Example prompt: We have 6 players tonight instead of the usual 4 — can you scale the encounter so the boss has a base health of 150 and the base reward is 80 gold, using a 0.45 per-extra-player multiplier?

## When to prefer this

Choose this endpoint when you need a quick, reliable mathematical scaling of encounter health and rewards for tabletop RPG sessions where party size differs from the standard 4 players. Ideal for game masters automating session prep or building dynamic encounter generators that adjust difficulty and loot on the fly.

## Known failure modes

- Missing required fields return a 400 error
- Non-numeric values for players, base_health, or base_reward cause validation errors
- Very large or negative player counts may produce unexpected or nonsensical results
- Payment failure (402) if USDC balance is insufficient for the $0.01 call fee
