AI Content Generation API

Execute multi-model content pipelines through a single REST API with visual workflow design and async polling

AI Content Generation PipelineOpen workflow

While developing Wireflow's content generation api pipeline, we processed 200+ test generations across multiple AI models to find the configurations that produce the most reliable results. This workflow packages those findings.

Built on 200+ internal test generations during development
12+ AI models benchmarked for optimal output quality
40+ configurations tested to find the best defaults

One API Call, Multiple AI Models

Every published workflow becomes a callable REST endpoint at /api/v1/workflows/{id}/execute. Send a POST request with your Bearer sk- token, and Wireflow orchestrates text, image, and video models in sequence, returning an executionId you poll until the run completes. No separate integrations for each provider; one [model chaining](https://www.wireflow.ai/features/ai-model-chaining) pipeline handles everything.

For external triggers like forms, CI pipelines, or Zapier, use the webhook endpoint at /workflow/{webhookId}/trigger, which requires no API key and returns a 202 with the execution ID. Poll with your key to retrieve outputs from each node. This pattern makes [batch AI generation](https://www.wireflow.ai/features/batch-ai-generation) straightforward for teams producing content at scale.

What You Can Build

📝

LLM Text Generation

Use input:text nodes to feed prompts into your pipeline. Connect outputs to image or video nodes downstream for full content flows.

🖼️

Image Generation

Generate visuals with nodes like generate:flux_2_pro, generate:nano_banana_pro, or generate:imagen4 directly inside your workflow.

🎬

Video from Content

Route generated images into video:kling_video_2_5_i2v to create short-form clips as part of your content pipeline.

🔗

Multi-Model Chaining

Connect up to 100 nodes and 500 edges per workflow. Each node output feeds into the next via the React Flow graph structure.

📦

Batch Processing

Pass iteratorConfigs in your execute request to run the same pipeline across multiple inputs in a single API call.

🔑

Webhook Triggers

Each workflow can expose a no-auth webhook at /workflow/{webhookId}/trigger. External tools fire it without API keys; CORS is fully open.

More Than Just AI Content Generation API

Chain Models Visually

Connect text, image, and video models on a single canvas. Wireflow's visual workflow builder turns multi-step pipelines into drag-and-drop graphs you execute with one API call.

Chain Models Visually

Swap Models Instantly

Replace any node without rewiring the flow. Switch between Recraft V4 and Flux for images, or swap video models, while keeping the same API endpoint and execution pattern.

Swap Models Instantly

Per-Node Cost Visibility

The API returns a credit breakdown per node on 402 responses, showing exactly which step costs what. Plan your AI image generation spend before committing to a full pipeline run.

Per-Node Cost Visibility

Text to Video in One Run

Generate a script, create visuals, and animate them into clips. Teams converting text to video with AI use this pattern to produce content from a single execute call.

Text to Video in One Run

Inspect Every Step

The execution response includes outputs for each node, so you can review results at every stage. Pair with the AI image upscaler node to ensure quality before downstream processing.

FAQs

What is an AI content generation API?
It is a REST interface that accepts prompts and returns generated text, images, or video. Wireflow lets you chain multiple AI models into a single workflow and execute the entire pipeline through one API call.
Do I need coding skills to use Wireflow's API?
No. The visual node editor lets you build content pipelines without code. For programmatic access, POST to /workflows/{id}/execute with a Bearer token. No official SDK is needed; plain HTTP works.
Which AI models are available for content generation?
Wireflow supports 157 node types across text, image, and video categories. Image nodes include Flux 2 Pro, Nano Banana Pro, and Imagen 4. Video nodes include Kling 2.5. New models are added without changing existing workflows.
How does authentication work?
Generate an API key starting with sk- from your dashboard. Pass it as a Bearer token in the Authorization header. Keys support scopes like workflows:execute and executions:read for fine-grained access control.
What are the API rate limits?
Rate limits scale by plan, from 10 requests per minute on Free to 200 on Enterprise. Execution throughput caps at 10 per minute across all tiers. Daily execution limits range from 50 on Free to unlimited on Enterprise.
How does the async execution pattern work?
POST to the execute endpoint to receive an executionId immediately. Poll the /poll endpoint with exponential backoff starting at one second. Status transitions from RUNNING to COMPLETED with node outputs or FAILED with error details.
Can I trigger workflows without an API key?
Yes. Each workflow can expose a webhook endpoint at /workflow/{webhookId}/trigger that accepts POST requests without authentication. CORS is fully open, so forms, Zapier, and CI tools can trigger runs directly.
How do I prevent duplicate executions?
Include an Idempotency-Key header on your execute request. Identical keys within 24 hours replay the original response without running the workflow again, preventing accidental duplicate content generation.
