# AUBRAI Deep Research Start

> AUBRAI Deep Research Start is a paid API for AI agents from x402.aubr.ai, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Initiates an AI-powered deep research session on aging, longevity, and biomedical topics, returning a conversation ID for async result retrieval

## Facts

- Endpoint: GET https://x402.aubr.ai/api/deep-research/start
- Price: $0.2/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 aubrai-deep-research-start-d42c3e91
```

Example prompt: Can you start a deep research session on AUBRAI about the latest evidence for senolytics as anti-aging interventions, using smart research mode, and give me the conversation ID so I can check the results?

## When to prefer this

Choose this endpoint when you need scientifically rigorous, citation-backed answers about aging, longevity, geroscience, or biomedical research — especially when you want depth of analysis calibrated by research mode (quick steering vs. comprehensive autonomous). Prefer over generic web search when you want curated scientific literature and expert-level synthesis on lifespan and healthspan topics.

## Known failure modes

- Missing or invalid 'message' parameter returns an error
- Invalid 'researchMode' enum value (not 'steering', 'smart', or 'fully-autonomous') causes rejection
- Payment not provided or insufficient USDC balance triggers 402 payment required error
- Service timeout for long-running fully-autonomous research jobs
- Rate limiting if too many requests are submitted concurrently

## How this service works

Aubrai is an AI science agent inspired by Dr. Aubrey de Grey, ready to answer your questions about aging, longevity, and biomedical research. Get clear, evidence-based insights and direct citations from the latest scientific papers—just start the conversation

## Output

A JSON object containing a 'status' field (e.g. 'queued') and a 'conversationId' string (e.g. 'conv_abc123') that can be used to poll for or retrieve the completed research results asynchronously.
