    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 713 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 713 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Every tool description is at least 20 characters.

  • Pass

    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 6

find_similar_cars

Given one listing, find comparable ones: same make, similar year, mileage and price band. Use this when the user likes a car but wants alternatives — 'find me something similar', 'the same but cheaper', 'what else is around this price'. Pass `maxPrice` for the cheaper case; without it, comparables are drawn from a band around the reference price. Comparability is by structure (make/model/year/km/price), not by text similarity: it answers 'is this well priced for what it is', which a keyword search cannot.

Discovered
get_car_detail

Get the complete record of one used-car listing in Portugal by its slug. Use this after search_cars when the user asks about a specific car: full description, features, photos, seller, and the original source URL to cite.

Discovered
get_price_stats

Get price statistics for a slice of the Portugal used-car market: how many listings match, the median price, the p25–p75 range, the median price per kilometre and a breakdown by body type. Use this when the user asks what something costs, whether an asking price is fair, or how two makes compare — instead of listing individual cars. Takes the same filters as search_cars and describes exactly the set that tool would return, so the two never disagree. Reports medians and quartiles rather than averages, because car prices have a long right tail and a single luxury listing moves an average.

Discovered
search_articles

Search editorial articles about the used-car market in Portugal: buying guides, reviews, comparisons and market analysis. Use this when the user asks how something works — financing, warranty, IUC, IPO/ITV, the buying process — rather than asking for listings.

Discovered
search_cars

Search current used-car listings for sale in Portugal. Use this whenever the user wants to find, compare or explore cars — by make, model, budget, mileage, fuel or district. Returns price, mileage, fuel, body and a citable listing URL, plus `total`: the exact number of listings matching the filters, which makes this tool usable to answer 'how many' questions. Listings are aggregated from stands and portals and refreshed daily; each result carries `publishedAt`. Prefer the broadest filters that answer the question and report `total` as a floor, not a census.

Discovered
search_cars_by_description

Search Portugal listings by describing the car in plain language, matched against listing text by meaning rather than keywords. Use this for wants that are not filter fields — 'a family SUV good in the snow', 'a low-mileage hybrid for the city', 'a used 4x4 to restore'. Prefer search_cars for entirely structural queries (make/model/budget); use this when the request is descriptive. Combine both by passing structural filters here too — they act as hard constraints while the description only ranks. Results are ordered by relevance, so `total` is the number matching the structural filters, not the number that fit the description.
