# magent PSS-3 Suicide Risk Screener

> magent PSS-3 Suicide Risk Screener is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the Boudreaux 2015 PSS-3 suicide risk screen result (positive/negative) from four caller-assigned clinical flags, following the ED-SAFE protocol

## 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-pss-3-suicide-risk-screener-2d54989a
```

Example prompt: Run the PSS-3 suicide screen on this patient: they reported depressed mood over the past 2 weeks (true), they have active suicidal ideation in the past 2 weeks (true), they have no lifetime suicide attempt (false), and attempt within 6 months is false — tell me if they screen positive.

## When to prefer this

Use this endpoint when you need a fast, protocol-compliant PSS-3 (ED-SAFE / Boudreaux 2015/2016) suicide risk screen computation from four discrete caller-assigned flags — it is not C-SSRS, not a full clinical interview, and not a diagnosis. Prefer this over general-purpose LLM reasoning when you need an auditable, rule-based algorithm that faithfully implements the published PSS-3 screening logic without hallucination risk.

## Known failure modes

- Missing required query parameters (depressed_mood, ideation_2_weeks, lifetime_attempt, attempt_within_6_months) returns a 400 or validation error
- attempt_within_6_months set to true when lifetime_attempt is false — logically invalid combination per protocol
- Non-boolean values passed for flag parameters cause schema validation failure
- Network or upstream API errors return 5xx responses
- Payment/x402 authorization failure if USDC payment not provided

## How this service works

Boudreaux 2015 PSS-3 from four caller-assigned flags: depressed_mood (2-week segue, not in the screen), ideation_2_weeks, lifetime_attempt, and attempt_within_6_months. screen_positive if 2-week ideation or a lifetime attempt within 6 months (ED-SAFE / Boudreaux 2016 Am J Prev Med). Depression is not factored into screening results. magent does not interview the patient. Not a diagnosis. Not C-SSRS. Not a medical device.

## Output

Returns a structured JSON object indicating whether the patient screens positive for suicide risk (screen_positive boolean) based on the ED-SAFE / Boudreaux 2015 PSS-3 algorithm: positive if ideation_2_weeks is true OR if both lifetime_attempt and attempt_within_6_months are true. Depression flag is not factored into screen_positive. Not a diagnosis, not C-SSRS, not a medical device.
