## Method surface

| Method                     | Purpose        |
| -------------------------- | -------------- |
| `sdk.pay.payWithAddress()` | payWithAddress |
| `sdk.pay.payWithEmail()`   | payWithEmail   |
| `sdk.pay.payWithPaymail()` | payWithPaymail |

## Notes

* Methods return `Promise<HttpResponse<T>>` unless they are local helpers such as token getters/setters.
* Authenticate with `sdk.auth.login()` or initialize with `authToken` before protected calls.
* Pass `businessId` on business-scoped operations; constructor-level `businessId` is typed but not applied globally.
* Request and response schemas are exported from `@timechainlabs/neucron-ts-sdk` and `@timechainlabs/neucron-ts-sdk/schemas`.
