Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 magent-bars-score-lookup-72c35f32
```

Example prompt: The patient is extremely and continuously active but doesn't require restraint — can you look up the BARS score and label for that level using the Swift 2002 scale? That should be a 6.

## When to prefer this

Use this endpoint when you need a standardized, stable label for a caller-assigned Swift 2002 BARS integer within an automated or agentic clinical documentation workflow. Prefer it over RASS-based endpoints when the assessment protocol specifically calls for the Behavioural Activity Rating Scale. Not a substitute for direct clinical observation or diagnosis.

## Known failure modes

- Input integer outside 1–7 range returns an error or unexpected result
- Non-integer input (e.g. decimal or string) may fail schema validation
- Missing required 'bars' query parameter results in a request error
- Payment failure (x402 protocol) prevents response

## How this service works

Swift 2002 Behavioural Activity Rating Scale (BARS): caller-assigned integer 1-7 (difficult or unable to rouse; asleep but responds normally to verbal or physical contact; drowsy, appears sedated; quiet and awake, normal activity; signs of overt physical or verbal activity, calms with instructions; extremely or continuously active, not requiring restraint; violent, requires restraint). Returns score, max 7, and a stable label. Not RASS and not a diagnosis. magent does not observe the patient.

## Output

Returns the BARS integer score as provided, the maximum possible BARS score (7), and a stable clinical label corresponding to the input integer (e.g. 'quiet and awake, normal level of activity' for a score of 4). No diagnosis is generated; magent does not observe the patient.
