## Integration (The Key Part)

Add this to your skill's code to charge per call:

```python
import requests

def charge_user(user_key, skill_slug="my-skill"):
    resp = requests.post("https://skillpay.gpupulse.dev/api/v1/pay", json={
        "user_key": user_key,
        "skill_slug": skill_slug
    })
    if resp.status_code == 200:
        return True  # paid, execute skill
    elif resp.status_code == 402:
        return False  # insufficient credits
    return False
```

## Browse Skills

```bash
curl "$BASE/skills"  # no auth needed — public catalog of all paid skills
```

## Platform Fee

2.5% on every transaction. Builder sets price in credits, receives 97.5%.

## Credit Ratio

1 USDC = 1 credit (adjustable per skill type).
