HappyHorse API Pricing on EvoLink: Credits, Quality, and Cost Planning
HappyHorse API Pricing on EvoLink
Current EvoLink Pricing Scope
The current HappyHorse pricing implementation uses per-second billing for video generation:
| Quality | Pricing basis |
|---|---|
| 720p | 12.15 credits/s |
| 1080p | 1.778x the 720p rate |
This is the route pricing used by EvoLink's HappyHorse page. It should not be mixed with Artificial Analysis, vendor-side, or third-party pricing unless the source and scope are clearly labeled.
Simple Cost Formula
For normal generation routes, start with:
duration x credits per second x quality multiplier = estimated creditsExamples:
| Example | Formula | Estimated credits |
|---|---|---|
| 5s at 720p | 5 x 12.15 | 60.75 credits |
| 10s at 720p | 10 x 12.15 | 121.5 credits |
| 5s at 1080p | 5 x 12.15 x 1.778 | ~108.01 credits |
| 10s at 1080p | 10 x 12.15 x 1.778 | ~216.03 credits |
Use these as planning estimates, then confirm in the live Playground before production.
Workflow Differences
| Workflow | Billing note |
|---|---|
| Text to video | Billed by output duration and selected quality |
| Image to video | Billed by output duration and selected quality |
| Reference to video | Billed by output duration and selected quality |
| Video edit | Billed by total duration rules: input video duration plus output video duration, with source duration capped for billing |
The video edit route is the one to watch carefully. If you are editing source videos, do not use a simple output-duration-only estimate.
720p vs 1080p
- you are testing prompt quality
- you are comparing HappyHorse against Seedance or Kling
- you need more iterations for the same budget
- the output is for internal review or social draft testing
- the creative direction is already approved
- the video is customer-facing
- detail retention matters more than iteration volume
- the clip will be used in a polished campaign or demo
Budget Planning Tips
- Run first-pass prompts at 720p.
- Keep durations short while comparing models.
- Reserve 1080p for final candidates.
- Track retry rate, not only successful output cost.
- Compare HappyHorse, Seedance, and Kling inside one EvoLink workflow before choosing a default route.
