x402
2HELPS2B Score Calculator (Struck 2017) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).
Computes the 2HELPS2B score for estimating probable seizure risk from EEG pattern features pre-assigned by a clinician, returning a total score and associated seizure probability.

How this service works
Struck 2017 2HELPS2B: BIRDs 2 points; LPD or LRDA or BIPD, prior seizure, sporadic epileptiform discharges, frequency >2.0 Hz, and plus features 1 point each. Max 7. Published probable seizure risk: 0→5%, 1→12%, 2→27%, 3→50%, 4→73%, 5→88%, 6–7→>95%. Not a seizure diagnosis or monitoring-duration protocol. magent does not read EEG.
Output
Returns a numeric 2HELPS2B total score (0–7) derived from the submitted boolean flags, along with the published probable seizure risk percentage corresponding to that score (e.g., score 0→5%, 1→12%, 2→27%, 3→50%, 4→73%, 5→88%, 6–7→>95%). Does not include EEG waveform interpretation or a clinical diagnosis.
Example use cases
ICU seizure risk triage
“My ICU patient has LPD on EEG, a prior acute seizure, frequency over 2 Hz, and plus features but no BIRDs and no sporadic epileptiform discharges — calculate the 2HELPS2B score and tell me the seizure probability.”
Neurology consult risk stratification
“For a neurology consult note, I need the Struck 2017 2HELPS2B score for a patient with BIRDs and sporadic epileptiform discharges but no LPD/LRDA/BIPD, no prior seizure, frequency not exceeding 2 Hz, and no plus features.”
Clinical decision support documentation
“Can you compute the 2HELPS2B score for a patient with no BIRDs, BIPD present, prior remote seizure, sporadic epileptiform discharges, frequency above 2 Hz, and plus features? I need the score and the published seizure risk percentage for the chart.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/2helps2bWhen to prefer
Use this endpoint when a clinician or clinical decision support system has already interpreted the EEG and needs to arithmetically apply the Struck 2017 2HELPS2B scoring formula to pre-assigned binary features. Prefer this over manual calculation when building automated neurology workflows, ICU decision support agents, or documentation tools that must reliably produce the published seizure risk percentage without arithmetic error. Do not use this endpoint to interpret raw EEG signals — it accepts only pre-classified flags.
Side effects
- Missing required boolean parameter returns a 400 error
- Non-boolean value passed for a flag field causes schema validation failure
- Network timeout if the API is temporarily unavailable
- Score of 6 or 7 both map to >95% — no finer-grained probability is returned at the top range
