8.3 Email-specific rules. Without limiting the above, the Client shall not send emails from generic group addresses (e.g., hello@, marketing@), use a fictional identity, omit required opt-out mechanisms, or generate an unacceptable level of bounces, spam or complaints.

8.5 Notice of violation. If the Client becomes aware of or suspects a violation, it shall notify BlitzAPI. BlitzAPI may reasonably determine compliance and may immediately suspend, block or terminate the Account for any breach of this Section 8, without refund, in addition to any other remedy.

9. Fair Use Policy & Rate Limits

9.1 Each Plan is subject to a Fair Use Policy consisting of (i) a maximum monthly volume of Records (“Data Infra / Fair Use Policy”) and (ii) a maximum request rate (requests per second, “RPS”). Unless otherwise stated in an Order Form, the following limits apply to Plans subscribed under the launch offer described in Section 10.7:

Plan RPS Data Infra / Fair Use Policy (Records / month)
Core 50 15,000,000
Plus 50 15,000,000
Full 50 15,000,000

Plans differ by the categories of Data included, as stated on the website at the time of subscription: Core includes all Data categories except verified email addresses and phone numbers; Plus adds verified email addresses; Full includes all Data categories, including phone numbers. For Plans offered after the launch offer closes, the applicable limits and Data categories are those stated on the website or in the Order Form at the time of subscription.

9.2 Records are counted per Result returned by the Services. The monthly Fair Use volume resets at the start of each monthly billing cycle and, unless expressly agreed otherwise, unused Records do not carry over.

9.3 Exceeding the Fair Use limit. If the Client reaches its monthly Fair Use volume, BlitzAPI may throttle or automatically block further calls (deactivation of the API key and/or access limitation) until the start of the next monthly cycle, unless a higher allowance or a custom setup is agreed with BlitzAPI. BlitzAPI assesses sustained usage over time and will normally contact the Client to agree on a suitable setup before applying such measures; immediate measures remain available in the situations described in Section 9.4.

9.4 Anti-abuse. “Fair use” excludes abusive patterns, including stress tests, denial-of-service-like traffic, circumvention of throttling, or opening multiple Accounts to bypass Plan limits. BlitzAPI may apply reasonable technical measures (queuing, batching, temporary limits) to protect the stability of the Services, and may suspend Accounts engaged in abuse.

9.5 BlitzAPI may offer a free trial with a limited allowance (such as a one-time credit allowance, as stated on our website); certain Data categories or endpoints may be excluded from the trial. Free access is subject to these Terms and may be modified or withdrawn at any time.

10. Plans, Fees & Payment

10.1 Plans are monthly or annual, prepaid. Annual Plans are payable in full upfront. Fees are stated exclusive of tax.

10.2 Payment. Fees are payable in advance via the payment method on file (e.g., Stripe). By subscribing, the Client authorizes recurring charges for each renewal period.

10.3 Renewal. Subscriptions renew automatically for successive periods equal to the initial period, at the then-current price, unless cancelled: for monthly Plans, before the next renewal date; for annual Plans, with the notice stated in the Order Form (and at least 30 days before the end of the term).

10.4 Late payment. In the event of non-payment, failure, rejection or chargeback, BlitzAPI may suspend or block access (deactivation of the API key) until full regularization. Overdue amounts may bear interest at the maximum rate permitted by applicable law, plus reasonable collection costs.

10.5 Taxes. The Client bears all applicable taxes (including any withholding), other than taxes on BlitzAPI’s net income. If a withholding is imposed, the Client shall gross-up so that BlitzAPI receives the agreed net amount, save where legally prohibited.

10.6 No refund. Except where required by law, all fees are non-cancelable during the term and non-refundable, including for partially used Services. Any free credits or allowances are non-transferable and non-refundable.

10.7 Launch offer (lifetime terms). For Accounts whose first subscription to a Plan takes effect on or before September 30, 2026, the monthly fee, rate limit and Fair Use Policy applicable at the time of subscription remain in force for as long as the subscription remains active and uninterrupted, notwithstanding the “then-current price” renewal mechanics of Section 10.3. Changing Plans within the launch offer keeps these terms on the new Plan. These terms lapse automatically upon cancellation, non-renewal, lapse or termination of the subscription for any reason, and do not revive upon re-subscription; they are personal to the Account and non-transferable. This Section does not limit BlitzAPI’s rights under Sections 9.4 and 11.

11. Suspension & Termination

11.1 Termination for cause. Either Party may terminate the Contract if the other Party materially breaches these Terms and fails to cure within fifteen (15) days of written notice (ten (10) days for non-payment). BlitzAPI may suspend, block or terminate immediately and without notice in case of: prohibited resale or redistribution (Section 6); prohibited or abusive use (Sections 7–9); unlawful use; or where required to protect the Services or comply with law.

