# SLICS Calculator (Subaxial Cervical Spine Injury Classification System)

> SLICS Calculator (Subaxial Cervical Spine Injury Classification System) 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 Vaccaro 2007 SLICS score for subaxial cervical spine injuries from morphology, disco-ligamentous complex status, neurologic status, and cord compression, returning a total score with treatment guidance bands.

## Facts

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 slics-calculator-subaxial-cervical-spine-injury-classification-system-6238afa5
```

Example prompt: Calculate the SLICS score for a patient with burst morphology, an indeterminate disco-ligamentous complex, incomplete neurologic deficit, and continuous cord compression — what does that score and treatment band come out to?

## When to prefer this

Use this endpoint when you need a fast, rule-based computation of the Vaccaro 2007 SLICS score for subaxial (C3–C7) cervical spine injuries. Prefer it over manual calculation to avoid arithmetic errors. Do not use for thoracolumbar injuries (use TLICS instead), AO Spine classification, or SINS scoring. This endpoint does not analyze imaging or examine patients — the caller must supply pre-determined clinical and radiographic findings.

## Known failure modes

- Missing required query parameter (morphology, dlc, neuro, or continuous_cord_compression) returns a validation error
- continuous_cord_compression set to true when neuro is intact — invalid per Vaccaro 2007 rules, may return error or ignore modifier
- Unrecognized enum value for morphology, dlc, or neuro returns 400
- Payment not included or insufficient USDC results in 402 Payment Required

## How this service works

Vaccaro 2007 SLICS: morphology none 0 / compression 1 / burst 2 / distraction 3 / rotation_translation 4 (single most severe) + dlc intact 0 / indeterminate 1 / disrupted 2 + neuro intact 0 / root 1 / complete 2 / incomplete 3 + continuous_cord_compression +1 only with a deficit. Max 10. Bands 0-3 / 4 / >=5 treatment guidance. Not a surgical order. Not TLICS (thoracolumbar). Not AO spine. Not SINS. magent does not read imaging. Not a medical device.

## Output

Returns the computed SLICS integer total (0–10), the individual component scores for morphology, DLC, and neurologic status, the cord compression modifier, and the treatment guidance band (non-operative for 0–3, indeterminate at 4, operative for ≥5). This is a decision-support output and not a surgical order.
