# Macfax

> Macfax is the trust layer for the used-Mac market: verified condition reports for individual Macs, a quality-gated marketplace of live used-Mac listings aggregated across eBay, Craigslist, OfferUp, Swappa, Facebook and Reddit, and asking-price statistics per exact configuration. All prices Macfax publishes are asking prices, not sold prices, and every listing links out to the original source. Macfax is not affiliated with Apple Inc.

Machine access in one line: the free JSON API at https://macfax.com/api/v1 answers lookups, price stats, listing search, listing checks, report fetches and alert creation without an account. Docs: https://macfax.com/developers · OpenAPI: https://macfax.com/api/v1/openapi.json

## API for agents

- [Developer docs](https://macfax.com/developers): every endpoint, rate limits, key minting (`POST /api/v1/keys`, no email required), attribution rules.
- [OpenAPI spec](https://macfax.com/api/v1/openapi.json): machine-readable contract for all /api/v1 endpoints.
- [Price stats](https://macfax.com/api/v1/price-stats?config=macbook-pro-14-m3pro-2023): median/p25/p75 asking price, sample size, per-channel split for a configuration key.
- [Listing search](https://macfax.com/api/v1/listings?config=macbook-pro-14-m3pro-2023): live, scam/junk/stale-filtered listings with deep links to the source marketplace.
- [Listing check](https://macfax.com/api/v1/check-listing?url=...): is this specific listing known, still live, fairly priced, flagged, or verified?
