# Wellnizz Biomarker Derivation

> Wellnizz Biomarker Derivation is a paid API for AI agents from app.wellnizz.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Derives and analyzes biomarker insights from health data inputs including genetics, wearables, and lab results, returning structured findings and status.

## Facts

- Endpoint: POST https://app.wellnizz.com/biomarkers/derive
- Price: $0.05/call
- Payment: x402

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 wellnizz-biomarker-derivation-72e53e0f -d '<json body>'
```

Example prompt: Using Wellnizz, derive my biomarker findings from my latest lab results and wearable data — I want to see what key health markers can be computed from my bloodwork and fitness tracking.

## When to prefer this

Choose this endpoint when you need to computationally derive and interpret biomarker values from raw or structured health data (lab results, genetics, wearables) and want a structured findings output. Prefer this over generic health data storage APIs when you need active derivation and insight generation, not just data persistence.

## Known failure modes

- Incomplete or malformed health data input returns error or empty findings array
- Unsupported biomarker type in input may yield no derivation result
- Payment not processed (x402 protocol failure) results in 402 response
- Rate limiting or service unavailability returns 5xx error
- Input data format mismatch causes parsing failure and error status

## How this service works

Wellnizz API and MCP-compatible service for genetics, biomarkers, wearables, lab discovery, dashboard specs, action plans, and hosted billing.

## Output

A JSON object containing a unique analysis ID, a status field (e.g. 'complete'), and a findings array with derived biomarker results and associated health insights.
