Effective date: November 13, 2026.
Agreement
These terms are a contract between Arc Gnomon LLC ("Arc Gnomon", "we", "us") and the person or organization that creates a GolfAPI.dev account or uses the GolfAPI.dev API, website or dashboard ("you"). "GolfAPI.dev" means the GolfAPI.dev API, the golfapi.dev website, the dashboard at console.golfapi.dev, the catalog they serve and the related documentation. These terms cover free and paid accounts. The Data license and the Privacy notice form part of these terms.
You accept these terms when you check the acceptance box at checkout, start a subscription or use an API key. If you do not agree, do not use GolfAPI.dev.
If you accept for an organization, you confirm that you have authority to bind it, and "you" means that organization. You must be at least 18. Hobby is for personal and non-commercial use. Pro and Enterprise are for business use.
Seller and contact
GolfAPI.dev is operated by Arc Gnomon LLC, 429 Kent Avenue, Brooklyn, NY 11249. Contact hello@golfapi.dev for billing, support, refunds or account closure. Send legal notices to legal@golfapi.dev. We send notices to your account email address, and a notice is received when sent.
The service
GolfAPI.dev provides read-only access to its published golf club catalog. The plans are Free, Hobby and Pro. Hobby is for personal and non-commercial use; commercial use needs Pro. Enterprise is available only under a written agreement signed by Arc Gnomon. Your plan determines the resources, data views, request limits and number of active API keys available to your account. The plan information shown at checkout describes the plan at the time of purchase. Features marked coming soon are not included in that purchase.
The catalog changes. We may add, correct, reclassify or remove records, fields, resources and views at any time, and may change or discontinue features of the service. If we discontinue a paid plan, or remove a resource included in your paid plan, we will email you at least 30 days in advance where practical. You may then cancel and receive a pro-rata refund of fees prepaid for the period after the change.
Free access is limited to sandbox keys and the sandbox sample, for testing, integration development and personal, non-commercial use. We may change, limit or end free access at any time.
Paid plans include email support. There is no uptime, availability or support-response commitment unless a separate written agreement signed by Arc Gnomon provides one. The service may be unavailable for maintenance, provider outages or reasons outside our control.
Billing and renewal
Subscriptions are billed monthly in advance in USD and renew automatically until canceled. Checkout shows the recurring price before you subscribe. Stripe processes payments and provides invoices and payment-method management. You authorize the recurring charges described at checkout.
Fees exclude taxes. You are responsible for sales, use, value-added and similar taxes on your purchase, other than taxes on our income.
Upgrades are prorated. Downgrades and cancellations take effect at the end of the current billing period. The billing portal shows the effective date and charge before you confirm a change. An upgrade does not promise a fresh request allowance or reset usage already recorded.
There are no automatic overage charges. Requests above a rate or request allowance are rejected until the applicable limit resets or your access changes. Test and live keys share the account's monthly request allowance.
If a payment fails, we may retry the charge and may suspend paid access, or move the account to the Free plan, until the balance is paid.
We will email you at least 30 days before a price change takes effect. A price change applies from your next renewal after that notice, not to a period already paid for. You can cancel before that renewal.
Cancellation
Sign in at https://console.golfapi.dev/ and open billing management to cancel before the next renewal. Cancellation stops future renewals, and paid access continues until the end of the current paid period unless the account is suspended or closed. If you cannot use billing management, contact hello@golfapi.dev for help. Cancellation does not close your account or delete its records.
Refunds
Fees are non-refundable except as stated in these terms or required by law. Email hello@golfapi.dev from your account address with the charge date, amount and reason for a refund request. Do not send an API key or payment-card details.
We do not refund cancellation, unused requests or unused time. We review billing errors and cases where purchased access was not provided, and decide those refunds at our discretion. Any refund required by applicable law remains available. A refund does not by itself cancel a subscription; confirm cancellation separately if you also want to stop renewal.
Acceptable use
You are responsible for all activity under your account and API keys. Keep API secrets on your server and revoke compromised keys promptly.
You may not:
- share your account or API credentials outside your organization;
- bypass or avoid request limits, quotas or entitlements, including by opening multiple accounts;
- probe, scan or test the security of the service without our written permission, or interfere with its operation;
- scrape golfapi.dev or extract catalog data other than through the API within your plan;
- reverse engineer the service, except to the extent applicable law allows despite this restriction;
- use the service or catalog data in violation of law or the Data license; or
- use the service if you are located in a country subject to comprehensive US sanctions or are listed on a US government restricted-party list.
