## Use this skill

puras runs this skill on its own backend — you send inputs and get the result back. Three ways to call, fastest first:

### 1. MCP server — recommended for coding agents, no API key

Connect the puras MCP server; auth is OAuth in the browser on first call, so there is nothing to paste.

```bash
claude mcp add --transport http puras https://mcp.puras.co/mcp
```

Any MCP client works — point it at `https://mcp.puras.co/mcp` (HTTP transport). Then ask the agent to run `end-card-generator` from skillpack `puras/game-ad-studio` with your inputs.

### 2. CLI / Python SDK — `pip install puras`

```bash
pip install puras
puras login            # or set PURAS_API_KEY
puras run puras/game-ad-studio/end-card-generator -i key=value
```

From Python:

```python
import puras

client = puras.Client()   # PURAS_API_KEY from env
result = client.run("puras/game-ad-studio/end-card-generator", {"logo":"https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_logo.webp","style":"playful","cta_text":"Play Free","headline":"Build a village!","references":["https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_ss1.webp","https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_ss2.webp","https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_ss3.webp"],"aspect_ratio":"9:16"})
```

### 3. HTTP API

`wait=true` blocks until the run reaches a terminal status and returns the result inline.

```bash
curl -X POST "https://api.puras.co/v1/jobs?skillpack=puras/game-ad-studio&wait=true" \
  -H "Authorization: Bearer $PURAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"skill":"end-card-generator","inputs":{"logo":"https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_logo.webp","style":"playful","cta_text":"Play Free","headline":"Build a village!","references":["https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_ss1.webp","https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_ss2.webp","https://uozfqcfhlhugotnevscg.supabase.co/storage/v1/object/public/puras-public-skills/coc_ss3.webp"],"aspect_ratio":"9:16"}}'
```

## Pricing

Runs are billed usage-based from your workspace credit balance — the cost of a job is the sum of the model token (and any media) usage it incurs. There is no per-call platform fee. The playground and the job result report the exact cost of each run.
