## How to call it through Zero

```

Example prompt: Using the Schwab and England ADL scale, what is the score and functional label for a patient rated at 60% — they can do most chores but exceedingly slowly and with much effort?

## When to prefer this

Use this endpoint when you need to programmatically look up the standardized Schwab and England (1969) ADL scale label and score from a clinician-assigned percentage. Prefer this over manual lookup or LLM inference when you need a stable, authoritative label from the original scale for documentation, research, or clinical decision-support pipelines. Not a substitute for clinical observation — the caller must assign the ADL percent.

## Known failure modes

- Invalid adl_percent value not in {0,10,20,30,40,50,60,70,80,90,100} — likely returns 4xx error
- Missing required adl_percent query parameter — request fails with validation error
- Non-integer value supplied for adl_percent — schema validation failure
- Payment failure (x402) — endpoint requires $0.005 USDC per call; insufficient funds cause rejection

## How this service works

Schwab and England ADL (1969): caller-assigned integer 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 (completely independent; independent with some slowness; independent in most chores; not completely independent; some dependency; more dependent; very dependent; few chores with effort; nothing alone; totally dependent; vegetative). Returns score, max 100, and a stable label. 0% vegetative is scored. Not Hoehn and Yahr and not Karnofsky. magent does not observe the patient. Not a medical device.

## Output

Returns a numeric score (max 100), the caller-supplied ADL percent, and a stable descriptive label (e.g. 'more dependent, help with half, difficulty with everything') corresponding to the Schwab and England 1969 Activities of Daily Living scale level.
