analyze_listing

Start a BuyerAware pre-purchase verdict on ONE used vehicle. Runs a mechanic-grade read: ranked failure points with $ exposure, recalls, seller-claim fact-check, fair price range, adjusted true cost, risk score 1-10, BUY / BUY_WITH_CONDITIONS / WALK_AWAY, a word-for-word negotiation script, and lower-risk 'Tank' alternatives. Supply whichever of listing_url, listing_text or vin you have — at least one is required, and more context sharpens the verdict. Takes ~1-2 minutes: returns a job_id, then poll get_verdict. Costs 1 credit. For 'what should I buy instead' use tank_alternatives, which is free.

vinstring

17-character VIN, if the listing shows one

locationstring

buyer city/state, for pricing and inspection context

listing_urlstring

link to the listing — Marketplace, Craigslist, AutoTrader, a dealer page

listing_textstring

the listing copy pasted as-is, when there is no shareable URL

buyer_contextstring

what the buyer needs it for, budget, and any specific concerns

create_trial_key

Create a BuyerAware API key so this user can run verdicts (3 free). Call this once when no key is configured, then show the user the key and tell them to save it. Do not call it again for someone who already has a key — one trial per email address.

Argument	Type	Description
name	string	optional display name for the key record
email*	string	the user's email address; the key is issued against it, one trial key per address

tank_alternatives

FREE, no API key needed, answers instantly. Recommend 2-3 lower-risk used vehicles ('Tanks') from BuyerAware's curated 47-platform database that land near a budget. Use when a buyer asks what to buy instead, or what is reliable for $X. Use analyze_listing instead when they have a specific car in mind.
