Rate and serviceability checks

The repository exposes two related methods:

• checkServiceability(params)
• calculateRates(params)

Both call Shiprocket's courier serviceability endpoint in the current implementation.

Example

const serviceability = await sdk.checkServiceability({
  pickup_postcode: "400001",
  delivery_postcode: "110001",
  weight: 0.5,
  cod: 0,
});

console.log(serviceability);

Both methods accept pickup_postcode, delivery_postcode, weight, and an optional cod flag (calculateRates() also accepts order_id).

Response shape

The SDK returns the raw Shiprocket payload typed as unknown. Courier options and charges are typically under data.available_courier_companies; inspect that array to compare delivery estimates and rates.

Notes

• There is no built-in cheapest-provider comparison logic
• There is no multi-provider rate ranking layer
