AGENT 模式 / SEEDANCE 2.5 API

在 agent 写代码前,先给它正确的上下文。

本页面面向 Cursor、Claude Code、Codex、ChatGPT 等替人类接入 Seedance 2.5 API 的 agent。复制指令块,让 agent 读取机器文件,等代码就绪后再创建 provider Key。

01 / 上下文先复制这个

You are helping me integrate the Seedance 2.5 API.

Primary context: https://seedance25api.io/llms-full.txt
Integration schema: https://seedance25api.io/openapi.json

Rules:
- Do not invent or hardcode an API key.
- The official Seedance 2.5 API and EvoLink route are live; route status is confirmed.
- Ask me to create EVOLINK_API_KEY before the first live call: https://evolink.ai/dashboard/keys?utm_source=seedance25api.io&utm_medium=referral&utm_campaign=agent&utm_content=agent-prompt
- Choose seedance-2.5-text-to-video, seedance-2.5-image-to-video, or seedance-2.5-reference-to-video for the matching workflow.
- Use 4–30 seconds and 480p/720p; do not advertise 4K as an EvoLink API tier.
- For R2V, preserve the documented split of up to 30 images, 10 videos, and 10 audio files.
- Poll GET /v1/tasks/{task_id} for task status.
- Read the current EvoLink console price before scaled traffic; never substitute upstream official pricing.
- Keep the model configurable and retain Seedance 2.0 only as rollback.

为什么这样有效

agent 拿到稳定的上下文 URL、schema、Key 边界,以及明确的 provider 交接。它可以在不假装已有凭证的前提下准备好代码。

创建 API Key

02 / 机器文件AGENT 应读取什么

/llms.txt给 LLM 和搜索 agent 的简短索引。 /llms-full.txt完整上下文:事实、状态、schema、价格说明、交接。 /agent.md给 coding agent 的 Markdown 清单。 /openapi.json给 API 客户端和代码生成的请求契约。

03 / 事实状态感知的接入

Confirmed

Live on EvoLink · API key access available

The upstream official API and EvoLink integration are live for the August 7 publication. Use the three workflow-specific EvoLink model IDs and verify the current price shown in the EvoLink console before production traffic.

Confirmed

Text to video

seedance-2.5-text-to-video

Live EvoLink model ID for prompt-only text-to-video requests.

Confirmed

Image to video

seedance-2.5-image-to-video

Live EvoLink model ID for first-frame or first/last-frame image-to-video requests.

Confirmed

Reference to video

seedance-2.5-reference-to-video

Live EvoLink model ID for multimodal reference-to-video, editing, and extension workflows.

Confirmed

Launch 限制

4–30 seconds · 480p and 720p

使用已文档化的 4–30 秒与 480p/720p launch 值,保持可配置,并用一次短时真实调用确认账号级上限。

04 / AGENT 清单正式调用前

Do not invent or hardcode an API key.
The official API and the EvoLink route are live for this publication; keep their sources and pricing distinct.
Use the workflow-specific Seedance 2.5 model ID and keep Seedance 2.0 only as a rollback.
Ask the human to create EVOLINK_API_KEY before a live call.
Build behind a configurable model parameter.
Do not present upstream provider token rates as EvoLink route prices.
Use 4–30 seconds, 480p/720p, and the documented per-type reference limits; never advertise 4K as an API tier.
Poll GET /v1/tasks/{task_id} for the EvoLink asynchronous task flow.
Read the current EvoLink console price before production traffic; do not present upstream official pricing as an EvoLink quote.
