Execute multi-step AI pipelines via a single REST endpoint with no SDK required

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.
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.
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.
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.
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
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.
