## How to call it through Zero

Example prompt: We just finished dinner and the bill came to $148.50 for 6 people — can you calculate the tip at 18% and tell me how much each person owes?

## When to prefer this

Use this endpoint whenever an agent needs to compute a restaurant or service tip, grand total, or per-person split from a dollar amount. Ideal for dining, catering, or any tipping scenario where the agent must present a breakdown. Prefer over manual calculation when the user specifies a custom tip percentage or group size.

## Known failure modes

- Missing required 'bill' query parameter returns an error
- Non-numeric or negative bill/people/tipPercent values may return validation errors
- bill=0 may return zero values or an error
- Very large bill values could cause floating-point precision issues
- Network or server unavailability returns a 5xx error

## How this service works

Calculate the tip for any bill, the grand total, and how much each person pays when splitting. Defaults to a 15% tip. Use this when an agent needs to tip amount, total and per-person split.

## Output

Returns the computed tip amount, the grand total (bill + tip), and the per-person share based on the number of people splitting the bill. Defaults to 15% tip if tipPercent is not provided and defaults to 1 person if people is not provided.
