# Birthday Celebration

> A vibrant birthday card template to celebrate someone special — includes their photo, name, and a heartfelt message.

This is a [Bannx](https://bannx.com) template. Render any of its **pages** to an image (PNG, SVG, WebP) or PDF through the Bannx Render API, and customize the output by passing **tweaks** (variable overrides).

## Template

- Template ID: `birthday`
- Category: occasion
- Pages: 1
- Open in browser: https://bannx.com/templates/birthday

## How to use

1. Pick a **page** below and note its **page ID**.
2. Call the Render API with that page ID. Override text, colors, and other values via the `tweaks` map (keys are the variable names listed below).
3. Authenticate with an API key (create one under **Settings → Space → Developers**) using the `Authorization: Bearer <token>` header. GET requests for this template require a token (or the space GET render secret `gt`).

## Quick demo (no API key)

AI agents and curious humans can render this **public** template with tweaks without an account. Mint a short-lived **demo token** (IP-throttled, ~1h TTL, max 5 per hour per IP) and pass it as `?demo=...` (or `Authorization: Bearer <token>`):

```bash
# 1. Mint a demo token (no auth required)
curl -s -X POST https://bannx.com/api/demo-token
# → { "token": "demo_…", "expiresAt": …, "quota": { … } }

# 2. Render with the token (public templates only)
curl -L "https://bannx.com/api/render/0MoRv_ZKK3DoYZtvef3WN?format=png&output=binary&demo=demo_…" --output demo.png
```

Demo tokens only work on public templates and don't consume any space's credits. For production usage, create an API key under **Settings → Space → Developers** instead.
