# ADAPT 2-Hour Accelerated Chest Pain Diagnostic Protocol Calculator

> ADAPT 2-Hour Accelerated Chest Pain Diagnostic Protocol Calculator 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).

Applies the 2012 ADAPT accelerated diagnostic protocol to determine low-risk status for emergency chest pain patients using caller-supplied TIMI score, ECG finding, and two serial troponin 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 adapt-2-hour-accelerated-chest-pain-diagnostic-protocol-calculator-f8e3bee0
```

Example prompt: This patient has a TIMI score of 0, no new ischemic ECG changes, a negative 0-hour troponin, and a negative 2-hour troponin — run the ADAPT protocol and tell me if they qualify as low risk.

## When to prefer this

Choose this endpoint when you need to programmatically apply the validated Than 2012 ADAPT 2-hour accelerated diagnostic protocol in an emergency department workflow and you have already determined the TIMI UA/NSTEMI score, ECG findings, and two timed serial troponin results independently. Prefer this over HEART Pathway calculators when the clinical protocol specifically calls for ADAPT. Not appropriate if you lack a true 2-hour troponin (vs 3-hour), or if you need a different ED chest pain pathway such as HEART or EDACS.

## Known failure modes

- Missing required query parameters (timi_score, new_ischemic_ecg, troponin_0_elevated, troponin_2h_elevated) results in a validation error
- timi_score outside integer range 0-7 may be rejected
- Using a 3-hour troponin result instead of the required 2-hour troponin produces a protocol-invalid result
- Payment failure or missing x402 header returns a 402 response
- Caller incorrectly assigns TIMI items or reads ECG — the API accepts caller inputs as-is and cannot detect upstream clinical errors

## How this service works

Than 2012 ADAPT 2-hour accelerated diagnostic protocol for emergency chest pain. low_risk is true only when the caller-assigned TIMI UA/NSTEMI score is 0, new ischemic ECG changes are absent, and both 0-hour and 2-hour (not 3-hour) troponin flags are not elevated. magent does not assign TIMI items, read an ECG, or assay troponin. Not HEART Pathway. Not a discharge order, ACS diagnosis, or stress-test order. Not a medical device.

## Output

Returns a structured object indicating whether the patient meets ADAPT low-risk (ADP-negative) criteria. low_risk is true only when TIMI score is 0, new_ischemic_ecg is false, troponin_0_elevated is false, and troponin_2h_elevated is false; any single positive flag yields false. Does not provide a discharge order, ACS diagnosis, or stress-test recommendation.
