## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-final-exam-score-calculator-844a742f
```

Example prompt: I currently have a 74% in my class, I need at least an 80% to keep my scholarship, and the final is worth 35% of my grade — what score do I need on the final exam?

## When to prefer this

Use this endpoint when a student or academic planning agent needs a precise, formula-backed calculation of the minimum final exam score required to reach a target grade. It is purpose-built for this single computation with clean JSON output including feasibility checking, making it preferable to generic math tools or LLM-estimated grade calculations when accuracy and structured output matter.

## Known failure modes

- Missing required query parameters (current_score, target_score, or final_weight_percent) returns an error
- final_weight_percent of 0 or greater than 100 is rejected as invalid
- Non-numeric string values for score fields may cause calculation errors
- If target is mathematically impossible even with 100 on the final, possible_with_100 returns false
- Payment failure or insufficient USDC balance returns 402 before any calculation is performed

## How this service works

Final exam score-needed calculator from current score, target and exam weight

## Output

Returns a JSON object with the computed required final exam score, the input values (current score, target score, final weight), a boolean indicating whether the target is achievable with a perfect 100 score, the formula used in the calculation, and a scope note explaining what the calculation covers and its limitations.
