happyhorse-1.1-t2v, Image-to-Video happyhorse-1.1-i2v, Reference-to-Video happyhorse-1.1-r2v (up to 9 reference images for strong subject consistency), and Video Edit happyhorse-1.0-video-edit (up to 5 reference images).
Zero-cost onboarding: it shares the Wan&HappyHorse group (the former Wan group, renamed) and the same DashScope passthrough endpoint with the Wan series — existing Wan code works by changing only the model field, and one token calls both series.
Pricing is built into the APIYI system with no manual configuration: the group discount rate is 0.14x, so the default price = 0.14 × 7 (fixed exchange rate) = 0.98 — 98% of the official price; stacking recharge bonuses brings it down to ~81% of official. 720P / 1080P billed per second; failed tasks are not billed.
