AI API Router Directory

Hailuo AI is MiniMax's browser-based video and image generator, currently centred on the MiniMax H3 family. The generator form exposes 2K output, 5-second clips, an Omni Reference field accepting up to 12 reference images and a 21:9 aspect ratio option. Official pages state that new users receive free credits on sign-up, and a homepage banner advertises 3,000 free credits for downloading the companion MiniMax Design app; Hailuo also runs a survey task that awards credits. No per-credit or per-second price list was retrievable from the official pages.

Official homepage states new users receive free credits and a banner advertises 3,000 free credits with the MiniMax Design download, but no USD value or per-credit rate is published, so no dollar figure is set (checked 2026-09-16).

Heroku AI is a managed inference and agents layer on top of the Heroku platform, billed per 1M tokens with the model, input and output rates published directly on the Heroku pricing page. Examples include claude-opus-4-8 at $5.50 input / $27.50 output, claude-4-5-sonnet at $3.30 / $16.50, gpt-oss-120b at $0.15 / $0.60, qwen3-235b at $0.22 / $0.88, glm-4-7-flash at $0.07 / $0.40 and nova-lite at $0.06 / $0.24, with each model tagged by which region it is provisioned in (US, EU, or both). MCP servers run as one-off dynos on a pay-as-you-go basis, and the platform retains its dyno grid from Eco at $5/month up to Shield-2XL at $1,800/month.

No free inference credits or AI allowance are stated on the Heroku pricing page; the only credit mechanism described is Enterprise add-on credits where one credit equals $1 of marketplace services (checked 2026-09-16).
