NezhaGate agent skills

Agent Skills that let coding agents (Claude Code, Codex, Cursor and other skill-aware agents) use the NezhaGate API directly: ask in plain words, and the agent picks the model, sends your files, waits for the job and saves the result.

中文说明

Made with this skill in one request: seedance-2.5, 8 s, 720P, one reference image, generated soundtrack. Watch the clip · storyboard

Skill	What it does
nezhagate-seedance	Text-to-video and video from reference images, videos and audio with ByteDance Seedance 2.5 / 2.0, including the per-clip Seedance 2.0 Clip and Seedance 2.5 30s, native soundtrack. Includes a zero-dependency Python helper that lists the models on sale with live prices, checks the request before you pay, then submits, waits and downloads.

Install

One line, from our site:

npx skills add https://nezhagate.com

or from this repository:

npx skills add gaoorange/nezhagate-skills

Manual install: copy skills/nezhagate-seedance/ into your agent's skills folder, for example ~/.claude/skills/nezhagate-seedance/ for Claude Code or ~/.codex/skills/nezhagate-seedance/ for Codex.

Set your key

Create a key at https://nezhagate.com/keys, then make it available to the agent:

export NEZHAGATE_API_KEY=your_key            # macOS / Linux

$env:NEZHAGATE_API_KEY = "your_key"           # Windows PowerShell (current window)
setx NEZHAGATE_API_KEY "your_key"             # Windows, for windows opened later

Start the agent from a shell where the variable is set. The skill never needs the key in your project files.

Try it

Use the nezhagate-seedance skill: make an 8-second 16:9 clip with seedance-2.5 of the woman in ./hero.png
turning to the camera on a rooftop at golden hour, slow dolly in, and save it to ./out/rooftop.mp4.

Or run the helper yourself:

python skills/nezhagate-seedance/scripts/seedance.py --models      # models on sale, live prices
python skills/nezhagate-seedance/scripts/seedance.py --model seedance-2.5 --image ./hero.png \
  --prompt "The woman from @Image1 turns to the camera on a rooftop at golden hour, slow dolly in" \
  --duration 8 --ratio 16:9 --dry-run                              # check the request, submit nothing
python skills/nezhagate-seedance/scripts/seedance.py --model seedance-2.5 --image ./hero.png \
  --prompt "The woman from @Image1 turns to the camera on a rooftop at golden hour, slow dolly in" \
  --duration 8 --ratio 16:9 --out ./out/rooftop.mp4                # submit, wait, download

For a long or multi-line prompt, put it in a UTF-8 file and pass --prompt-file prompt.txt instead of --prompt.

The prompt behind the demo clip:

Golden-hour rooftop in an old Chinese city. The young woman from @Image1, in a cream trench coat, turns from the railing toward the camera; the wind lifts her hair, she hesitates, then breaks into a small relieved smile as distant temple bells ring. Slow dolly-in from medium shot to close-up, shallow depth of field, warm rim light, film grain, soft strings over the city hum.

How NezhaGate runs your jobs

• Failed renders cost nothing: the amount is reserved at submit and refunded in full if a render fails.
• Your content stays yours: prompts and outputs are never used for training; the text of your calls is deleted after 30 days and generated files after 60 days (privacy policy).
• Live status: real success rates are published at https://nezhagate.com/status.

Some Seedance models bill per second and others per clip, in NezhaGate credits. Current prices: --models or https://nezhagate.com/en/pricing.
