Tools
| Tool | Description | Behaviour |
|---|---|---|
| check_mac_listing | The trust picture for one specific listing, by URL (eBay/Craigslist/OfferUp/Swappa/Facebook/Reddit) or Macfax listing id: whether Macfax knows it, whether it still passes every quality gate, scam/junk/classified/auction flags, when a scan last verified it live, its ask against the configuration's typical asking band, the platform's own seller-reputation figures where the marketplace has them (seller_signals: eBay feedback, Swappa rating; null elsewhere), and whether a verified Macfax report is attached. Facts, not verdicts. | Read-only |
| create_mac_alert | Watch the market for a configuration: Macfax emails the given address when new matching listings appear. CONSENT CONTRACT: create an alert only for a user who explicitly asked for this alert on this email address. The first alert for a new email stays inactive until the email's owner clicks the confirmation link Macfax sends; nothing is emailed before that, and every alert email carries manage and unsubscribe links. | Changes data |
| get_mac_market_value | What a used Mac is worth, from the name Apple gives the model, e.g. "MacBook Pro (14-inch, 2021)" or "MacBook Air (13-inch, M4, 2025)". Returns every Apple Silicon configuration the name can mean, each with its sale estimate (verified sales, or the asking band scaled by a measured clearance ratio; basis labeled) and its live asking band, plus an estimate across them: a single mid when the name pins one configuration, a low-to-high range when Apple's name leaves the chip open. Apple Silicon Macs only. Use the sale estimate as the price of the Mac; asking is seller guidance. | Read-only |
| get_mac_price_stats | What a used Mac configuration actually sells for AND what sellers are asking right now. The sold slice is the headline: verified-sale percentiles when the config has enough recent sales (sold.basis 'direct'; n and window ride along), else the asking band scaled by a measured clearance ratio (sold.basis 'calibrated', ratio disclosed). The asking band (median/p25/p75 with sample size), per-channel medians with net-to-seller after fees, launch MSRP retention and Apple trade-in floor ride along as seller guidance. Use the sold estimate as the price of the Mac; use asking to set a list price. The slices are separate and never blended — preserve the basis label when quoting. | Read-only |
| get_mac_report | A verified Macfax condition report as structured data: hardware-verified identity, Activation Lock / MDM / serial-match checks, coverage status, and the signing chain. Use when a listing or seller shares a macfax.com/r/ link and the buyer wants the facts behind it. status "superseded" means the same Mac was re-verified more recently under a newer report; treat the payload as historical state, not current. | Read-only |
| get_macfax_credit_balance | How many serial resolutions this API key has left, and what actually costs a credit. Only a brand new resolution is billed: a 2021+ (10 character) serial Macfax has never resolved and that this key has not looked up in the last 24 hours. Cached serials, pre-2021 serials, repeats within 24 hours and every other tool are free at every tier. Call this before a large batch of serials to find out whether it can be finished. Without a key it reports the anonymous allowance instead. | Read-only |
| lookup_mac_serial | Resolve a Mac serial number to its exact model, including 2021+ randomized serials whose characters encode nothing (so no character-decoder can read them). Also returns what that model is worth (the market block: sale estimate and asking band per configuration) and whether a verified Macfax report exists for the serial. Lookup is advisory and cannot verify condition, Activation Lock, or possession; a Macfax report can. | Read-only |
| search_mac_listings | Live used-Mac listings aggregated across eBay, Craigslist, OfferUp, Swappa, Facebook and Reddit, with scam clusters, junk titles, classified-ad bait, auctions and stale/sold rows already filtered out. Every result deep-links to the source listing where the purchase happens. Filter by configuration, family, chip, RAM, storage, price ceiling, and verified-report tier. | Read-only |
