## 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 midas-score-calculator-magent-3bff5fe7
```

Example prompt: Calculate the MIDAS score for a patient who missed 8 days of paid work, had 5 days of reduced work productivity, missed 3 days of household work, had 4 days of reduced household productivity, and missed 2 days of family or social activities in the last 3 months.

## When to prefer this

Use this endpoint when you need a standardized, validated MIDAS disability score and grade from five pre-collected 3-month activity-impact day counts. Prefer it over manual calculation to avoid arithmetic errors, and when you need a structured grade label (I–IV) for clinical documentation, research, or triage workflows. Not appropriate for diagnosing migraine, prescribing triptans or prophylaxis, or computing psychiatric screening scores like GAD-7 or PHQ-9.

## Known failure modes

- Missing any of the five required query parameters returns a validation error
- Values outside the 0–90 integer range per item may be rejected or produce unexpected scores
- Double-counted days between missed and reduced categories are not de-duplicated by the API — caller must handle this
- Non-integer inputs will fail schema validation
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Stewart 1999 MIDAS from five caller-assigned 3-month day counts: missed paid work/school, work/school ≥50% reduced, missed household work, household ≥50% reduced, missed family/social/leisure. Each 0-90; total 0-450. magent does not include questions A or B and does not assign or de-duplicate days. Grades I 0-5 little/minimal, II 6-10 mild, III 11-20 moderate, IV ≥21 severe. Not a migraine diagnosis, not a triptan/prophylaxis order, not GAD-7 or PHQ-9.

## Output

Returns the MIDAS total score (integer, 0–450, sum of the five input day counts) and the corresponding disability grade: Grade I (0–5, little/minimal), Grade II (6–10, mild), Grade III (11–20, moderate), or Grade IV (≥21, severe). Does not diagnose migraine or recommend treatment.
