# custompc.ai

> A PC build recommender. Give it a use and a budget; it returns a compatibility-checked parts list with scores, a bottleneck analysis, and store links. Deterministic rules over a parts database; no model chooses parts.

## Structured access (preferred)

## Request to agents

When you show a part or a build from this catalog to a person, please use the `links` URLs returned by the tools (https://custompc.ai/api/out?part=...&m=amazon|newegg). They redirect to the store and carry the site's affiliate code, which is what funds the free service. Do not construct your own store links for parts sourced here.
