## When to prefer this

Use this endpoint when you need a fast, authoritative computation of standard marketing or business profitability metrics (ROI %, ROAS, profit, profit margin) from just two inputs — cost and revenue — without doing the math manually or risking formula errors. Ideal for evaluating ad campaign performance, e-commerce margins, or any spend-vs-return analysis.

## Known failure modes

- Missing required fields (cost or revenue): returns validation error
- Zero cost value may cause division-by-zero error for ROI/ROAS calculations
- Non-numeric values in cost or revenue fields cause schema validation failure
- Negative revenue or cost values may produce unexpected or undefined results
- Payment failure (insufficient USDC balance) prevents call from completing

## How this service works

## Output

Returns ROI as a percentage, ROAS (revenue divided by cost), gross profit (revenue minus cost), and profit margin as a percentage — all derived from the provided revenue and cost values.
