## What it does

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.

Audience: ai-agents, developers. Tags: data, aubrai, world, first.

## How agents pay

1. The agent sends a plain request and receives an HTTP 402 response describing the price and payment requirements.
2. The agent signs a payment payload for the exact amount on base and attaches it to a retried request.
3. The facilitator verifies and settles the payment, then the service returns the paid response.
