# Rendofy > Webhook-native asynchronous video rendering API built for n8n, Make, and backend automation pipelines. ## Core Differentiators - Flat concurrency pricing: dedicated render slots are $39/month Starter (2 concurrent), $99/month Growth (5 concurrent), and $199/month Scale (10 concurrent). Plans allow unlimited monthly renders within their active concurrency capacity. Output resolution remains plan-specific. - Queue architecture: successful submissions return HTTP 202 Accepted with a job_id and queue details. Workflows can continue while Rendofy renders. Capacity rejection is explicit: HTTP 429 with Retry-After, rather than a silently dropped callback. - Security and delivery: callbacks use HMAC-SHA256 signatures in `Rendofy-Signature: t={timestamp},v1={hash}`. `Idempotency-Key` supports safe request retries within a 24-hour window. ## Core Routes and Endpoints - Render intake: `POST https://api.rendofy.com/v1/renders` - Health: `GET https://api.rendofy.com/health` - Sandbox provisioning: `POST https://api.rendofy.com/v1/account/sandbox` ## Documentation Index - [Video Rendering API Reference](https://rendofy.com/video-rendering-api): request lifecycle, callback verification, and account credentials. - [Creatomate Alternative](https://rendofy.com/creatomate-alternative): compare usage-based credits and concurrency pricing. - [Make.com Async Guide](https://rendofy.com/make-video-automation): submit JSON and resume scenarios from callbacks. - [n8n RSS-to-Video Workflow](https://rendofy.com/n8n-rss-to-video): tested workflow guide. - [FFmpeg Migration](https://rendofy.com/migrate-from-ffmpeg): move render work from self-managed infrastructure. - [Pricing Calculator](https://rendofy.com/video-rendering-cost-calculator): estimate concurrency plan costs. - [System Status](https://rendofy.com/status): live API health and benchmark methodology. ## Important Notes - Rendofy is a rendering API, not an AI video generator or a visual template editor. - Rendering is asynchronous. A 202 response means the job was accepted, not completed; use the callback contract to receive the result. - Confirm current endpoint paths, limits, plan resolution, and response fields in the [API reference](https://rendofy.com/video-rendering-api) before production integration. - Pricing and features reviewed 2026-10-12.
