🔀 Per-Request API Key Override

Every method supports a per-request API key override — useful for multi-tenant apps:

client = AllRatesToday(api_key="default_key")

# Override for a specific request
data = client.latest(api_key="other_users_key")
result = client.convert("USD", "EUR", 100, api_key="tenant_key")
symbols = client.symbols(api_key="another_key")

---

🛡️ Error Handling

All errors are raised as AllRatesTodayError with an optional HTTP status code:

from allratestoday import AllRatesToday, AllRatesTodayError

client = AllRatesToday(api_key="YOUR_API_KEY")

try:
    rate = client.get_rate("USD", "INVALID")
except AllRatesTodayError as e:
    print(e)        # "Currency not found"
    print(e.status)  # 404

Status	Meaning
—	Missing API key (raised before request)
401	Invalid API key
404	Currency code not found
