Identify and exploit API operations that create business value/cost and test whether they can be automated, repeated, or abused beyond their intended human workflow limits.

## Preconditions

- Understanding of what the business does and what operations cost money or resources

## Attack Surface Signals
- Coupon/discount/promo code endpoints
- Referral/affiliate/invite endpoints
- OTP/password-reset/SMS/email sending endpoints
- Account creation, free trial, or signup endpoints
