magent ECOG Performance Status Calculator
x402
magent ECOG Performance Status Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Validates and returns a structured ECOG performance status score (0–4) with label and citation, given a caller-assigned integer per the Oken 1982 scale

How this service works
Oken 1982 ECOG performance status: caller-assigned integer 0-4 (fully active; restricted strenuous activity, ambulatory, light work; ambulatory, all self-care, unable to work, up >50% waking hours; limited self-care, bed/chair >50% waking hours; completely disabled, no self-care, totally bed/chair). Grade 5 (dead) is not scored. Returns score, max 4, and a stable label. Not a performance-status assignment and not Karnofsky; magent does not observe the patient.
Output
Returns a JSON object containing the ECOG score (integer 0–4), the ecog_grade, the ecog_label (e.g. 'fully_active'), max_score (4), a components breakdown, the formula expression, a full Oken 1982 citation (DOI, PMID, title, authors, source), and a disclaimer that this is not a medical device and a licensed clinician is responsible for patient care.
Example use cases
Oncology trial eligibility check
“My trial protocol requires ECOG ≤ 2. The patient has been assigned ECOG grade 2 — can you return the structured score, label, and citation so I can document it in the workflow?”
Structured data entry for clinical pipeline
“I need to encode an ECOG performance status of 1 for a patient record — give me the full structured result with the Oken 1982 citation and the official label.”
Verify ECOG grade label for reporting
“What is the official Oken 1982 label for ECOG grade 3, and what does it mean? Return it in a structured format I can log.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ecogWhen to prefer
Use this endpoint when an AI agent needs a deterministic, citable, structured encoding of a caller-assigned ECOG performance status integer — especially in autonomous clinical, trial eligibility, or documentation workflows where a published reference (Oken 1982) and a stable label are required. Do not use if you need to assess or observe a patient's functional status, or if you need Karnofsky rather than ECOG scoring.
Side effects
- Missing or invalid 'ecog' query parameter — returns error if not provided
- Integer out of range (e.g. 5 or negative) — grade 5 (dead) is explicitly not scored
- Non-integer value for ecog parameter — type mismatch error
- Payment not processed — x402 payment required error before response is returned