11.2 Effect of termination. Upon expiry or termination: the Client’s rights cease and it must stop all access to and use of the Services and API keys. The Client may retain Data lawfully obtained during the subscription for its own internal business use only, subject to Sections 5, 6 and 14, but may not resell, redistribute or create derivative works from it.

11.3 No refund will be made for the current period on termination or suspension for cause.

11.4 Survival. Sections 5.2, 6, 8, 12, 13, 14, 16, 17, 18, 22 and 23, and any accrued payment obligations, survive termination.

12. Confidentiality

12.1 Each Party (the “Receiving Party”) shall protect the non-public, proprietary or confidential information of the other (the “Disclosing Party”), including pricing, Documentation, endpoints, API keys and performance data, with at least a reasonable degree of care, use it only to exercise its rights or perform its obligations, and not disclose it except to its representatives bound by confidentiality. The Data constitutes BlitzAPI’s Confidential Information.

12.2 Confidential Information excludes information that is or becomes public without breach, is lawfully received from a third party, was already known, or is independently developed. A Party may disclose Confidential Information where required by law, using reasonable efforts to notify the other Party in advance.

13. Data Protection & Compliance

13.1 BlitzAPI processes personal data in accordance with applicable data-protection laws (including the GDPR). The DPA is incorporated into these Terms by reference and governs the processing of personal data in connection with the Services.

13.2 BlitzAPI processes only the Client’s account and billing information for contract execution, support, and internal marketing. BlitzAPI does not use Client-provided data to enrich its own database, and does not sell Client data to third parties.

13.3 Independent controllers. Except as otherwise stated in the DPA, each Party acts as an independent controller for its own purposes. The Client is solely responsible for its downstream use of the Data, for maintaining a valid legal basis, providing required information, and honouring data-subject rights.

13.4 The Client shall comply with all applicable data-protection laws and the terms of source platforms (e.g., LinkedIn).

14. Intellectual Property

14.2 The Client may keep Data obtained during the subscription for its own internal business use after expiration, but may not resell, redistribute, sublicense, or create derivative works from it, nor make it available to any third party.

14.3 The BlitzAPI names and logos are trademarks of BlitzAPI and may not be used without prior written permission. Any feedback provided by the Client that is incorporated into the Services is owned by BlitzAPI.

15. Representations, Warranties & Disclaimer

15.1 Mutual warranties. Each Party represents that it is duly organized and authorized to enter into these Terms, and that it will comply with all applicable laws in connection with its rights and obligations.

15.2 Disclaimer. Except as expressly stated, the Services and Data are provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, title, non-infringement, or accuracy, completeness, currency or deliverability of Data. Data is compiled from third-party sources and may contain errors or omissions. The Client’s use of and reliance on the Data is at its own risk, and the Client is solely responsible for verifying accuracy and legal compliance before acting on it. Some jurisdictions do not allow certain disclaimers; these apply to the fullest extent permitted by law.

16. Indemnification

16.1 By the Client. The Client shall indemnify, defend and hold harmless BlitzAPI, its affiliates, officers, employees and service providers from any third-party claim arising out of or in connection with: (i) the Client’s use of the Services or Data; (ii) the Client’s breach of these Terms; (iii) the Client’s violation of any applicable law or third-party right (including spam, GDPR, privacy or IP claims); or (iv) data or content provided by the Client.

17.2 Cap. Except as set out below, each Party’s total aggregate liability under these Terms shall not exceed the amounts paid by the Client to BlitzAPI during the twelve (12) months preceding the event giving rise to the claim.

17.3 Carve-outs. The exclusions and cap in this Section do not apply to: the Client’s breach of Sections 6, 7 or 8; the Client’s payment or indemnification obligations; a Party’s fraud, gross negligence or willful misconduct; or breach of confidentiality (Section 12).

17.4 Basis of the bargain. The Parties acknowledge that the pricing of the Services reflects these limitations of liability, and that without them the fees would be significantly higher.

18. Equitable & Injunctive Relief

18.1 In the event of a breach of Section 6 (resale/redistribution), Section 12 (confidentiality), or Section 14 (intellectual property), the Client agrees that monetary damages may be inadequate and that BlitzAPI is entitled, in addition to any other remedy (including monetary remedies), to seek specific performance and injunctive or other equitable relief, including disgorgement of profits derived from the breach.

18.2 The Client waives any requirement that BlitzAPI post a bond in connection with such relief. Should BlitzAPI prevail in an action asserting a breach of Section 6, the Client shall pay BlitzAPI’s reasonable attorneys’ fees and costs, including costs of investigation.
