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 magent-resect-90-lung-resection-90-day-mortality-calculator-88800aab
```

Example prompt: Using the RESECT-90 model, estimate 90-day mortality risk for a 68-year-old male with ECOG 1, DLCO 72% predicted, BMI 26.4, creatinine 95 umol/L, no anaemia, no arrhythmia, right-sided malignant resection via VATS involving 3 segments.

## When to prefer this

Choose this endpoint when you need a validated, published logistic model (Taylor 2021) for 90-day mortality after lung resection and all 12 clinical variables have already been assigned by a clinician. Prefer this over generic LLM-based risk estimates when you need a reproducible, coefficient-based numeric probability. Not appropriate as a sole operative go/no-go decision tool or as a substitute for clinical judgment.

## Known failure modes

- Missing any of the 12 required query parameters returns a validation error
- Age outside 18-120 range rejected
- BMI outside 10-80 range rejected
- Invalid enum values for sex, laterality, surgical_approach, or diagnosis return error
- Non-boolean values for anemia or arrhythmia fields cause schema validation failure
- ECOG value outside 0-4 range rejected
- Creatinine value out of plausible range may be rejected
- Payment not included or insufficient USDC balance causes x402 payment-required error

## How this service works

Taylor 2021 RESECT-90 logistic 90-day mortality after lung resection from age, sex, ECOG, percent predicted DLCO, BMI, creatinine (umol/L), anaemia, arrhythmia, laterality, thoracotomy vs VATS, diagnosis, and resected segments. Returns logit and estimated_mortality_percent. Not a medical device, not an operative go/no-go, and not a published cutoff. magent does not assign ECOG or read spirometry.

## Output

Returns a JSON object with two fields: 'logit' (the raw linear predictor from the Taylor 2021 Table 3 coefficients) and 'estimated_mortality_percent' (the back-transformed probability of 90-day mortality expressed as a percentage). Does not return a go/no-go recommendation or a published decision cutoff.
