ELDRICK

Analyzes a golfer's current set from each club's type or number, loft and carry (total optional) plus an optional driver or 7-iron speed. Returns the carry and loft gap between consecutive clubs; flags for gaps that are too big or too small, duplicate lofts and overlapping distances; ELDRICK's recommended wedge set from the pitching wedge loft (master-fitter loft and bounce rules); and suggested changes (add, drop or replace a club, or change a loft), each with the analyze_fitting club type for that club (fitWith). Missing carries are estimated from loft and speed with ELDRICK's speed conversions, missing lofts use stock lofts, and both are marked as such. Free and deterministic; does not use a fitting.

analyze_bag_gapping

Runs a new ELDRICK club fitting for a driver, fairway wood, hybrid, irons or wedges (not putters) from the golfer's handedness and club speed (or ball speed), plus any optional details given: usual miss, ball flight, handicap, distances, height, wrist-to-floor and launch-monitor numbers. Cost: each new fitting uses one of the account's included monthly fittings or a purchased credit. A repeated call with the same idempotencyKey and input returns the same fitting and is not charged again. A fitting takes about 20-50 seconds and sends progress notifications. It returns as soon as the specs and matched clubs are final, with status "specs_ready": show them; the written analysis follows (get_fitting with the fittingId returns the full result). If the specs are not ready within waitSeconds (default 25), or async is true, the result has status "running" and a fittingId usable with get_fitting. A completed result contains the recommended specs (loft, flex, shaft weight, launch profile, length, lie, swing weight, head profile; wood gapping; wedge bounce and set), a written analysis consistent with those specs, topPicks (the top 3 heads, each with the reasons it suits this golfer, its fitted build and a store link), and the attribution line "Fit by ELDRICK". Developer API keys also get every matched head, shaft and grip (clubRecommendations). The fittingId also works with score_clubs and build_store_link.

analyze_fitting

Creates a one-tap checkout link for a club with the fitted build: store.eldrick.com/checkout?build=<signed token>. It opens ELDRICK's checkout page with the build already in the golfer's bag, ready to pay by card, Apple Pay, Google Pay or Link. Nothing is charged, reserved or ordered until the golfer pays on that page; the price, shipping and sales tax are confirmed there, and a fitter checks every spec before the club is built. Same fields as build_store_link (a headId and a fittingId fill every fitted spec; explicit option ids from get_club override it), plus qty. The link expires after 72 hours. Use build_store_link instead when the golfer wants to look, not buy. Free; does not use a fitting.

build_checkout_link

Creates a link to a club's page on store.eldrick.com with a fitted build listed and an estimated price. With a headId and a fittingId, every fitted spec the store uses goes into the link (hand, loft, shaft, flex, shaft weight, length, lie, swing weight; wedge bounce and set). Explicit fields (option ids from get_club) override the fitting. The result lists the URL parameters it set (urlParams). Links open the product page, never a checkout; nothing is bought or reserved. Free; does not use a fitting.

build_store_link

Compares 2 to 4 club heads (ids from search_clubs) side by side: price, category, bias, lofts, adjustability, hands, stock shafts and ELDRICK's recent recommendation counts, and lists which attributes differ. It does not judge which club suits a golfer (score_clubs does, for the same headIds). Free; does not use a fitting.

compare_clubs

Lists golf club fitters near a US ZIP code, a city and state, or a latitude and longitude, within a radius (default 50 miles), optionally only those that fit given clubs (driver, fairway_hybrid, irons, wedges, putter, full_bag) or a brand. Each result has the fitter's name, address, phone, website, booking link, distance in miles, recognition, rating with its source (only when one is published), services, brands and a partner flag. ELDRICK partners within the radius come first, labelled "ELDRICK partner", then the others by distance. Public business information from ELDRICK's fitter directory. Free; does not use a fitting.

find_fitter

Returns one club head from the ELDRICK catalog with its build options: lofts, hands, stock shafts (weight band, launch, flexes, upcharge), aftermarket shaft upgrades (drivers, woods, irons and wedges; each upgrade price is per club with the new head, and iron and wedge upgrades also list reshaftPrice, the per-club price to reshaft the golfer's own irons), grips, grip sizes, lengths, and for irons lie and set options. Its option ids are accepted by build_store_link. Free; does not use a fitting.

get_club

Returns the recommended golf grip size (junior, undersize, standard, midsize or jumbo) and extra wraps (none, +1 or +2) from the golfer's hand length and, optionally, longest-finger length in inches, with the reasoning from ELDRICK's master-fitter hand chart and catalog grips offered in that size (their gripIds and storeGripSize are accepted by build_store_link). Glove size and handedness are recorded but do not change the size. Without a hand length the result has status "needs_hand_length" and how to measure it. Applies to every club. Free and deterministic; does not use a fitting.

get_grip_size

Returns a fitting from this account by fittingId: the result of a finished fitting (the same shape as analyze_fitting, plus the saved input), or the status of one still running. For a running fitting it waits up to waitSeconds (default 20) and sends progress notifications; if the fitting is still not finished, the result has status "running", or "specs_ready" with the final specs and matched clubs while the written analysis is still being written. A failed fitting's result describes the free retry. Free; never starts or charges a fitting.

get_fitting

Ranks catalog clubs for one golfer with ELDRICK fit scores (0-100) and, for each club, a verdict, a short opinion, the reasons, how often ELDRICK picked it for similar golfers, and a suggested stock shaft. With a fittingId (any club type), that fitting's own matched picks rank first, in the fitting's order and with scores that follow it (97, 95, 93); other heads follow, scored from their catalog design and fitting evidence for similar golfers and always below the picks. The picks come from the fitting's product matcher, which checks the fitted specs and buildable shafts for each head; the other scores do not include that build check. Without a fitting it scores for a golfer described by driver speed and miss, e.g. golfer {"speed": 95, "miss": "slice"} (swingSpeed, missPattern and handedness are accepted too), or a preset, optionally for a goal and selected headIds. A wedge fitting returns its matched wedges without 0-100 scores. Free and deterministic; does not run or use a fitting.
