Why through VisionX

One contract instead of five vendor relationships

Standing up direct API relationships means five procurement cycles, five quota negotiations, and five support queues. The reseller path collapses that into one.

Authorized, not grey-market

Official, supported access to Seedance and Seedream APIs. Real quotas, real support paths, and continuity a proxy can't promise.

One contract, many models

The guest engines on our roster ride the same relationship, so adding a model to your product is a scope change, not a procurement cycle.

Volume terms under MSA

Rates, quotas, and support scoped to your actual volume, founder-led. You talk to the people who run the infrastructure.

What it looks like

A generation is one POST away.

The engine ladder your contract covers is the same one the studio meters: draft tiers for volume work, Cinema for native-4K masters, image routes for stills.

  • Text-to-video, image-to-video, video-to-video, and image generation.
  • Native 4K masters on the Cinema tier, no upscale pass required.
  • Async task lifecycle with polling, the same contract the studio runs on.

Engine names below are illustrative of the studio ladder: Seedance 1.0 lite to Seedance 2.0 on video, plus the Seedream image family.

FAQ

API access, answered

What does "authorized reseller" mean here?
VisionX holds an official reselling relationship with BytePlus. API access to Seedance video and Seedream image models through us is supported vendor access with real quotas and support paths, not a grey-market proxy that can disappear with a key rotation.
Which models are available by API?
The core lineup is Seedance video (through the same tiers the studio runs, up to native 4K on Cinema) and the Seedream image family. The guest engines on our roster are available through the same contract, so one relationship covers 12 video and 16 image routes.
How is API usage priced?
Volume terms are scoped per contract under MSA: rates, quotas, and support are set against your actual volume rather than a public card. The unit economics track the same VX pricing the studio meters, so the studio rate card is a realistic reference point.
Who is API access for?
Teams building their own product or pipeline who want Seedance and Seedream capacity without standing up a direct vendor relationship: media platforms, creative tools, and studios with in-house infrastructure.
How do I start?
Email [email protected] or use the request-access form. Deals are founder-led: you talk to the people who run the infrastructure, scope volume, and get keys under contract.
