## Features

- Simple, intuitive API for creating and verifying crypto payment invoices
- Support for **60+ fiat currencies** with automatic stablecoin conversion
- Built-in retry logic with exponential backoff
- Pydantic-powered request/response validation
- Comprehensive error handling with typed exceptions
- Full type annotations for IDE autocompletion and static analysis
- Environment variable support for API key management

## Installation

```bash
pip install nodela
```

**Requirements:** Python 3.9+

## Quick Start

### 1. Get your API key

Sign up at [nodela.co](https://nodela.co) and retrieve your API key from the dashboard.

### 2. Initialize the client

```python
from nodela import NodelaClient

# Pass the key directly
client = NodelaClient(api_key="your_api_key")

# Or set the NODELA_API_KEY environment variable and omit the argument
client = NodelaClient()
```

### 3. Create a payment invoice

```python
from nodela import NodelaClient, CreateInvoiceParams

client = NodelaClient(api_key="your_api_key")

params = CreateInvoiceParams(
    amount=50.00,
    currency="USD",
    success_url="https://yoursite.com/success",
    cancel_url="https://yoursite.com/cancel",
    webhook_url="https://yoursite.com/webhooks/nodela",
    reference="ORDER-123",
    title="Premium Plan",
    description="Monthly subscription",
    customer={
        "email": "customer@example.com",
        "name": "Jane Doe",
    },
)

response = client.invoices.create(params)

if response.success:
    print(f"Checkout URL: {response.data.checkout_url}")
    print(f"Invoice ID:   {response.data.invoice_id}")
```

### 4. Verify a payment

```python
result = client.invoices.verify("inv_abc123")

if result.success and result.data.paid:
    print(f"Payment confirmed! Status: {result.data.status}")
    if result.data.payment:
        print(f"Tx hash: {result.data.payment.tx_hash}")
```

### 5. List transactions

```python
response = client.transactions.list(page=1, limit=20)

for txn in response.data.transactions:
    print(f"{txn.invoice_id} | {txn.original_amount} {txn.original_currency} | {txn.status}")

print(f"Page {response.data.pagination.page} of {response.data.pagination.total_pages}")
```

## Configuration

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `api_key` | `str` | `None` | Your Nodela API key. Falls back to `NODELA_API_KEY` env var. |
| `timeout` | `int` | `30` | Request timeout in seconds. |
| `max_retries` | `int` | `3` | Maximum retry attempts for failed requests. |

```python
client = NodelaClient(
    api_key="your_api_key",
    timeout=60,
    max_retries=5,
)
```

## Error Handling

The SDK raises typed exceptions so you can handle specific failure modes:

```python
from nodela import (
    NodelaClient,
    CreateInvoiceParams,
    NodelaError,
    AuthenticationError,
    ValidationError,
    RateLimitError,
    NotFoundError,
    ServerError,
    NetworkError,
)

client = NodelaClient(api_key="your_api_key")

try:
    response = client.invoices.create(
        CreateInvoiceParams(amount=100, currency="USD")
    )
except AuthenticationError:
    print("Invalid API key")
except ValidationError as e:
    print(f"Bad request: {e}")
except RateLimitError:
    print("Too many requests - slow down")
except NotFoundError:
    print("Resource not found")
except ServerError:
    print("Nodela server error - try again later")
except NetworkError:
    print("Network issue - check your connection")
except NodelaError as e:
    print(f"Unexpected API error ({e.status_code}): {e}")
```

| Exception | HTTP Status | When |
|-----------|-------------|------|
| `AuthenticationError` | 401 | Invalid or missing API key |
| `ValidationError` | 400 / 422 | Invalid request parameters |
| `NotFoundError` | 404 | Invoice or resource not found |
| `RateLimitError` | 429 | Too many requests |
| `ServerError` | 5xx | Nodela server error |
| `NetworkError` | N/A | Connection timeout or failure |

All exceptions inherit from `NodelaError`, which exposes `status_code` and `response` attributes.

## Supported Currencies
