# Facts

`list_asin_facts`

Lists the product **facts** Autopilot holds for an ASIN. A fact is a specific, verifiable product attribute — a material, a dimension, a certification, a capability — each with the evidence behind it and a confidence level. Facts are the factual foundation the USPs and optimized content are built on.

## When it's used

Use it to see what Autopilot knows to be true about a product and how strongly it's supported. Common questions: what are the verified facts, which are backed by reviews or spec sheets, and how confident is each. Facts are written in the listing's own locale.

## What you can ask

> *"What verified facts does Autopilot have for B07XYZ1234 in the US?"*

> *"Show the high-confidence facts for this ASIN and where each one comes from."*

> *"Which facts are backed by customer reviews?"*
