Last Updated: September 12, 2026 • Effective Date: September 12, 2026 ## 1. Acceptance of Terms & Legal Authority By accessing or using the APIs, developer portals, client SDKs, or websites provided by Stanza (“Stanza,” “we,” “us,” or “our”) at `stanzaapi.com` and related subdomains, you (“Customer,” “Developer,” or “You”) agree to be legally bound by these Terms of Service (“Terms”). If you are using the services on behalf of an organization, corporation, or entity, you represent and warrant that you possess full legal authority to bind that entity to these Terms. If you do not unconditionally agree to all terms and conditions herein, you must immediately cease accessing and using all Stanza APIs and services. ## 2. Pure-Compute Microservices & Zero Data Retention Architecture Stanza provides high-velocity algorithmic syntax parsing, format transformation, and check-digit validation microservices executed on serverless V8 isolates. Every transformation is engineered as a deterministic mathematical function (`f(x) = y`). - **Zero Retention:** Inbound transactional data exists exclusively in transient memory for the milliseconds required to compute transformations. No request or response bodies are persisted to disk, relational databases, or object storage. - **No Outbound Leakage:** Processing isolates do not initiate third-party outbound network calls during payload evaluation. - **Zero Payload Logging:** Edge access logs record only transport-level routing metadata (HTTP method, path, response status, latency, IP address); payloads and transaction bodies are completely excluded. ## 3. API Credentials, Quotas & Security Responsibilities Access to production endpoints requires an authenticated API key (prefixed `nk_live_`). You are solely responsible for maintaining the confidentiality of your API keys and for all activities, API requests, and financial charges incurred under your credentials. You agree to immediately notify Stanza at `support@stanzaapi.com` upon discovering any unauthorized disclosure or compromise of your API keys. Stanza reserves the right to immediately invalidate, rotate, or terminate any key suspected of compromise or abuse. ## 4. Strict Acceptable Use Policy & Prohibited Conduct You shall not, directly or indirectly: - Reverse-engineer, decompile, disassemble, or derive the source code or underlying algorithms of Stanza microservices; - Circumvent, bypass, or tamper with edge rate limits, authentication barriers, Turnstile bot verification, or quota caps; - Conduct denial-of-service (DDoS) attacks, automated scraping, vulnerability scanning, or Regular Expression Denial of Service (ReDoS) fuzzing against our edge network; - Share, sub-license, resell, or distribute API keys to third parties without prior express written consent; - Transmit any unlawful, infringing, libelous, defamatory, fraudulent, or malicious code or payloads. Violation of this Acceptable Use Policy results in immediate, permanent termination of access without notice, liability, or refund. ## 5. Statutory Disclaimers & Sector-Specific Safe Harbors **A. Healthcare EDI & HIPAA Notice (45 CFR § 164.514):** Public edge developer endpoints (ANSI X12 837P, 835, 270/271) are strictly for synthetic, test, or fully de-identified data. *The public edge is NOT certified for live electronic Protected Health Information (ePHI).* Processing live ePHI requires an executed Business Associate Agreement (BAA) and provisioning on our Enterprise HIPAA Plane. You agree to defend and indemnify Stanza against any regulatory fines, HHS investigations, or breach liabilities arising from your transmission of un-deidentified ePHI without an active BAA. **B. Financial Messaging Notice (ISO 20022, IBAN, LEI):** Microservices provide syntax verification and modulo checksum calculation only. Stanza is not a bank, depository institution, money transmitter, or SWIFT gateway. Outputs do not confirm account ownership, fund balances, or settlement status. **C. Pharmaceutical & Medical Device Serialization (21 U.S.C. § 360eee & FDA 21 CFR):** Barcode and GS1 AI parsing engines are informational syntax decoders and do not constitute an FDA-certified Verification Router Service (VRS) or certified regulatory repository. Customer retains sole statutory responsibility for drug and device supply chain compliance. **D. Tax, Customs & Environmental Regulation (EU VAT, Peppol, EU CBAM 2023/956):** Format validations and carbon emissions factor estimations do not substitute for certified fiscal auditing, tax advice, or official customs declarant filings. The declarant retains full legal liability under EU Article 26 and local tax codes. **E. Supply Chain & Maritime (ISO 6346, IATA Cargo):** Check-digit calculations and prefix lookups do not confirm physical possession, booking availability, tariff rates, or customs clearance of freight. ## 6. Subscriptions, Stripe Billing & Cancellation Services are billed in advance on recurring monthly or annual billing cycles through our merchant processor, **Stripe, Inc.** By subscribing to a paid tier (Pro, Ultra, Mega), you authorize automated recurring charges to your payment method. You may cancel your subscription at any time through our [Stripe Billing Portal](/api/stripe/portal). Cancellations take effect at the conclusion of your current paid billing period; no partial or prorated refunds are issued for unused quotas or mid-month cancellations. ## 7. Intellectual Property Stanza, its APIs, code libraries, SDKs, documentation, logos, and software architectures are the proprietary intellectual property of Stanza and its operators. Subject to compliance with these Terms, Stanza grants you a limited, revocable, non-exclusive, non-transferable license to access the APIs in accordance with your subscribed tier. You retain all right, title, and interest in your request payloads. ## 8. Disclaimer of Warranties (UCC § 2-316) TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES, APIS, SDks, AND DOCUMENTATION ARE PROVIDED STRICTLY ON AN “AS IS” AND “AS AVAILABLE” BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.

Comprehensive Indemnification You agree to defend, indemnify, and hold harmless Stanza, its affiliates, operators, officers, contractors, and licensors from and against any and all claims, damages, obligations, losses, liabilities, costs, debts, and legal expenses (including reasonable attorney’s fees) arising out of or resulting from: - Your access to, use of, or reliance upon the services or API outputs; - Your violation of any provision of these Terms or any applicable law, rule, or regulation; - Any live healthcare ePHI, financial data, or sensitive personal information transmitted by you in violation of Section 5; - Any third-party claim that your request payloads, data, or systems infringed or misappropriated any intellectual property, privacy, or proprietary rights. ## 11.

YOU EXPRESSLY WAIVE ANY RIGHT TO A TRIAL BY JURY. **D. One-Year Limitation:** Any claim or cause of action arising out of or related to these Terms or the services must be filed within one (1) year after such claim arose; otherwise, the claim is permanently barred. ## 12.

California Civil Code § 1542 Waiver:** You expressly waive all rights and benefits under California Civil Code Section 1542 (and any analogous statute of any other jurisdiction), which states: *“A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.”* **D. No Attorney Fee-Shifting:** Unless explicitly required by non-waivable statutory law, each party shall bear its own legal fees, expenses, and attorney costs.
