1Shot API Terms of Service

These Terms of Service ("Terms") govern your access to and use of the website at https://www.1shotapi.com and all related APIs, SDKs, tools, documentation, and services (collectively, the "Service") operated by 1Shot API, Inc. ("1Shot API", "we", "us", or "our").

By creating an account, integrating our APIs, or otherwise using the Service, you agree to be bound by these Terms. If you are using the Service on behalf of a company or other legal entity, you represent that you have authority to bind that entity, in which case "you" and "your" refer to that entity. If you do not agree to these Terms, do not use the Service.

Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will update the "Effective Date" at the top of these Terms and, where appropriate, provide additional notice (for example, by email or an in-product message). Unless otherwise stated, the updated Terms will take effect immediately upon posting. These Terms replace prior versions. If you used the Service before the Effective Date, the prior Terms applied until this version became effective. By continuing to access or use the Service after the updated Terms become effective, you agree to be bound by the updated Terms. If you do not agree to the updated Terms, you must stop using the Service.

1. Service Overview

1.1 What 1Shot API Does

1Shot API is a developer platform for onchain automation. It turns smart contract functions into production-ready API endpoints so you can:

• Read data from EVM-compatible smart contracts
• Encode, simulate, and estimate gas for contract calls
• Execute contract methods and batches on supported networks
• Use managed wallets / smart accounts to send stablecoin and other onchain payments
• Trigger and react to blockchain events via webhooks and workflow tools (e.g., n8n, Make, IFTTT, etc.)

1.2 Non-Custodial Infrastructure

1Shot API provides technical infrastructure and orchestration. We:

• do not operate a centralized exchange or marketplace;
• do not hold user deposits in omnibus accounts; and
• do not act as your broker, dealer, investment adviser, or money transmitter.

Where we operate or manage wallets or smart accounts on your behalf, we do so purely as a technical service provider, and you remain responsible for how those wallets are funded and used.

1.3 No Control Over Blockchains

We do not control public blockchains, smart contracts, or protocols you interact with. We cannot:

• guarantee that any transaction will be included in a block;
• reverse or modify transactions; or
• guarantee any particular behavior of a chain, token, or protocol.

You are responsible for selecting contracts, parameters, and networks, and for reviewing all transactions before you submit or approve them.

1.4 1ShotPay; Supplemental Terms

1Shot API may also offer a payment initiation product branded as 1ShotPay, including paylinks, QR codes, and payment initiation pages and related APIs ("1ShotPay"). If you access or use 1ShotPay, your use of 1ShotPay is governed by the 1ShotPay Terms of Service ("1ShotPay Terms"), which supplement these Terms and are incorporated by reference. If there is any conflict between the 1ShotPay Terms and these Terms with respect to 1ShotPay, the 1ShotPay Terms control.

4. License and Use of the Service

4.1 License

Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable license to access and use the Service and integrate the APIs into your applications, workflows, or agents solely for your internal business purposes or as otherwise expressly permitted in your plan or order form.

4.2 API Credentials

You must:

• keep API Credentials secure and confidential;
• not embed them in client-side code, mobile apps, or public repositories;
• not share them with any third party except as strictly necessary to operate your own services; and
• promptly revoke or rotate keys if they may have been compromised.

We may revoke or rotate API Credentials if reasonably necessary to protect the Service, other users, or comply with law.

4.3 Usage & Rate Limits

Your use of the Service may be subject to plan-based usage limits (e.g., requests per month, number of wallets, workflows, or transactions) and rate limits (e.g., requests per second). We may monitor usage and enforce these limits by throttling, temporary suspension, or requiring you to upgrade your plan.

4.4 Reservation of Rights

Except as expressly granted in these Terms, we and our licensors reserve all rights, title, and interest in and to the Service, including all software, APIs, interfaces, Documentation, designs, and underlying technology.

5. Blockchain Transactions and Wallets

5.1 Irreversible Transactions

Blockchain transactions are typically irreversible once broadcast and included in a block. You are solely responsible for:

• verifying recipient addresses, contract addresses, function selectors, parameters, and network choices;
• reviewing any transaction previews, simulations, or gas estimates; and
• confirming that you are willing to bear the gas fees, protocol fees, and potential losses associated with each transaction.

5.2 Managed Wallets / Smart Accounts

If you use 1Shot API-managed wallets or smart accounts:

• they may be created, configured, and orchestrated by us, but are intended for non-custodial use;
• you remain responsible for funding those accounts and for all transactions executed from them;
• you must not share any recovery mechanism, signing authority, or credentials with unauthorized parties.

For 1Shot API-managed wallets or smart accounts, you instruct us to generate and hold the cryptographic keys or other signing material necessary to operate those wallets solely so that we can sign and relay transactions that you or your integrations initiate. We will apply commercially reasonable safeguards to protect such keys in accordance with Section 11.3, but you understand that digital assets associated with those wallets remain on public blockchains and are not held by us in omnibus or custodial accounts.

5.3 No Contract Review or Endorsement

We do not audit or review smart contracts or tokens you interact with, and we do not endorse any particular protocol, token, or onchain strategy. Any annotations, prompts, or labels we provide are for developer convenience only and do not constitute security audits, legal advice, financial advice, or investment recommendations.

