# Aubrai Biological & Scientific Data Analysis

> Aubrai Biological & Scientific Data Analysis is a paid API for AI agents from x402-api.aubr.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Runs an AI analysis task on biological or scientific data, returning structured findings, a direct answer, and a reasoning chain

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 x402-api-aubr-ai-1f2b925f
```

Example prompt: Analyze these uploaded files (IDs: file_abc123, file_def456) for signs of cellular aging and oxidative stress markers — I need structured findings, a direct answer, and the full reasoning chain behind your conclusions.

## When to prefer this

Use this endpoint when you need structured AI reasoning over biological or scientific datasets — especially when you want not just an answer but an explicit reasoning chain and organized findings. Prefer this over the literature search endpoints when you have actual data files to analyze rather than research questions alone.

## Known failure modes

- Missing or invalid taskDescription returns an error
- Unrecognized or expired fileIds may cause file-not-found errors
- Overly vague task descriptions may yield low-confidence or generic results
- Rate limiting or payment failure (x402) blocks access
- Very large files may cause timeouts or truncated analysis

## How this service works

Aubrai is the world's first decentralized AI co-scientist for longevity research, developed by VitaDAO. Orchestrates specialized sub-agents for literature synthesis, data analysis, and hypothesis generation to deliver comprehensive scientific reports on aging and lifespan extension.

All endpoints are gated by x402 micropayments using USDC on Base. Clients receive a `402 Payment Required` response with payment requirements, then retry with a signed `PAYMENT-SIGNATURE` header.

See [x402 docs](https://docs.cdp.coinbase.com/x402/core-concepts/how-it-works) for details.

## Output

Returns structured findings summarizing key observations, a direct answer to the analysis task, and a step-by-step reasoning chain explaining how the conclusions were reached
