Access to the Paid Services using VPN software or any other privacy or anonymization tools or techniques to circumvent, or attempt to circumvent, any restrictions that apply to the Paid Services, is prohibited.

Enterprise plans may also be governed by an Order Form. No service level, uptime commitment or support-response time applies unless stated in an Order Form signed by the Company. Starkscan meters usage in Credits rather than treating every request as equal; different API or RPC methods may consume different numbers of Credits based on their expected compute, storage, indexing, data volume or operational cost, and batch requests may be metered per item rather than as a single request. Changes to plans, prices, Credit weights or limits apply prospectively and shall not retroactively affect Credits already granted and shall be published on the Site from time to time. Users are advised to check the Pricing Page regularly. Continued use of the Paid Services following the posting of an updated version of the Pricing Page shall constitute acceptance of the updated Credit Weights therein.

Credits may only be used for the Paid Services, are non-transferable, and are non-redeemable for cash or any crypto or virtual asset, and do not bear interest. Credits granted under a Subscription reset at the start of each billing period and do not carry over unless stated on the Pricing Page or an Order Form. Credits added through a Token Top-Up expire twelve (12) months after the date they are credited to the Account, with the oldest Credits applied first. Accounts located in, or treated as located in, the United States are subject to a daily maximum Token Top-Up limit equivalent to US$2,000. Use of VPN software or any other privacy or anonymisation tool to circumvent, or attempt to circumvent, the above restrictions is prohibited.

Subscriptions are processed by Paddle as merchant of record and reseller and renew automatically for successive billing periods until cancelled. Paddle handles payment collection, applicable transaction taxes, receipts, cancellations and any approved refunds in connection with Paddle Transactions, in accordance with Paddle’s buyer terms.

Token Top-Ups are available only where offered on the Pricing Page and must be made using the approved Supported Tokens, on the approved network, in the approved amount, and through the Company’s screened-wallet flow then in effect. Payment instructions will be provided, and Credits added, only after required location, has been completed and approved.

Refunds related to Paddle Transactions shall be processed by Paddle pursuant to Paddle’s Refund Policy at https://www.paddle.com/legal/refund-policy.

For amounts paid directly to the Company, you are responsible for all sales, use, ad valorem and excise taxes, value added, and any other similar taxes, duties and charges of any kind imposed on those amounts, other than taxes on the Company’s income. This does not apply to taxes collected and remitted by Paddle as merchant of record for Paddle Transactions. In the event that you are required to deduct or withhold any taxes from the amounts payable to the Company hereunder, you will pay an additional amount, so that the Company receives the amounts due to it in full, as if there were no withholding or deduction.

Subject to the user's continued compliance with these Terms, the Company grants to the user the right to access and use the Paid Services. Notwithstanding the foregoing, the user acknowledges and agrees that all Intellectual Property held or pertaining to the Paidx Services, including text, documents, descriptions, trade marks, software, graphics, interactive elements and Feedback (collectively, "Content"), are the property of the Company and/or its licensors and are protected by applicable copyright and intellectual property laws.

The Company may, at its own expense, issue a mutually approved press release regarding the user's use of the Paid Services.

The user shall be solely liable for: all authorised and unauthorised access, damage, or loss arising through the use or misuse of its hardware, software or the Paid Services. For the avoidance of doubt, this liability extends to use of the Paid Services by agents, tools and integrations, regardless of whether they are authorised by the user or not.

All applicable API rate limits are shown on the Site dashboard, Documentation, response headers, or any separate written agreement applicable to your use of the Paid Services.

Notwithstanding the foregoing or anything contained in these Terms, nothing herein prevents the user from storing, processing, displaying or integrating public blockchain data and API outputs obtained through permitted use of the Paid Services into its own products and workflows. The user may not copy, resell, sublicense or provide access to the Paid Services themselves or reproduce the Company’s proprietary software, interfaces or datasets except as expressly permitted herein.

Paid Services log-in credentials and API keys issued by the Company are for the user's use only and may not be sold, transferred, or sublicensed save to Authorised Users, agents, tools, integrations or subcontractors acting on the user's behalf. The user shall employ all reasonable security measures (including multi-factor authentication) to protect such credentials and shall notify the Company immediately upon becoming aware that any credential may have been compromised.

5.3 User Representations & Warranties

The user hereby represents and warrants that any and all wallets which it connects or uses in connection with the Paid Services are legally and/or beneficially owned and/or controlled by the user and that the user is not acting as nominee for any other person, entity or arrangement. In addition, the user hereby represents and warrants that neither the user, its Affiliates nor any of its officers or employees: (i) was or is the subject or target of any sanctions; or (ii) has breached, is currently breaching and/or will breach any anti-corruption laws and/or anti-money laundering laws.

