# ForeverBetter Longevity API – Read Normalized Source

> ForeverBetter Longevity API – Read Normalized Source is a paid API for AI agents from api.foreverbetter.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Retrieve a normalized health data source (genetic, biomarker, or wearable) by its source ID for the authenticated wallet owner.

## Facts

- Endpoint: GET https://api.foreverbetter.xyz/sources/%7Bid%7D
- Price: $0.005/call
- Payment: x402
- Status: unknown

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 foreverbetter-longevity-api-read-normalized-source-2db81ecb
```

Example prompt: Pull my normalized health source with ID src_abc123 from ForeverBetter — I want to see all the observations that came back from my last lab panel upload.

## When to prefer this

Use this endpoint when you have already submitted a health data source (lab panel, genetic file, or wearable sync) and need to retrieve the resulting normalized observations by source ID. Prefer this over re-submitting data when the source already exists. This is the read step in a submit → read → analyze → action-plan workflow.

## Known failure modes

- Source ID not found or does not belong to the paying wallet — returns empty or 404-equivalent
- Invalid or missing source ID format — returns schema validation error
- Payment not received or insufficient USDC — x402 payment required error
- Source still processing — observations array may be empty or incomplete
- Wallet mismatch — source owned by a different wallet returns unauthorized

## How this service works

Send raw genetic data, a lab panel, or sync wearables. Get back normalized observations, in-depth analysis, and customized action plans over REST and MCP. Built for agents and platforms.

## Output

A JSON object containing the source record (with its ID and metadata) and an array of normalized_observations derived from the original genetic, lab, or wearable data submitted. Each observation is standardized into a common schema for downstream analysis or action-plan generation.
