search_bikes — Search bikes for sale
Search live UK used-bike listings on Cyclesite (the UK's used bicycle marketplace). Filter by brand, category, city, price range, and condition. Returns up to 5 active listings with specs and listing URLs. Live data — refreshed continuously as new bikes are listed. Example queries: 'a Trek Domane in Manchester under £2,000', 'gravel bike, very good condition, near Bristol'.

}get_listing_detail — Get listing detail
Full details for a specific bike listing on Cyclesite: specs, condition, frame number presence, photos, delivery, seller's city. Takes the URL slug from a listing result. Example: 'tell me more about that 2022 Trek Domane'. The marketplace is not the seller: contact goes through the route in `howToContactSeller`, delivery terms are only what `delivery.summary` states, and no seller has agreed a price or delivery through this tool.

}search_by_location — Search by location
Find Cyclesite listings within a radius of a UK town, city or postcode district (the first half of a postcode, e.g. 'BS1', 'M20'). A full postcode is cut to its district; coordinates are not accepted. Radius capped at 50 miles. Returns up to 10 listings ordered by distance, rounded to the mile, and `searchedFrom` naming the place measured from. Live UK marketplace data. Example: 'used bikes within 25 miles of Leicester' or 'road bikes near LE10'.

}get_valuation — Get valuation
What a used UK bike is worth right now, Cyclesite's flagship tool. Returns median, range, a measured price-by-model-year curve, confidence level, and comparable active listings. When `year` is given, the answer is resolved against that model year's own measured median and confidence interval, instead of the all-years median. Sourced from real UK sold prices, refreshed nightly. Example: 'what's a 2022 Trek Domane SL 6 worth?'.

}suggest_listing_price — Suggest listing price
For a seller about to list: suggested ask, floor, and ceiling for their bike's brand+model[+year][+condition] on the UK market. Same measured UK used-price data as the valuations, framed as seller guidance. When `year` is given, the ask is anchored on that model year's own median rather than the all-years median. Example: 'I'm selling a 2021 Specialized Allez in good condition, what should I ask?'.

}grade_listing_quality — Grade listing quality
Categorical quality grade for a Cyclesite listing (excellent / good / fair / weak) plus up to 2 wins and 2 flags. Helps a buyer assess trustworthiness; helps a seller self-audit. Example: 'is this listing trustworthy?' (provide the slug). Note: returns the *categorical* judgement only, not the underlying score (intentional to avoid gaming).

Sell-side helper: turn a seller's raw facts into a polished Cyclesite listing draft (title, description, suggested price, photo plan). Does not publish anything: publishing needs a signed-in account (OAuth). Useful for previewing what a listing would look like. Example: 'help me draft a listing for my 2021 Specialized Allez, very good condition, in Bristol'.

}check_stolen — Check a frame number
Check whether a UK bike's frame (serial) number matches a theft report held by Cyclesite. Live data, checked on every call. Rate-limited per serial number (3 an hour) to prevent enumeration. Example: 'does frame number WTU123456 match a theft report?'. Someone who has found a bike, rather than bought one, can check the frame number and leave the owner a message at https://www.cyclesite.co.uk/stolen-bikes/found.

}publish_listing — Publish a listing
Publish a Cyclesite listing on the user's behalf. Multi-step: the first call (no draftId) returns step:'photos_required' with a phone-friendly photo upload URL for the seller. Once 3+ photos are uploaded, a call with the same draftId returns either step:'live' (listing is free, no payment needed) or step:'payment_required' with a checkout URL. Idempotent: each call with the same draftId returns the current step. Requires OAuth scope `listings:publish`. When the listing goes live the seller receives a confirmation email with a 24h undo link. Example: 'sell my Trek Domane'.

}save_search — Save a search alert
Subscribe the user to email alerts for Cyclesite listings matching a filter. We email them when a matching bike is listed or drops in price, instantly or in a daily digest, depending on their email preferences. Requires OAuth scope `listings:read` (read-only on data, but this is technically a write: it creates a SavedSearch row on the user's account). Examples: 'let me know when a Trek Domane SL 6 in Manchester under £2,000 appears', 'alert me to any e-MTB drops below £2,500 in Yorkshire'. Each user is capped at 50 active alerts.

Per-buyer-per-listing daily cap (2/day) prevents spam. Requires OAuth scope `enquiries:respond` (the scope name is shared with seller-side replies).

}reserve_listing — Reserve listing (24h hold)
Hold a Cyclesite listing for 24 hours so other buyers can't claim it while the user decides. The hold is free and advisory: the seller isn't obligated to honour it. We never take a deposit or any payment for a bike; the buyer and seller arrange payment between them. Requires OAuth scope `listings:manage`.
