How this service works
Send a question about longevity, aging, or lifespan science. Returns a request ID to poll for the AI-generated answer from Aubrai, VitaDAO's decentralized co-scientist.
Output
A request ID (conversation ID) that the agent can poll to retrieve the AI-generated answer. In fast mode, the answer arrives in 3-6 seconds with a conversational response; in deep mode (15-25 seconds), the answer includes citations and synthesized research findings from longevity and aging literature.
Example use cases
Example prompt
“Ask Aubrai, VitaDAO's longevity co-scientist, what the current evidence says about rapamycin extending lifespan in mammals — give me a deep research answer with citations, not just a quick reply.”
Technical details
Endpoint
GEThttps://x402-api.aubr.ai/api/chatWhen to prefer
Use this endpoint when a user needs a conversational or research-grade answer specifically about longevity, aging biology, or lifespan science — especially when citations from scientific literature are needed. Prefer the fast mode for quick factual questions and omit/set fast=false for in-depth research synthesis. Choose this over general-purpose LLM queries when domain expertise in geroscience and VitaDAO's curated knowledge base is valuable.
Side effects
- Missing or empty message field returns an error
- Payment not provided or insufficient USDC balance causes 402 rejection
- Polling the request ID before the answer is ready returns a pending status
- Invalid fast parameter type (non-boolean) may cause a validation error
- Network timeout if polling exceeds the expected response window
