Calculates shipping cost (in RUB) and delivery time range (min/max days) for Russian Post between two Russian postal codes

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saymon-ru-data-api-f0ffc03c
```

Example prompt: How much will it cost to send a 1 kg parcel via Russian Post from postal index 101000 (Moscow) to 190000 (Saint Petersburg), and how many days will it take?

## When to prefer this

Use this endpoint when you need both the shipping cost and the delivery time range for Russian Post in a single call. Prefer this over the sibling 'delivery days only' endpoint when you need pricing information as well. Best suited for e-commerce checkout flows, logistics cost calculators, or any automation that needs to quote Почта России tariffs programmatically between two Russian postal codes.

## Known failure modes

- Invalid or non-existent postal index returns an error or empty response
- Missing required fields (from_index, to_index) results in validation error
- Unsupported mail_type or mail_category combination may return an error
- Network timeout or upstream Russian Post API unavailability
- Weight outside acceptable range may cause rejection
