x402
Hestia Criteria Calculator for Outpatient PE Eligibility 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).
Evaluates the Hestia criteria (Zondag 2011) to determine whether a pulmonary embolism patient is eligible for outpatient/home treatment by checking 11 clinical exclusion criteria

How this service works
Hestia criteria (Zondag 2011). Outpatient PE is eligible only when none of 11 caller-assigned exclusions hold: hemodynamic instability, thrombolysis or embolectomy, high bleeding risk, oxygen >24 h, PE on anticoagulation, IV pain medication >24 h, medical or social admission, CrCl <30, severe liver impairment, pregnancy, or documented HIT. Any yes excludes home treatment. Not a diagnosis, not PESI, not sPESI.
Output
Returns whether the patient is eligible for outpatient (home) PE treatment based on the Hestia criteria, along with which of the 11 exclusion criteria were triggered. Any single 'true' exclusion disqualifies home treatment. The result is a binary eligibility decision with supporting criterion-level detail.
Example use cases
ED discharge decision for PE patient
“I have a PE patient in the ED — hemodynamically stable, doesn't need thrombolysis, no significant bleeding risk, oxygen requirement is fine, PE wasn't on anticoagulation, no IV pain meds needed beyond 24h, no social issues, creatinine clearance is normal, no liver problems, not pregnant, and no HIT history. Run the Hestia criteria and tell me if she can go home.”
Hospitalist admission avoidance screening
“Can you run the Hestia criteria on this new PE patient? He's stable, no embolectomy planned, some concern about bleeding risk so mark that true, no prolonged oxygen need, PE wasn't diagnosed while on anticoagulants, no IV pain meds, no social admission issue, creatinine clearance above 30, no liver impairment, not pregnant, no HIT — does he still qualify for outpatient treatment?”
Automated PE triage workflow integration
“For this PE patient, run the Hestia exclusion check with all 11 criteria: unstable=false, thrombolysis=false, high bleed risk=false, oxygen>24h=false, PE on anticoagulation=false, IV pain meds=false, medical or social admission=false, CrCl<30=false, liver impairment=false, pregnant=false, HIT=false — confirm whether outpatient management is appropriate.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/hestiaWhen to prefer
Use this endpoint when you need a fast, structured evaluation of the Hestia criteria specifically for PE outpatient eligibility decisions. Prefer this over manual checklist approaches or PESI/sPESI calculators when the clinical question is specifically about home treatment safety per the Zondag 2011 protocol. This is not a severity score — it is an eligibility gate for outpatient management.
Side effects
- Missing any of the 11 required boolean parameters returns a validation error
- Invalid parameter types (non-boolean values) cause a schema error
- Network timeout or API unavailability returns a 5xx error
- Payment failure via x402 protocol blocks the request
