# LongevityPulse Epigenetic Clock & Biological Age Intelligence

> LongevityPulse Epigenetic Clock & Biological Age Intelligence is a paid API for AI agents from longevitypulse.theaslangroupllc.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).

Returns intelligence on epigenetic clocks (GrimAge, DunedinPACE, Horvath, PhenoAge), explaining biological vs chronological age, how to test it, and evidence-based ways to slow or reverse aging.

## Facts

- Endpoint: GET https://longevitypulse.theaslangroupllc.com/api/longevity/epigenetic-clock
- Price: $0.2/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/longevitypulse-epigenetic-clock-biological-age-intelligence-a34790da
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vEq3RNpAKWT1hbbldC9zm

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-epigenetic-clock-biological-age-intelligence-a34790da
```

Example prompt: Can you explain how GrimAge and DunedinPACE epigenetic clocks differ, what my biological age result actually means if I'm 42 chronologically but scoring 38 biologically, and what are the top evidence-based steps I can take to keep slowing my biological aging rate?

## When to prefer this

Choose this endpoint when a user needs detailed, authoritative explanations of epigenetic clocks (GrimAge, DunedinPACE, Horvath, PhenoAge), wants to understand biological vs chronological age, or seeks evidence-based guidance on slowing biological aging. Prefer over general health endpoints when the query is specifically about epigenetic age measurement or aging rate science.

## Known failure modes

- Unsupported clock type or metric name returns no results
- Overly vague queries may return generic rather than targeted epigenetic clock information
- Network timeout if the upstream intelligence service is unavailable
- Payment failure (HTTP 402) if USDC balance is insufficient for the $0.20 per-call fee

## How this service works

Epigenetic clock / biological age intelligence (GrimAge, DunedinPACE, Horvath, PhenoAge) for longevity and health agents. Explains biological vs chronological age, how to test your biological age, and evidence-based ways to slow or reverse it. Health intelligence, not medical advice.

## Output

Returns structured health intelligence covering how epigenetic clocks (GrimAge, DunedinPACE, Horvath, PhenoAge) measure biological age, the distinction between biological and chronological age, guidance on how to test your biological age, and evidence-based interventions to slow or reverse aging — all framed as health intelligence, not medical advice.
