# McEntire 2025 FACE DROPS Score — Lyme Disease Facial Palsy vs Bell Palsy

> McEntire 2025 FACE DROPS Score — Lyme Disease Facial Palsy vs Bell Palsy 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 McEntire 2025 FACE DROPS clinical decision score to differentiate acute Lyme disease-associated facial palsy from Bell palsy based on seven caller-assigned symptom flags.

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 mcentire-2025-face-drops-score-lyme-disease-facial-palsy-vs-bell-palsy-98a721dd
```

Example prompt: Run the FACE DROPS score for a patient with acute facial palsy — they have fever (yes), arthralgia/myalgia (yes), headache (yes), exhaustion (yes), dermatomal or radicular pattern (no), otalgia or postauricular pain (no), and stiff neck (yes). Does this favor Lyme disease facial palsy or Bell palsy?

## When to prefer this

Use this endpoint when a clinician or agent has already assessed the seven FACE DROPS symptom flags for a patient with acute facial palsy and needs the McEntire 2025 arithmetic score and categorical interpretation (Bell palsy vs Lyme facial palsy vs indeterminate). This is not a Lyme diagnostic test, serology orderer, or stroke screening tool — choose a different endpoint or service for those needs.

## Known failure modes

- Missing any of the seven required boolean query parameters returns a validation error
- Passing non-boolean values for symptom flags causes a schema rejection
- Network or payment authorization failure (x402) returns a 402 Payment Required response
- Score is indeterminate (5–6) — no definitive guidance returned, caller must use clinical judgment

## How this service works

McEntire 2025 FACE DROPS: seven caller-assigned flags for acute Lyme disease-associated facial palsy versus Bell palsy. Fever +8, aches (arthralgia/myalgia) +6, cephalalgia +3, exhaustion +4, dermatomal or radicular pattern +4, otalgia or postauricular pain −1, stiff neck +3. Score −1 to 28. Scores ≤4 favor Bell palsy; ≥7 favor LDFP; 5–6 indeterminate. Not a Lyme test, diagnosis, serology order, or stroke FACE-DROPS mimic score. magent does not examine the face.

## Output

Returns the integer FACE DROPS total score (range −1 to 28) and an interpretation: scores ≤4 favor Bell palsy, ≥7 favor Lyme disease-associated facial palsy (LDFP), and 5–6 are indeterminate. Does not perform examination, order serology, diagnose, or evaluate for stroke mimics.
