## Cost Analysis

### Fluxis API

Fluxis pricing depends on your merchant agreement (volume, networks, and support level). Contact [support@fluxis.us](mailto:support@fluxis.us) for staging and production credentials.

**Typical API integration cost drivers:** payment service fees (configurable per organization/account), blockchain gas for settlements, and your own engineering time for checkout + webhook handling.

## When to Choose Each Option

### Choose Fluxis API When:

- ✅ You want to get to market quickly
- ✅ You need enterprise-grade security
- ✅ You want to focus on your core product
- ✅ You need reliable, scalable infrastructure
- ✅ You want expert support and documentation
- ✅ You're building a production application

### Choose Self-Implementation When:

- ❌ You need complete control over the implementation
- ❌ You have specific compliance requirements not met by Fluxis
- ❌ You have unlimited development resources and time
- ❌ You're building a research or educational project
- ❌ You need to modify the NASPIP protocol itself

## Migration Path

If you've already started self-implementation, you can easily migrate to Fluxis API:

```bash
# Replace your custom implementation with Fluxis API calls
# Old: Custom NASPIP signing
const customToken = await signNASPIP(paymentData, privateKey);

# New: Fluxis API
const { data: auth } = await (await fetch('https://api.fluxis.us/v1/auth/token', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ api_key: 'YOUR_API_KEY', api_secret: 'YOUR_API_SECRET' })
})).json();

const fluxisToken = await fetch('https://api.fluxis.us/v1/naspip/create', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${auth.token}`,
    'x-fluxis-api-key': 'YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ payment: paymentData })
});
```

## What Fluxis API includes today

| Capability | Fluxis API | Self-implementation |
|------------|------------|------------------------|
| Payment requests via POS | `POST /v1/pos/:posID/payment-request` | Build + operate |
| Webhooks | Account-level `POST /v1/account/{accountID}/webhook` | Build delivery + retries |
| Reconciliation | `GET /v1/transactions` (paginated) | Build indexing |
| NASPIP URL tokens | `POST /v1/naspip/read` resolves embedded URLs | Implement fetch + validation |
| Refunds | `POST /v1/refunds/payment-request/{id}` | Build settlement logic |

See the [API Integration Guide](/docs/developers/tutorials/api-integration-guide) for the supported production flow.

## Conclusion

For 99% of applications, **Fluxis API is the clear choice**. It provides:

- **10x faster time to market**
- **100x lower development cost**
- **Enterprise-grade security out of the box**
- **Zero maintenance burden**
- **Expert support and documentation**

The only reason to self-implement NASPIP is if you have very specific requirements that Fluxis doesn't meet, or if you're contributing to the protocol itself.
