Run Veo 3.1 Video Generation From Your Own Code

Google Veo 3.1 produces 4K video at up to 60fps with native audio, but integrating it directly through Vertex AI means managing IAM roles, billing accounts, and Google Cloud configuration. Wireflow wraps Veo 3.1 behind a standard REST API so you can generate videos with a single POST request and a Bearer token. The async execution pattern returns an executionId immediately, then you poll for the completed video.

The same API key works across Veo 3.1, Kling, and every other video model on the platform. Switching models means changing a node type in your workflow definition, not rewriting your integration. Rate limits scale from 10 requests per minute on the free plan to 200 per minute on Enterprise, with idempotency keys to prevent duplicate executions.

What You Get With the Veo 3.1 Video API

🎬

4K Video at 60fps

Generate up to 3840x2160 resolution video with smooth motion and native synchronized audio from text or image inputs.

🔄

Async Execution Pattern

Submit a generation request, receive an executionId, poll for status. States move from RUNNING to COMPLETED with full node outputs.

🔗

Webhook Triggers

Start video generation from forms, CI pipelines, or scheduling tools via public webhook URLs without exposing your API key.

📐

Multi-Format Output

Generate landscape, portrait, and square videos for YouTube, TikTok, Instagram Reels, and Shorts from the same workflow.

⚡

Multi-Model Routing

Switch between Veo 3.1 Standard, Fast, and Lite tiers or swap to Kling by changing a single node parameter in the request body.

🛡️

Idempotency and Rate Limits

Prevent duplicate executions with idempotency keys. Clear rate limit headers on every response with automatic retry guidance on 429s.

More Than Just Veo 3.1 Video API

Unified Video Model Access

Access Veo 3.1 alongside Kling and other video models through one API key. Compare outputs and costs without separate integrations. See how the Google Veo API feature handles model routing.

Unified Video Model Access

No Cloud Configuration

Skip Vertex AI setup, IAM roles, and Google Cloud billing. Wireflow handles authentication and infrastructure so you generate videos with curl or fetch. Follow the tutorial on generating videos with Kling AI via API for integration patterns.

No Cloud Configuration

Visual Workflow Designer

Design video generation pipelines on a node canvas before deploying them as API endpoints. Connect text inputs, image uploads, and Veo nodes visually. Learn how to access Google Veo via API for step-by-step guidance.

Production-Grade Execution

Every video generation follows a submit-poll-retrieve pattern with built-in idempotency keys and exponential backoff. Compare the async approach across the Kling AI API integration to see consistent patterns.

FAQs

What is the Veo 3.1 video API?
Veo 3.1 is Google's latest video generation model that produces 4K video at up to 60fps with synchronized audio. Wireflow provides REST API access to Veo 3.1 without requiring Google Cloud configuration.
How do I authenticate with the Veo 3.1 API?
Generate an API key from the Wireflow dashboard under Settings. Include it as a Bearer token in the Authorization header of each request. Keys begin with sk- and are shown only once.
What video resolutions does Veo 3.1 support?
Veo 3.1 generates video at 720p, 1080p, and 4K (3840x2160) resolution. The Lite tier supports 720p and 1080p, while Standard and Fast tiers support all resolutions up to 4K at 60fps.
How long are generated Veo 3.1 videos?
Each generation produces an 8-second clip. Longer videos up to approximately 148 seconds can be created by chaining multiple clips together using scene extension within a workflow.
Does Veo 3.1 generate audio with the video?
Yes. Veo 3.1 produces native synchronized audio including dialogue, ambient sound effects, and background audio. The audio is generated alongside the video, not added as a separate step.
Can I trigger Veo 3.1 generation without an API key?
Yes, using webhook triggers. Published workflows get a public webhook URL that accepts POST requests without authentication. This works for forms, CI pipelines, and third-party automation tools.
What are the rate limits for the Veo 3.1 API?
Rate limits vary by plan: Free gets 10 requests per minute with 50 daily executions, Starter gets 20 per minute with 200 daily, Pro gets 60 per minute with 1000 daily, and Enterprise gets 200 per minute with unlimited daily executions.
Can I switch between Veo 3.1 and other video models?
Yes. The same API key and execution pattern work across all supported video models. Change the node type or model parameter in your workflow definition to switch between Veo 3.1, Kling, and other models without rewriting your integration code.
