HappyHorse pricing

How pricing works

Video versions are priced by the second, so a longer clip costs more credits.

HappyHorse 1.0 starts at 68 credits for a 5-second clip (≈ $0.68).

There is no subscription: top up credits when you need them and spend them on any version.

API

HappyHorse API

Every HappyHorse version on DER works over the REST API and the MCP server, with the same credits and limits as the studio. The example calls HappyHorse 1.1.
