About the Subscriptions
User Registration
It may be required for you to register on the website. You commit to keep your password private and accept responsibility for any and all account activity. If we decide, in our sole discretion, that the username you choose is improper, objectionable, or otherwise unacceptable, we have the right to remove, reclaim, or replace it. If you share your password or API keys, you will be responsible for the consumption that your account has.
Free Trial
The Product may offer a 7-day free trial for consumers to test the API. When accessing the free trial, the consumer must register and enter their credit card information. At the end of the trial period, if the client did not previously cancel the subscription, Klazify Inc. will bill the amount corresponding to the subscription on a recurring basis until the consumer unsubscribes. Klazify Inc. will not accept refund requests for failure to cancel before the trial ends. It is important to clarify that the consumer will be able to access the free trial only once. If the consumer subscribes again in the future, they will not be eligible for another free trial.
Klazify Inc. reserves the right to discontinue the free trial or modify the trial period. The trial period will be announced on the website at the time of subscription. The consumer acknowledges and accepts that during the trial period they will not be able to claim any type of refund or compensation from Klazify Inc. The responses provided by the API during the free trial are licensed for personal and trial use only. They cannot be used for commercial purposes.
Subscription Period
Only a paid subscription is required to access the Service or certain portions of the Service. Depending on the type of subscription plan you choose when purchasing the subscription, you will be invoiced in advance on a recurring and periodic basis (such as monthly or annually). Unless you or the company decide to terminate it, your subscription will automatically renew at the end of each period under the same terms.
Fees and Payment
Payments are processed through Stripe (Visa, Amex, Mastercard, etc.). To access any of our paid subscriptions, you might need to make a purchase or pay a charge. For any purchases made through the Site, you promise to supply information that is up to date, complete, and accurate. You also consent to promptly updating your account and payment information, including your email address, payment method, and credit card expiration date.
Sales tax will be charged to the cost of purchases where required and will be additional to the prices shown in the pricing section. Prices are subject to change at any time. Every payment must be made in US dollars. You consent to paying all fees or charges at the rates in effect at the time of purchase. By subscribing, you agree to Stripe's Terms of Service.
Billing
You must provide Klazify Inc. complete and accurate billing information, including your full name, address, state, zip code, phone number, and information on a legitimate payment method. If for any reason automatic billing is unable to take place, Klazify Inc. will send you an electronic invoice informing you that you must manually make the entire payment corresponding to the billing period specified on the invoice by a specific deadline date. If you do not make the payment before the due date, Klazify Inc. will suspend access to the features and services included in the paid subscription and your account will lose API access.
Cancellation Policy
You can cancel your subscription at any time by logging into your web account. Your cancellation will be effective at the end of the current billing period, and any unused API calls and other features will not be refunded. Nor will a refund or credit note be made for unused days.
If you are having difficulty canceling your paid subscription via the website, please send an email to [email protected] from the email address you used to register your account. We will not accept a cancellation request from an email account different from the one used to register your account. Sending the email with the cancellation request does not mean that your account will be automatically canceled. You must wait for instructions or confirmation from our customer support team.
Service Support
Standard support services are included for all product plans Monday through Friday from 8 am to 5 pm EST via chat or email. If you require a more advanced level of support, you can contact us to acquire an Enterprise Plan.
Service Level Agreement
Klazify Inc. and its dedicated support team work hard to provide high-quality service that meets the needs of even the most demanding customers. All infrastructure is hosted in the cloud with top-of-the-line services that include backup and redundancy. In addition, all our services are monitored by an Operations Center capable of quickly identifying any type of failure and executing the planned contingency plans.
Despite all such efforts, you acknowledge that the Product may not be accessible for any reason related or not to Klazify Inc. and that refund requests related to service downtime will not be honored. If you need a custom service level agreement, please contact us to purchase an Enterprise Plan that meets your specific requirements.
API Response Accuracy
The Product replies to API queries with live information or with information stored in the database. It is understood that the Product collects sovereign bond yield data from several public and institutional sources, processes it, and returns the answer as accurately as possible. You understand and accept that the information may not always have the expected accuracy and that the lack of precision or the lack of data cannot be understood as a lack of service.
Bond yield data is for informational purposes only and should not be considered financial advice or a substitute for professional trading data. You also accept that you will not be able to make refund claims for this reason; however, you can report inaccuracies to the Customer Support team, who will escalate the issue to the Product Administrator to evaluate the improvements to be implemented.
