# HexSeedance

Minimal Elixir helpers for building tracked `aiseedance2.net` links and basic
integration utilities.

This package is intentionally small but functional: it gives Elixir projects a
simple way to generate canonical landing URLs, UTM-tagged campaign links,
referral links, embed links, and verify webhook signatures for AI Seedance.

Hex package page goal:

- show a clean package description
- expose `https://aiseedance2.net/` in the Hex `Links` section
- keep the package compliant by shipping real functionality

## Installation

Add `hex_seedance` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:hex_seedance, "~> 0.1.0"}
  ]
end
```

## Usage

```elixir
iex> HexSeedance.website_url()
"https://aiseedance2.net"

iex> HexSeedance.campaign_url("/pricing", source: "hex", medium: "package", campaign: "launch")
"https://aiseedance2.net/pricing?utm_campaign=launch&utm_medium=package&utm_source=hex"

iex> HexSeedance.referral_url("creator-42")
"https://aiseedance2.net?ref=creator-42"

iex> HexSeedance.generate_share_url("/gallery", ref: "creator-42", source: "hex")
"https://aiseedance2.net/gallery?ref=creator-42&utm_source=hex"

iex> HexSeedance.embed_url("demo-video", autoplay: true)
"https://aiseedance2.net/embed?asset=demo-video&autoplay=1"
```

Webhook example:

```elixir
payload = ~s({"event":"render.completed"})
signature = HexSeedance.sign_webhook(payload, "topsecret")

HexSeedance.verify_webhook_signature(payload, signature, "topsecret")
# true
```
