x402
HAPS (Harmless Acute Pancreatitis Score) 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).
Computes the HAPS (Lankisch 2009) harmless acute pancreatitis score from three caller-supplied boolean clinical flags: rebound tenderness/guarding, hematocrit, and serum creatinine.

How this service works
HAPS (Lankisch 2009). Harmless iff rebound tenderness and/or guarding is absent, hematocrit is normal, and serum creatinine is normal. The caller assigns each flag as already determined. magent does not examine the abdomen and does not measure hematocrit or creatinine. No millimetre or sex lab cutoffs. Not a medical device, not a diagnosis, and not a discharge order.
Output
Returns a structured HAPS result indicating whether the acute pancreatitis case is classified as 'harmless' per the Lankisch 2009 criteria — i.e., all three conditions met: rebound tenderness/guarding absent, hematocrit normal, and serum creatinine normal. Not a diagnosis or discharge order.
Example use cases
ED triage of mild pancreatitis
“I'm evaluating a patient in the ED with acute pancreatitis — no rebound tenderness or guarding, hematocrit is normal, and creatinine is normal. Can you calculate the HAPS score to see if this case qualifies as harmless?”
Clinical documentation workflow
“For my discharge note, I need the HAPS harmless pancreatitis score: the patient has rebound tenderness present, hematocrit is normal, but creatinine is not normal.”
Pancreatitis severity screening
“Run the Lankisch 2009 HAPS score for this pancreatitis patient — guarding is absent, hematocrit is normal, and serum creatinine is also normal. Is this a harmless case?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/hapsWhen to prefer
Use this endpoint when you need to programmatically apply the HAPS (Lankisch 2009) harmless acute pancreatitis score and already have clinical determinations for rebound/guarding, hematocrit, and creatinine as boolean flags. Prefer this over manual scoring when building clinical workflows, decision-support agents, or documentation pipelines that handle pancreatitis triage.
Side effects
- Missing required boolean flags (rebound_or_guarding, hematocrit_normal, creatinine_normal) returns a validation error
- Non-boolean values for flag parameters cause schema rejection
- Payment not provided returns 402 Payment Required