5.4 Digital Assets and Stablecoins (Including USDC)

The Service may facilitate transactions involving digital assets, including stablecoins such as USDC and other supported tokens. Digital assets are not legal tender, are not bank deposits, and are not insured by the FDIC, SIPC, or any similar protections. Even "stablecoins" may lose value, become illiquid, or deviate from their intended peg due to market conditions, issuer actions, smart contract features, regulatory actions, or other risks.

Some tokens and smart contracts may include features that can restrict, freeze, block, claw back, or otherwise affect transfers. Such features are determined by token issuers and smart contract code and are outside of 1Shot API's control. 1Shot API does not issue digital assets and does not guarantee any asset's value, redemption, availability, or 1:1 peg.

You are solely responsible for evaluating digital asset risks and for determining and satisfying any tax or reporting obligations arising from your use of the Service.

5.5 Supported Networks and Assets May Change

Supported networks, tokens, and features may change over time. We may add, remove, or modify supported networks, token support, or functionality at any time, including for legal, technical, security, or liquidity reasons. You are responsible for verifying support before building or relying on a given network, token, or feature.

6. Your Responsibilities

You are solely responsible for:

• the design and operation of your applications, workflows, agents, and automations that use the Service;
• selecting which contracts, chains, tokens, and counterparties to interact with;
• complying with all applicable laws, regulations, and industry rules (including financial, consumer protection, AML/CTF, sanctions, and privacy laws) in each jurisdiction where you and your End Users are located;
• providing any required notices and obtaining any required consents from End Users.

You must ensure your End Users are bound by terms that are at least as protective of 1Shot API as these Terms.

7. End Users

• all transactions that you or your End Users initiate, approve, or interact with; and
• providing any required disclosures, obtaining any required consents, and handling any complaints or disputes with End Users.

7.2 No Liability to End Users

1Shot API has no obligation or liability to any End User, and our obligations under these Terms are owed only to you. Your obligations or liability to any End User will not increase or expand 1Shot API's obligations or liability under these Terms.

These Terms and any dispute, claim, or controversy arising out of or relating to them or the Service (collectively, "Disputes") are governed by the laws of the State of Delaware, without regard to its conflict-of-laws principles, except that the U.S. Federal Arbitration Act governs the interpretation and enforcement of this Section 19.

19.2 Agreement to Arbitrate

Except as expressly provided in Section 19.3 (Exceptions) below, you and 1Shot API agree that any Dispute between you and us will be resolved exclusively by binding, individual arbitration.

You and 1Shot API each waive the right to a trial in court (including a jury trial) and the right to have any Dispute resolved by a judge or jury.

19.3 Exceptions (Injunctive Relief and Small Claims)

This agreement to arbitrate does not apply to:

• individual claims that may be brought in small claims court if they qualify; and
• either party's right to seek temporary or preliminary injunctive or other equitable relief in any court of competent jurisdiction, in order to prevent or stop actual or threatened infringement, misappropriation, or violation of that party's intellectual property rights or Confidential Information, or to preserve the status quo pending arbitration.

19.4 Arbitration Rules and Process

The arbitration will be administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules and, where applicable, its Supplementary Procedures for Consumer-Related Disputes (collectively, the "AAA Rules"), as modified by these Terms. The arbitration will be conducted by a single arbitrator. Unless you and 1Shot API agree otherwise, the seat and place of arbitration will be San Francisco, California, U.S.A., and the arbitration may be conducted in person, by video conference, or by other remote means as the arbitrator deems appropriate. The language of the arbitration will be English. The arbitrator has the authority to grant any relief that would be available in court under law or in equity, consistent with these Terms, and the award shall be final and binding on you and 1Shot API. Judgment on the arbitral award may be entered and enforced in any court of competent jurisdiction.

19.5 Class Action and Representative Action Waiver

To the maximum extent permitted by law, you and 1Shot API agree that:

• any arbitration or court proceeding will be conducted only on an individual basis; and

The arbitrator may not consolidate more than one person's or entity's claims or otherwise preside over any form of representative or class proceeding.

19.6 Time Limit to Bring Claims

To the fullest extent permitted by law, you and 1Shot API agree that any Dispute (other than 1Shot API's claims for infringement, misappropriation, or violation of 1Shot API's intellectual property rights or Confidential Information) must be filed within one (1) year after the cause of action arose; otherwise, the claim is permanently barred.

You may not assign or transfer these Terms, in whole or in part, without our prior written consent, and any attempted assignment in violation of this Section is void. We may assign or transfer these Terms without restriction, including to an affiliate or in connection with a merger, acquisition, corporate reorganization, or sale of assets.

20.3 Relationship of the Parties

The parties are independent contractors. These Terms do not create any partnership, joint venture, agency, or employment relationship.

20.4 Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable, the remaining provisions will remain in full force and effect, and the invalid provision will be replaced by a valid provision that most closely reflects the parties' original intent.

20.5 No Waiver

A failure or delay by either party to enforce any right or provision of these Terms will not constitute a waiver of that right or provision.

20.6 Venue for Non-Arbitrable Claims and Award Enforcement

To the extent any Dispute is found not to be subject to arbitration (whether because an exception applies or a court of competent jurisdiction so determines), the parties agree that such Dispute will be brought exclusively in the state and federal courts located in San Francisco County, California, U.S.A., and each party irrevocably submits to the personal jurisdiction and venue of such courts for such purposes. Either party may also seek to confirm, enforce, or vacate an arbitration award in those courts.