The Paid Services and any third-party content, websites or services accessible via the Paid Services are provided on an “as is” and “as available” basis. To the fullest extent permitted by law, the Company: (i) makes no representations or warranties of any kind, whether express, implied, statutory, or otherwise, in relation to the Paid Services, third-party content, websites or services; and (ii) disclaims all warranties, including any implied warranties of merchantability, satisfactory quality, fitness for a particular purpose, non-infringement, and quiet enjoyment; any warranty arising from course of dealing or usage of trade; any warranty that the Paid Services, third-party content, websites or services, internet, or blockchain networks will operate without interruption or error; and any warranty as to the accuracy, completeness, availability, or security of any content, data or information. The Paid Services have not been developed or tailored to meet the user’s individual requirements, including any cybersecurity specifications you may be subject to under law or otherwise. The user downloads or obtains any materials, including third-party content through the Paid Services entirely at its own risk.

The data displayed pursuant to the Paid Services is for informational purposes only and should not be interpreted as an endorsement, recommendation or financial or investment advice of any kind.

For the avoidance of doubt, where enabled, a user or the user’s wallet or application creates and signs a Starknet transaction outside the Paid Services via an independent service provider. The Paid Services forward the already-signed payload to configured RPC infrastructure and return the upstream response. The Company does not create, modify, sign, custody or determine the contents of the transaction, and submission does not guarantee acceptance, inclusion, confirmation or finality. In no circumstances will either the Paid Services or the Company:

(i) custody any digital, virtual or crypto asset(s);

(ii) execute blockchain or any other form of transactions on behalf of users;

(iii) hold or custody user keys;

(iv) sign transactions;

(v) become a party to transactions relayed via the Paid Services; or

(vi) be a party to users’ smart-contract interactions.

The user acknowledges that digital and crypto assets are subject to significant market volatility and that the cost and speed of blockchain networks are variable and beyond the Company's control. The user assumes sole responsibility for all risks associated with its use of the Paid Services in connection with blockchain networks.

To the fullest extent permitted by law, the user shall defend, indemnify, and hold harmless the Company and its Affiliates, licensors, and each of their respective officers, directors, employees, and representatives against all Losses arising from or relating to: (i) the user's use of or access to the Paid Services; (ii) the user's breach of these Terms; and (iii) a violation of applicable law.

The Company does not store private keys or seed phrases. Furthermore, the user is solely responsible for implementing and maintaining appropriate security measures to safeguard the wallet(s) connected to or used in connection with the Paid Services, including the protection of any private keys, passwords, or other credentials necessary to access the wallet(s). The Company bears no liability for any loss, theft, or unauthorised access resulting from the user’s failure to secure their wallet or associated credentials.

The Company may assign these Terms at any time to (i) an Affiliate or (ii) a successor in connection with a merger, acquisition, or sale of all or substantially all of the Company’s assets.

The user shall comply with all applicable laws, decrees, rules or regulations in effect in the jurisdiction of either of the Company or the user, including those relating to import, export, re-export, and anti-boycott. The user, the user’s Affiliates and any persons acting on user’s or user’s Affiliates’ behalf have complied, at all times with all laws, statutes and regulations relating to anti-money laundering, countering the financing of terrorism, sanctions, anti-bribery and anti-corruption under all laws applicable to it or them (as the case may be). The user is solely responsible for compliance as regards the manner in which it uses the Paid Services.

Notices to the Company shall be given by email to [email protected].

No failure by the Company to enforce any provision of these Terms shall be construed as a waiver or limitation of the Company’s right to subsequently enforce and compel strict compliance with such provision or any other provision of the Terms. The Company shall not be deemed to have waived any claim arising out of the Terms, or any provision, power, right, privilege or remedy under the Terms, unless the waiver is expressly set forth in writing by the Company; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

These Terms are severable. If any term is held to be invalid or unenforceable for any reason, the remaining terms will continue to be valid and enforceable. If a court finds that any term is invalid or unenforceable, but that by limiting such term it would become valid and enforceable, then such term will be deemed to be written, construed, and enforced as so limited.

These Terms shall be governed by and construed in accordance with the laws of the Cayman Islands, without giving effect to any conflict of law principles and the Parties agree that the courts of the Cayman Islands shall have exclusive jurisdiction over any dispute or issue arising out of these Terms.
