Steps
- /start. Show usage, an example calculation, and sharing and web calculator buttons.
- /calc 150. Use a whole number from 0 to 1000000, without commas or decimals. This is an estimated purchase cost, not a live quote or cash-out value. Telegram pack prices vary by region and platform.
- /paysupport. Confirm that the calculator is free and has no purchase or Pro tier.
Good to know
- Free calculator. No purchase or Pro tier.
- Inline calculation is implemented: type @MyHoldFolioBot 150 in a chat once inline mode is enabled by the owner in BotFather. Activation is still pending; use /calc or the web calculator now.
- The bot stores Telegram user details and start/action events. Calculator amounts are not stored; inline queries are processed in memory without database writes.
- The shared kit/stars-calc.ts sets USD_CENTS_PER_STAR = 2. Its provenance is intel/s453/payments/REPORT.md and the site’s existing 150 Stars ≈ $3 estimate. The bot and web calculator use the same arithmetic.

- Check the unit before entering an amount: the command expects a count of Telegram Stars, not a dollar amount or a coin symbol. For example, /calc 150 uses the digits after the command as the number of Stars. A decimal input such as /calc 1.5 is rejected rather than rounded. A comma-separated input such as /calc 1,000 is rejected too; write /calc 1000 instead. Zero is allowed, and amounts above 1000000 are rejected. If the input is invalid, the bot replies with the accepted format. This does not create a portfolio entry or make a purchase. The output is a calculation that you can compare with the price shown in Telegram. The web tool uses the same rate and upper limit, so switching from chat to the browser does not produce a different underlying estimate.