About the API Calls
The API calls described in the Product refer to an API query. Queries made through the web interface are also considered an API call. It will be considered a successful API call whenever the success field in the response is equal to true. Any response with success equal to false will not be deducted from your monthly quota.
In the event that a customer repeatedly makes excessive and unsuccessful calls to the API, resulting in impaired server performance, Klazify Inc. reserves the right to take appropriate action, which may include deducting those calls or blocking access to the API. Such action may be implemented without prior notice. If the API query returns a true response but the information is inaccurate or incomplete, the API call will be deducted.
Usage Limits
The extent of your usage of the Product is dependent on your subscription plan. You shall not exceed the usage limits and rate limits associated with your account. Unused amounts of call usage will not be carried over from one monthly period to the next. If you exceed your monthly usage limit, the Product will return an error message stating that your monthly usage limit has been reached and no further API calls can be made within the current monthly term.
It is your sole responsibility to ensure that your application(s) properly detect and handle any returned error messages. Klazify Inc. will make reasonable efforts to help you identify and resolve usage problems, or to review the suitability of your current subscription plan for your needs. Klazify Inc. reserves the right to limit or throttle the number of network calls available to your application(s) if Klazify Inc. (in its sole discretion) believes that such calls are being made for malicious reasons, or as the result of a technical error.
Right to Change Content or Format
You acknowledge that Klazify Inc. may from time to time, and in its sole discretion, update or change the content or format of the Product data. Klazify Inc. shall strive to provide reasonable advance notification of such changes; however, from time to time sudden changes may be required, and since Klazify Inc. strives to accurately reflect market and data-source changes, significant advance notice is not always possible. You may be required to use the most recent version of the Product in order to ensure functionality of your application(s) with the Product.
Force Majeure
Klazify Inc. shall have no liability to the Customer under the Contract if it is prevented from or delayed in performing its obligations under the Contract, or from carrying on its business, by acts, events, omissions, or accidents beyond its reasonable control, including, without limitation, strikes, lock-outs or other industrial disputes, failure of a utility service or transport or telecommunications network, act of God, war, riot, civil commotion, malicious damage, compliance with any law or governmental order, rule, regulation or direction, accident, breakdown of plant or machinery, fire, flood, storm, or default of Klazify Inc. or sub-contractors, provided that the Customer is notified of such an event and its expected duration.
Publicity
By creating an account on the Product, you agree that Klazify Inc. may include your name and its trademarks in a list of customers for promotional purposes. Your name or your trademarks may be used in press releases, on the website, in newsletters, in business presentations with other prospects, and in any other promotional material that Klazify Inc. deems necessary. You may opt out of the provisions of this section by contacting Klazify Inc. and expressly requesting not to use your name or trademark for promotional purposes.

Refund Policy
Effective as of April 6, 2026
Refunds are valid within 2 hours after the time of purchase and only apply to the first payment the product receives, as long as the consumer has not made more than 10 API calls to the product.
If, for any reason, the payment for the subscription is doubled, only requests for a refund of the doubled payment will be accepted within 72 hours after the payment is confirmed. Refund requests for duplicate payments made in months earlier than the current month will not be accepted.
If the customer cancels its paid subscription on the website and, for any reason, the subscription cannot be canceled automatically in its Stripe account, claims will only be accepted within 72 hours of the cancellation made on the website. After this period, claims for refunds will not be accepted.
In the event that the customer subscribes to a free trial for a specific period but fails to unsubscribe before the trial period ends, we regret to inform you that refund requests will not be accepted under any circumstances.
If we determine that you are eligible for a refund, we will refund the full purchase price of your subscription. Please note that any third-party fees associated with your purchase, such as credit card processing fees, may not be refunded. Refunds will be processed within 14 business days of our approval.
Please note that our refund policy only applies to new customers who have purchased a subscription to our product. If you have previously received a refund for our product, you will not be eligible for another refund. Please understand that our refund policy is final, and we reserve the right to modify it at any time without notice.
To request a refund, the customer can send an email to [email protected] with their purchase information and explain why. The Customer Service team will analyze the claim and return a response. In the event that the refund request is accepted, we will issue refunds to the original payment method used to make the purchase.
