# SINS Score Calculator (Fisher 2010)

> SINS Score Calculator (Fisher 2010) 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).

Computes the Spinal Instability Neoplastic Score (SINS) integer total from six caller-assigned clinical and radiographic parameters per Fisher 2010.

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 sins-score-calculator-fisher-2010-5b74bf53
```

Example prompt: Calculate the SINS score for a patient with a junctional spinal metastasis, mechanical pain, a lytic lesion, subluxation on imaging, greater than 50% vertebral collapse, and bilateral posterolateral involvement.

## When to prefer this

Use this endpoint when you need a programmatic, deterministic computation of the Fisher 2010 SINS integer total from already-adjudicated clinical and radiographic parameters. It is purpose-built for SINS only — not TLICS, not later SOSG stratification tables, and not any other spinal scoring system. Prefer it over general-purpose LLM arithmetic when you need a reliable, auditable numeric output with defined subscores.

## Known failure modes

- Missing required query parameter returns validation error
- Invalid enum value for any parameter returns 400-level error
- Score is only as accurate as caller-assigned inputs — magent does not read imaging or interview the patient
- Does not implement SOSG strata, TLICS, or operative indications — only the raw integer sum

## How this service works

Fisher 2010 SINS. Location junctional 3 / mobile 2 / semirigid 1 / rigid 0. Pain mechanical 3 / occasional_not_mechanical 1 / pain_free 0. Bone lytic 2 / mixed 1 / blastic 0. Alignment subluxation_translation 4 / de_novo_deformity 2 / normal 0. Collapse gt_50 3 / le_50 2 / no_collapse_gt_50pct_body 1 / none 0. Posterolateral bilateral 3 / unilateral 1 / none 0. Max 18. Integer sum only; not later SOSG strata, not TLICS, not an operative order. magent does not read imaging. Not a medical device.

## Output

Returns an integer SINS total (0–18) computed by summing the six subscores: location (0–3), pain (0 or 1 or 3), bone quality (0–2), alignment (0, 2, or 4), collapse (0–3), and posterolateral involvement (0, 1, or 3). Higher scores indicate greater neoplastic spinal instability.
