This API contract does not promise every capability advertised for Higgsfield’s consumer products. In particular, Prompt402 does not accept 1080p or 4K for Seedance 2.5. Operational access depends on upstream availability and the service’s configured estimate and generation integration.

Which Seedance 2.5 modes are available?

New model access with transparent pricing

Seedance 2.5 is listed in Higgsfield’s current video model catalog. Prompt402 brings its text-to-video request contract into a pay-per-request x402 workflow for creative automation, video prototypes, and developer tools.

There is no fixed Seedance 2.5 price on this page. Pricing is live upstream cost plus 10%, with micro-USDC rounding. Use your intended duration, resolution, and audio settings when requesting a quote.

Sources verify the upstream model and documented parameters. Prompt402’s integration is covered by hermetic tests; no real generation or payment was used to validate this release.
