A developer-first REST API for multi-model image and video generation, without the consumer UI overhead of Krea AI
Free to build · no credit card
We spent 25+ hours benchmarking AI models for krea api while building Wireflow, documenting which settings and configurations produce the best outputs. The workflow below reflects what we learned.
What the Krea AI API Does
Krea AI's API bundles 40+ image and video generation models behind a single REST endpoint. Developers send a POST request, receive a job ID, then poll for results or wait for a webhook callback. The model roster includes Flux variants, Imagen 4, Seedream, Veo 3, Kling, and Sora 2, all billed in compute units (CU) rather than flat per-call fees.
The main limitation developers encounter is that Krea is a consumer creative platform first. The API is well-documented but secondary to the studio UI, and support is Discord-only below the $200/month Business tier. Developers building production pipelines often hit friction around rate limit transparency, webhook reliability, and the absence of an official typed SDK.
Wireflow API Capabilities
Single REST endpoint
One base URL covers workflow creation, execution, polling, and webhook triggers — no model-specific SDKs to integrate separately.
Async execution with polling
POST to /workflows/{id}/execute, get an executionId back, then poll with exponential backoff or receive results via webhook.
Multi-model chaining
Chain image generators, upscalers, background removers, and video models in one workflow call rather than managing sequential API calls yourself.
Webhook triggers
POST to /workflow/{webhookId}/trigger requires no API key — ideal for Zapier integrations, form submissions, and CI-triggered media generation.
Transparent rate limit headers
Every response includes X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, and Retry-After on 429s so you can build resilient clients.
Idempotency and credit tracking
Send an Idempotency-Key header to prevent duplicate executions within 24 hours. 402 responses include a per-node credit breakdown for cost control.
More Than Just krea ai api
High-volume batch generation
Krea's free tier caps at 100 compute units per day. For production-scale jobs, Wireflow's batch image generation API handles queue management and parallel execution natively.
No consumer UI tax
Krea bundles its studio UI into every plan, so API developers pay for features they never use. Wireflow separates the canvas from API pricing. See how to run batch image generation via API for a practical comparison.
Visual canvas plus code-level control
Design pipelines on a drag-and-drop canvas, publish them as callable endpoints, and invoke them from code. Learn how to build AI workflows without writing backend code for non-technical team members.
Model-level output quality
Generate with Flux 2 Pro, Recraft V4, Nano Banana, or Imagen 4. Wireflow's Recraft V4 model produces high-fidelity design assets and brand illustrations in a single API call.
Predictable dollar-cost pricing
Krea's compute unit model requires mental math to convert CU to dollars. Wireflow publishes clear per-execution credit costs. Read Flux Pro API pricing and code examples to see how costs scale with volume.
