# NIRUDAK Dehydration Score Calculator (Barry 2021)

> NIRUDAK Dehydration Score Calculator (Barry 2021) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Calculates the Barry 2021 NIRUDAK integer dehydration severity score (0–13) for patients aged 5–120 years with acute diarrhea, classifying them into no, some, or severe dehydration bands.

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 nirudak-dehydration-score-calculator-barry-2021-ff1695a4
```

Example prompt: Calculate the NIRUDAK dehydration score for a 12-year-old male patient with acute diarrhea: eyes are sunken, radial pulse is decreased, respirations are deep, skin pinch is slow, and he has had between 1 and 10 vomiting episodes in the past 24 hours — tell me the score and whether it's none, some, or severe dehydration.

## When to prefer this

Choose this endpoint when you need to compute the specific Barry 2021 NIRUDAK dehydration score (not WHO IMCI/IMAI, not DHAKA, not PLOS logistic models) for a patient aged 5–120 years with acute diarrhea, using the seven Table 2 clinical variables. Use it for clinical decision support workflows where a structured, peer-referenced integer score and severity band are needed; note it does not examine the patient or order fluids.

## Known failure modes

- Missing required query parameter returns an error (e.g. omitting skin_pinch or age)
- Age outside 5–120 range may return a validation error
- Invalid enum value for sex, eye_level, radial_pulse, respirations, skin_pinch, or vomiting_episodes_24h returns an error
- Non-integer age value causes a schema validation failure
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Barry 2021 NIRUDAK Table 2 integer score (max 13) for patients 5–120 years with acute diarrhea: age, sex, eye_level, radial_pulse, respirations, skin_pinch (rapid/slow/very_slow), vomiting_episodes_24h. Bands 0-3 no, 4-6 some, 7-13 severe dehydration. Not WHO IMCI/IMAI. Not DHAKA. Not PLOS logistic models. magent does not examine the patient or order fluids. Not a medical device.

## Output

Returns a NIRUDAK integer score from 0 to 13 computed from the weighted Barry 2021 Table 2 criteria, along with the corresponding dehydration severity band: no dehydration (0–3), some dehydration (4–6), or severe dehydration (7–13).