Your applications and end users
You are responsible for your applications, your end users and the way your applications present catalog data, including compliance with advertising, pricing and consumer-protection laws. A launch price (intro_price) is a historical US launch MSRP. Do not present it as a current price, a retailer's price or an offer. Do not state or imply that Arc Gnomon or a manufacturer endorses your product.
Suspension and termination
We may suspend access immediately, without prior notice, for compromised credentials, a security risk, abuse, nonpayment, a legal requirement or a violation of these terms. We will tell you the reason when we can, unless law or security prevents it.
We may terminate your account or these terms for a material or repeated violation, or if we stop offering GolfAPI.dev. If we terminate for a reason other than your violation, we refund fees prepaid for the period after termination.
To close an account, email from the account address. We confirm the request, cancel any subscription and disable the account's keys. Personal-data deletion is handled separately under the Privacy notice.
Terms that by their nature should continue after termination survive it, including fees owed, the Data license's duties after access ends, ownership, disclaimers, limitation of liability, indemnity and disputes.
Ownership and feedback
Arc Gnomon and its licensors own the service, the catalog and its selection, arrangement and compilation, the documentation, and the GolfAPI.dev names and marks. You receive only the rights these terms and the Data license expressly grant. All other rights are reserved.
If you send suggestions or feedback, we may use them for any purpose without obligation to you.
Disclaimers
THE SERVICE AND THE CATALOG DATA ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT ALLOWED BY LAW, ARC GNOMON DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, AVAILABILITY AND UNINTERRUPTED OR ERROR-FREE OPERATION.
The catalog is incomplete and may contain errors. A missing value is unknown, not zero or false. Catalog data is not fitting, safety or purchasing advice. You are responsible for checking catalog data before you rely on it or show it to others.
Limitation of liability
TO THE FULLEST EXTENT ALLOWED BY LAW:
(a) ARC GNOMON IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, BUSINESS, GOODWILL OR DATA, EVEN IF ADVISED THAT THEY WERE POSSIBLE; AND
(b) ARC GNOMON'S TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATING TO THE SERVICE, THE CATALOG DATA OR THESE TERMS IS LIMITED TO THE GREATER OF THE FEES YOU PAID ARC GNOMON IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, AND USD 100.
These limits apply to every theory of liability, including contract, tort (including negligence) and statute, and apply even if a limited remedy fails of its essential purpose. They do not limit liability that applicable law does not allow to be limited.
You agree to bring any claim relating to GolfAPI.dev only against Arc Gnomon LLC, and not against its members, managers, officers, employees or contractors individually.
Indemnity
You will defend and indemnify Arc Gnomon and its members, managers, officers, employees and contractors against any third-party claim, and the resulting losses, damages, fines, settlements and reasonable attorneys' fees, arising from your applications, your end users' use of them, your use or display of catalog data, your breach of these terms or the Data license, or your violation of law or third-party rights.
We will notify you of the claim, let you control its defense and cooperate at your expense. You may not settle a claim in a way that imposes an obligation or admission on us without our written consent.
Disputes
New York law governs these terms and any dispute relating to GolfAPI.dev, without regard to conflict-of-laws rules. The state and federal courts located in New York County, New York have exclusive jurisdiction, and both parties consent to them. Arc Gnomon may seek injunctive relief in any court of competent jurisdiction to protect the catalog, its intellectual property or the service.
EACH PARTY WAIVES ANY RIGHT TO A JURY TRIAL. To the extent the law allows, claims may be brought only individually and not as a plaintiff or class member in a class, collective or representative proceeding.
A claim must be brought within one year after it arises, or it is barred.
Changes to these terms
We may change these terms. We will email account holders at least 30 days before a material change takes effect, except a change required by law or for security, which may take effect sooner. If you continue to use GolfAPI.dev after a change takes effect, you accept it. If you do not agree, cancel before the effective date. A change does not apply retroactively to a period already paid for.
General
These terms, the Data license, the Privacy notice and any order form or written agreement signed by Arc Gnomon are the entire agreement about GolfAPI.dev. A signed written agreement controls over these terms where they conflict; the Data license controls on the use of catalog data.
You may not assign these terms without our written consent. We may assign them as part of a merger, acquisition, reorganization or sale of assets. Neither party is liable for delay or failure caused by events beyond its reasonable control. If a provision is unenforceable, it is enforced to the maximum extent allowed and the rest remains in effect. Our failure to enforce a provision is not a waiver. The parties are independent contractors. You consent to receiving agreements, notices and other communications electronically.
