AI Workflow API

Our internal testing of 1000+ workflow api outputs across 33+ model variants revealed clear best practices for prompt structure, model selection, and output settings — all reflected in the workflow below.

Built on 1000+ internal test generations during development
15+ AI models benchmarked for optimal output quality
50+ configurations tested to find the best defaults

One API Call, Multiple AI Models

Traditional AI integrations require separate API calls, custom glue code, and per-model error handling. Wireflow consolidates this into a single POST /api/v1/workflows/{id}/execute request that returns an executionId. Poll GET /api/v1/workflows/executions/{id}/poll until the state transitions from RUNNING to COMPLETED, then read the full node outputs. Each node processes its input and passes results downstream automatically, supporting up to 100 nodes and 500 edges per workflow. Explore how [AI model chaining](https://www.wireflow.ai/features/ai-model-chaining) connects generation, editing, and output nodes in sequence.

API Capabilities

🔗

157+ Node Types

Connect Flux 2, Recraft v4, Kling Video 2.5, Imagen 4, and dozens more AI models in a single pipeline, all accessible through one unified REST interface.

📡

Bearer Token Auth

Generate API keys (sk-...) from Settings > API Keys. Authenticate every request with a single Authorization: Bearer header. No OAuth flows or complex handshakes needed.

⚡

Async Execution with Polling

POST to execute returns immediately with an executionId. Poll with exponential backoff (start 1s, x1.5, cap 10s) until COMPLETED or FAILED. No open connections to manage.

🔄

Webhook Triggers (No Auth Required)

Each workflow can expose a webhook URL at POST /workflow/{webhookId}/trigger. Fire from Zapier, CI pipelines, or HTML forms with no API key needed on the trigger call.

🧩

React Flow JSON Definitions

Define workflows as JSON graphs with typed nodes (model, input, utility, output, logic categories) and edges. Create, update, and version workflows entirely via the API.

📊

Node-Level Execution Logs

GET /workflows/executions/{id} returns per-node timing, credit costs, and outputs. Every response includes X-Request-Id for tracing issues with support.

More Than Just AI Workflow API

Predictable Rate Limits

Every plan gets clear rate-limit headers (X-RateLimit-Limit, Remaining, Reset) on every response. Pro plans allow 60 requests/min and 1,000 daily executions. Check pricing for full tier details.

Predictable Rate Limits

Idempotent Executions

Pass an Idempotency-Key header on execute calls. Identical keys within 24 hours replay the original response without duplicate runs. Combine with pipeline automation for reliable batch processing.

Idempotent Executions

No Infrastructure Management

Skip server provisioning, GPU allocation, and model hosting. Wireflow runs every node on optimized infrastructure behind the API. Learn how to build AI workflows without code and deploy endpoints in minutes.

No Infrastructure Management

Granular Credit Transparency

If a workflow exceeds your balance, the API returns 402 with a breakdown showing exactly which nodes cost how many credits. See enterprise plans for unlimited daily executions.

Claude Skill Integration

Wireflow publishes an official Claude Skill that lets Claude Code or Claude Desktop drive workflows via this API. Use it with reusable AI templates for agentic multi-step generation patterns.

FAQs

What is an AI workflow API?
An AI workflow API is a REST endpoint that executes multi-step AI pipelines. You send one POST request to /api/v1/workflows/{id}/execute with your inputs, receive an executionId, and poll until the full pipeline completes.
How many AI models can I chain in one workflow?
Wireflow supports up to 100 nodes and 500 edges per workflow. You can chain any combination of 157+ node types including Flux 2, Kling Video, Imagen 4, Recraft v4, and utility nodes for prompt processing.
Do I need an SDK to use the API?
No. Wireflow has no official SDK. It is plain REST and JSON. Any HTTP client works: curl, fetch, axios, Python requests, Go net/http. Authenticate with a Bearer sk- token and you are ready.
What programming languages work with the API?
Any language that can make HTTP requests. The API accepts JSON payloads and returns JSON responses. Common choices are JavaScript (fetch/axios), Python (requests), Go, Ruby, and curl for scripting.
How does the API handle long-running tasks like video?
The API uses an async execution pattern. POST to execute returns immediately with an executionId. Poll GET /workflows/executions/{id}/poll with exponential backoff (start 1s, x1.5, cap 10s) until status is COMPLETED or FAILED.
Can I trigger workflows without an API key?
Yes, via webhooks. Each workflow can expose a webhook URL (POST /workflow/{webhookId}/trigger) that requires no authentication. This works with Zapier, CI pipelines, HTML forms, or any system that can send HTTP POST requests.
What are the rate limits?
Limits vary by plan: Free allows 10 req/min and 50 daily executions, Pro allows 60 req/min and 1,000 daily, Enterprise gets 200 req/min unlimited. Execution cap is 10/min on all tiers.
How do I prevent duplicate executions on retries?
Send an Idempotency-Key header with your POST /execute call. Identical keys within 24 hours replay the original response without triggering a new execution, making it safe for network retry logic.
