Seedance 2.5 API — Live on FAL, Integrated Here
Public API since August 2026. ImagineToVideo runs it in production.
The Seedance 2.5 API is live: FAL serves text-to-video, image-to-video and reference-to-video endpoints with public schemas and published token pricing — and ImagineToVideo runs 2.5 on it in production. This page covers the API facts for developers, and the no-code path if you'd rather skip the keys.
Seedance 2.5 API — Verified Facts for Developers
API Status: Live on FAL
Three production endpoints — text-to-video, image-to-video and reference-to-video — with public schemas: 480p/720p, durations from 4 to 30 seconds, synchronized audio with lip-synced dialogue, and seed support.
Pricing: Published, Token-Based
FAL bills $0.0214 per 1,000 tokens (tokens = height × width × seconds × 24 / 1024) — roughly $0.47/s at 720p and $0.22/s at 480p with audio. Reference runs that include video inputs are billed at a 0.6× multiplier. ByteDance's own Volcano Ark rate card remains separate.
Reference Inputs at API Level
The reference-to-video endpoint accepts image, video and audio reference arrays — up to 50 inputs combined — for multimodal composition, video editing and extension. ImagineToVideo's integration exposes 9 reference images + 9 reference videos (1.8–30s each, 30s combined); the official 30-image budget and audio references stay on our roadmap.
Or Skip the API Entirely
ImagineToVideo runs Seedance 2.5 in the browser with credits instead of API keys — it is our default model. Validate prompts and reference setups visually before you commit engineering time.
What Developers Are Building — And On What
Content Pipelines
Batch-generate short clips with audio from prompt queues against FAL's 2.5 endpoints — or validate the pipeline visually here first.
Reference-Conditioned Generation
Products, characters or styles held consistent via reference images and video — 9 images + 9 videos on ImagineToVideo today, up to 50 combined inputs at the raw API.
Footage Transformation
Footage transformation through reference-to-video: restyle, edit or extend existing clips, billed at the discounted video-reference rate.
Prompt R&D Before Code
Validate prompts, references and durations in the browser, then encode the winning setup into your API calls.
How to Build on Seedance 2.5
API keys or credits — same model either way
Pick Your Access Path
For code: FAL's Seedance 2.5 endpoints with public schemas and token pricing. For no-code: the ImagineToVideo generator, where 2.5 is the default model with credit-based billing.
Design Around the Real Schema
Key parameters: resolution 480p/720p, duration 4–30 seconds (or auto), six aspect ratios, generate_audio, seed — plus quoted dialogue in the prompt for lip-sync. No 1080p tier exists at launch.
Budget with the Token Formula
Cost scales with pixels × seconds: a 30-second 720p clip runs about $14 at FAL list price, a 480p draft under half that. Reference runs with video inputs get the 0.6× multiplier but count input video duration in tokens.
Prototype Visually First
Test prompts, reference sets and durations in the ImagineToVideo generator, then encode the winning setup into your API calls — same model, same endpoints underneath.
Seedance 2.5 API FAQ
Is there a Seedance 2.5 API?
Yes. FAL serves Seedance 2.5 in production with three endpoints — text-to-video, image-to-video and reference-to-video — public schemas, and published token-based pricing. ImagineToVideo's own Seedance 2.5 integration runs on it.
What about ByteDance's official Volcano Ark API?
ByteDance has said API service is coming to Volcano Ark; hosted access via FAL is what shipped first and is what production apps (including ImagineToVideo) run today. If Ark publishes its own rate card and endpoints, that becomes a second access path.
How much does the Seedance 2.5 API cost?
FAL's published rate is $0.0214 per 1,000 tokens, where tokens = height × width × duration × 24 / 1024. In practice that is roughly $0.47 per second at 720p and $0.22 at 480p with audio; reference runs including video inputs are billed at 0.6× but count input video duration.
Is there a Seedance API I can use in production today?
Yes — Seedance 2.0 remains served by FAL and Replicate with public schemas, and it still holds one advantage over 2.5: a 1080p output tier. Both generations run side by side on ImagineToVideo.
What does the Seedance 2.5 API support?
Verified from the live schemas: 4–30 second single-pass generation with synchronized audio, lip-synced dialogue via quoted lines, 480p/720p output, six aspect ratios, first/last-frame image control, and reference arrays for images, video and audio (up to 50 combined). Frame rate is not specified in the schema.
Does ImagineToVideo offer Seedance 2.5?
Yes — live since August 7, 2026 and priced in credits. Seedance 2.5 runs start at 40 credits, while the $0.99 Starter Pack for new accounts holds 30 credits, so a plan is needed to generate with 2.5 itself.
Build on Seedance 2.5 Today
The 2.5 API is live on FAL and runs on ImagineToVideo with credit-based pricing. New accounts can try the platform with the $0.99 Starter Pack.
