  • 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.

Capabilities

Tools 9

api_account

For a developer using the GolfCore Course Data API: list the API accounts the signed-in person can see, or read one with its plan, this month's usage, monthly cap if one is set, and keys (prefixes only, never secrets). Use it before the other api_ tools to get account_id and key_id. Plans: free, 500 requests a month at 10 a minute; basic, $10 a month for 10,000 at 60 a minute, then $2.00 per 1,000; business, $50 a month for 100,000 at 300 a minute, then $1.00 per 1,000. Paid plans have no monthly cap unless the person sets one. If the person has no account, they create one at https://platform.golfcore.app.

Discovered
api_budget

Starter and Pro have no monthly cap by default: requests past the included amount are billed at the plan's overage rate without limit. This tool sets an optional cap, after which requests are refused until the month resets, or removes it when units is null. A cap starts at the plan's included requests (read them from api_account). Confirm the number and what it could cost with the person first.

Discovered
api_create_key

Create a GolfCore Course Data API key for the signed-in person's account. Returns the secret once; hand it to the person to store in their server's configuration, and never put it in chat logs, code, a mobile app or browser code. Confirm the name with the person first.

Discovered
api_revoke_key

Revoke one of the signed-in person's GolfCore API keys. Requests with it are refused within about a minute, and it cannot be restored. Confirm the key's name and prefix with the person before calling.

Discovered
api_upgrade

Start an upgrade of the signed-in person's GolfCore API account to basic ($10 a month for 10,000 requests, then $2.00 per 1,000) or business ($50 a month for 100,000, then $1.00 per 1,000). Returns a Stripe checkout URL for the person to review and pay; this tool does not charge them. If the account already has a paid plan it returns the billing page, where the person switches plans themselves. Ask which plan they want first.

Discovered
ask_caddie

Ask GolfCore's caddie a question about the shot the golfer is standing over, such as which club to hit or where to aim. Pass the question in their words, and lat and lng only if your device gives you their GPS position; otherwise GolfCore uses the position from the GolfCore app on their phone. The caddie reads the distance to the flag, the hazards and trees on the line, wind modeled for the terrain, the elevation change, and the golfer's own handicap and club distances from their GolfCore account, and answers with a club and a line; the golfer signs in to GolfCore the first time. It needs GolfCore Premium; without it the result lists the plans, and subscribe_premium starts one.

Discovered
distance_to_flag

How far the golfer is from the flag, from where they are standing: 'how far is that flag', 'what's the yardage'. Returns the course, the hole, its par and stroke index, and yards to the flag (today's pin as the club set it) and to the middle of the green. Pass lat and lng only if your device gives you the golfer's GPS position; otherwise call it with no arguments, and GolfCore reads the golfer's position from the GolfCore app on their phone. It is part of GolfCore Premium: the golfer signs in to GolfCore the first time, and without Premium the result lists the plans for subscribe_premium. position_age_s says how old that position is. When hole_inferred is true the hole was chosen from the position, so say which hole you assumed.

Discovered
search

Search everything GolfCore holds for more than 30,000 golf courses in more than 180 countries and territories. Ask by course name ('Pebble Beach'), by its name in local script ('宮崎カントリークラブ'), by architect ('Donald Ross'), by slug ('pebble-beach'), by place, passing just the place name ('St Andrews', 'Monterey'), or about GolfCore itself ('what does a caddie master use GolfCore for'). A course comes back with its address, town, region, country, coordinates, timezone, phone and website, its architect and the year it opened where known, and its name in Japanese or Korean script where that differs; flags for what GolfCore has mapped -- lidar green contours, a traced map of fairways, tees, greens, bunkers and water, a live wind grid, a scorecard, USGA ratings; and, when scope includes scorecards, its full card: par, yardage and stroke index for every hole, and yardage, par, course rating and slope rating for every tee, separately for men and women. Places come back as the town, region or country page that counts and lists every course there. Pages come from GolfCore's own site. Every result carries the url to cite, and a course's page carries the green figures this tool does not: greens mapped, contour count and interval, largest green elevation span, steepest measured slope, and tree canopy. For 'courses near me' or 'near this hotel', pass near with the person's coordinates: courses come back nearest first with their distance in miles, and query may be left empty. Each course also carries app_url, the link that opens that course's map in the GolfCore app, in a browser or on a phone, with no account needed to start; append &hole=N to open on a given hole.

Discovered
subscribe_premium

Create a GolfCore Premium checkout link for the signed-in golfer. Premium adds the caddie in this connector and the GolfCore app, plus green contour maps, live wind and offline course packs. Plans: day_pass, $3 for 24 hours of Premium, one charge and no subscription, the popular choice for a golfer on the course today; plus_monthly, $10 a month; and plus_yearly, $100 a year. A first-time subscriber pays half for the first month or first year. Ask the golfer which plan they want before calling. Returns a secure Stripe checkout URL and the current plan terms. Give the link to the golfer to review and pay; this tool does not charge them or activate Premium.
