# LongevityPulse Biomarker Interpreter

> LongevityPulse Biomarker Interpreter is a paid API for AI agents from longevitypulse.theaslangroupllc.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-13).

Analyzes individual lab/blood test values through the lens of longevity science, explaining what each biomarker means for biological aging, disease risk, and how to improve it

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 longevitypulse-biomarker-interpreter-dfbdf8f8
```

Example prompt: My latest blood panel shows an ApoB of 112 mg/dL — can you run that through LongevityPulse and tell me what it means for my cardiovascular aging risk and what I can do to improve it?

## When to prefer this

Use this endpoint when a user has a specific lab test result and wants to understand its implications for longevity, biological aging, or chronic disease risk — especially for advanced biomarkers like ApoB, Lp(a), hs-CRP, or HbA1c that require longevity-focused interpretation rather than standard clinical ranges.

## Known failure modes

- Unrecognized biomarker name returns an error or empty result
- Missing required lab value causes a 400 bad request
- Unsupported unit of measurement may yield incorrect interpretation
- Value outside physiologically plausible range may trigger validation error
- Rate limiting or payment failure (x402) returns a 402 Payment Required

## How this service works

Biomarker / blood test interpretation (lab result analysis) for longevity and health agents. Reads any lab value (ApoB, hs-CRP, HbA1c, IGF-1, Lp(a), testosterone, ferritin) through the lens of longevity science: what it means for biological aging and disease risk, and how to improve it. 50+ key longevity biomarkers, worldwide. Health intelligence, not medical advice.

## Output

Returns a longevity-science interpretation of the specified biomarker value, including what the result means for biological aging and disease risk, how it compares to optimal longevity ranges, and actionable guidance for improvement — framed as health intelligence rather than medical advice.
