Hyper3D)

Rodin uses subscription pricing with no published per-call rate. PixelAPI offers transparent pay-per-call pricing with no monthly commitment required.

vs Luma Genie

Luma's current API covers image and video generation only — no text-to-3D endpoint is available as of November 2026. PixelAPI ships a dedicated text-to-3D pipeline today.

Rate limits & error handling

Rate limits apply per API key: 20 requests/minute on the free trial, 60 on Starter, 120 on Pro, and 300 on Scale. Parallel jobs per key: 3 / 10 / 20 / 50. Exceeding the limit returns HTTP 429 with a Retry-After header. Recommended backoff: start at 5s, double on each retry up to 60s. The PixelAPI SDKs handle this automatically.

# Python SDK — automatic retry on 429
from pixelapi import PixelAPI
client = PixelAPI(api_key="...", max_retries=4)

# Submit and wait — retries 429 with backoff automatically
result = client.text_to_3d(prompt="a low-poly oak tree", resolution=256)
result.save("tree.glb")

If your job returns status=failed, credits are refunded automatically and error_message in the status response explains why. Common causes: prompts that describe complex multi-object scenes (use single-object prompts for best results), or prompts that trigger the content safety filter.

Frequently asked questions

How does the t23d API compare to Meshy?

PixelAPI's t23d API generates GLB 3D models from text prompts at $0.010 per model — exactly half Meshy's $0.02 price. Both deliver downloadable 3D mesh files via a REST API. Meshy offers more export formats (OBJ, FBX, USDZ) and a GUI editor; PixelAPI is optimized for headless developer pipelines and batch automation.

What does the t23d API cost?

$0.010 per 3D model. That is exactly half Meshy's $0.02 per-model price. New accounts get 300 free credits — enough for 30 free 3D generations — with no credit card required.

What 3D output formats does the API return?

The API returns a GLB file (binary glTF). GLB is the industry-standard format for real-time 3D: it loads natively in Unity, Unreal Engine, Blender, Three.js, Babylon.js, and <model-viewer>. It is self-contained — mesh, texture, and materials in one download, no sidecar files.

How do I call the text-to-3D API?

POST your prompt to https://api.pixelapi.dev/v1/3d/text-generate with your Bearer token. The response returns a job_id immediately. Poll GET /v1/3d/text-status/{job_id} every 5–10 seconds until status=completed, then fetch the GLB from output_url. See the Quick Start section above for copy-paste code in 6 languages.

How long does text-to-3D generation take?

Most jobs complete in 60–90 seconds. The pipeline converts your text description to an intermediate image, then extracts the 3D mesh. The API is fully async — your POST returns in milliseconds so there is no timeout risk on your HTTP client.

What prompts work best for text-to-3D?

Single-object prompts with clear shape and material descriptions produce the cleanest meshes: "a futuristic sci-fi helmet", "a ceramic coffee mug with a curved handle", "a low-poly pine tree". Prompts must be 3–500 characters. Avoid describing full scenes with multiple objects or backgrounds — those tend to produce muddy geometry.

Is there a free trial?

Yes. New accounts receive 300 free credits — enough for 30 text-to-3D models — with no credit card required. The trial is per-account and covers any tool on PixelAPI, not just the t23d endpoint.

What are the rate limits?

20 requests/minute on the free trial, 60 on Starter, 120 on Pro, and 300 on Scale. Parallel concurrent jobs: 3/10/20/50 respectively. HTTP 429 responses include a Retry-After header. The Python and Node.js SDKs handle retry with exponential backoff automatically — no extra code needed.

Does the API support image-to-3D as well?

Yes. POST an image to https://api.pixelapi.dev/v1/3d/generate to generate a 3D mesh from a photo. That endpoint uses the same async polling pattern and also returns GLB, at $0.010 per model. See the API docs for the full endpoint reference.

Can I use the GLB in Unity or Unreal Engine?

Yes. GLB is the preferred 3D import format for both Unity (via the GLTFast or UnityGLTF package) and Unreal Engine (via the glTF importer plugin). It also loads natively in Blender, Three.js, Babylon.js, and any <model-viewer> WebGL renderer. No conversion step required.

What happens if generation fails?

If a job ends with status=failed, your credits are automatically refunded. You are never charged for a generation that did not produce a downloadable file. The error_message field in the status response explains the failure reason.

Is there a Python SDK?

Yes — pip install pixelapi. The SDK handles authentication, async polling, retry-on-429, and returns the GLB bytes for direct file saving. Official SDKs also cover Node.js (npm install pixelapi), PHP (Composer), Ruby (Gem), and Go (go get).
