Terms of Service

Last updated: February 20, 2026

Effective Date: February 20, 2026

1. Acceptance of Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and RapierCraft Inc. ("AlterLab," "we," "us," or "our") governing your access to and use of the AlterLab ScraperAPI service, website, and related services (collectively, the "Service").

By accessing or using the Service, creating an account, or clicking "I agree," you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy. If you do not agree to these Terms, you may not access or use the Service.

You represent and warrant that you have the legal capacity to enter into this agreement. If you are entering into these Terms on behalf of a company or organization, you represent that you have the authority to bind that entity to these Terms.

The Service is intended for business and professional use only. By using the Service, you confirm that you are acting in a professional or commercial capacity and not as a consumer. Consumer protection regulations, including cooling-off periods and withdrawal rights under the EU Consumer Rights Directive (Directive 2011/83/EU, Article 16(a)), do not apply to your use of the Service, as it constitutes the supply of digital content that is not supplied on a tangible medium and performance begins upon account creation with your prior express consent.

2. Description of Service

AlterLab provides a web scraping and data extraction API platform that enables developers to programmatically retrieve content from publicly accessible websites. Our Service includes:

  • RESTful API endpoints for web scraping requests
  • JavaScript rendering and dynamic content extraction
  • Proxy rotation and anti-bot detection bypass capabilities
  • Content transformation (PDF extraction, OCR, markdown conversion)
  • Batch processing and webhook notifications
  • API key management and usage analytics
  • Documentation, code examples, and developer tools
  • Bring Your Own Proxy (BYOP) integration for users who wish to connect their own third-party proxy providers

We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time, with or without notice. We will make reasonable efforts to notify you of material changes that affect your use of the Service.

3. Account Registration and Security

3.1 Account Creation

To use the Service, you must create an account by providing accurate, current, and complete information. You agree to:

  • Provide truthful and accurate registration information
  • Maintain and promptly update your account information
  • Use only one account per person or organization
  • Not create accounts through automated means or false pretenses
  • Not share your account with others or allow others to access your account

3.2 Account Security

You are responsible for maintaining the security of your account credentials, including:

  • Keeping your password confidential and secure
  • Safeguarding your API keys and not sharing them publicly
  • Immediately notifying us of any unauthorized access or security breaches
  • Taking responsibility for all activities that occur under your account

We are not liable for any loss or damage arising from your failure to protect your account credentials.

3.3 Age Requirements

You must be at least 18 years old to use the Service. By creating an account, you represent that you meet this age requirement.

4. API Usage Terms

4.1 Concurrency Limits and Fair Use

Your use of the API is subject to concurrency limits based on your account balance. Concurrency refers to the number of simultaneous in-flight requests:

  • $0 balance: 1 concurrent request
  • $1 - $99 balance: 3 concurrent requests
  • $100 - $499 balance: 5 concurrent requests
  • $500 - $999 balance: 10 concurrent requests
  • $1,000 - $1,999 balance: 15 concurrent requests
  • $2,000+ balance: 20 concurrent requests

Unlike traditional rate limits, we do not throttle requests per minute. You can queue unlimited requests—they process based on your concurrency limit. Enterprise customers may request custom concurrency limits.

4.2 Acceptable Use and Prohibited Uses

Your use of the Service is subject to our Acceptable Use Policy, which describes permitted and prohibited uses of the Service in detail. Violation of the Acceptable Use Policy may result in warnings, suspension, or immediate account termination and legal action.

4.3 Compliance Responsibility

You are solely responsible for ensuring that your use of the Service complies with all applicable laws, regulations, and third-party terms of service. This includes, but is not limited to, compliance with the Computer Fraud and Abuse Act (CFAA), Digital Millennium Copyright Act (DMCA), GDPR, CCPA, and website-specific terms of service.

4.4 Data Protection Role

AlterLab acts as neither a Data Controller nor a Data Processor under the General Data Protection Regulation (GDPR) or any other data protection framework with respect to any personal information contained in data you scrape through the Service. The Service functions as a technical tool that retrieves publicly accessible web content at your direction. You are the sole Data Controller for any personal data you collect, process, or store using the Service, and you bear full responsibility for:

  • Establishing and maintaining an appropriate legal basis for processing under GDPR Article 6
  • Conducting Data Protection Impact Assessments (DPIAs) where required
  • Responding to data subject access requests (DSARs) and exercising data subject rights
  • Providing appropriate privacy notices to data subjects whose data you collect
  • Ensuring lawful cross-border data transfers where applicable
  • Reporting data breaches to relevant supervisory authorities where required

You agree to indemnify and hold AlterLab harmless from any claims, fines, or penalties arising from your failure to comply with applicable data protection laws in connection with data you scrape through the Service.

4.5 Bring Your Own Proxy (BYOP)

The Service allows you to connect your own third-party proxy providers ("BYOP") for use with API requests. When you use BYOP, the following terms apply:

  • You are solely responsible for the quality, reliability, availability, and performance of your third-party proxy providers
  • AlterLab makes no warranties, representations, or guarantees regarding the performance, uptime, or output quality of requests routed through your proxies
  • AlterLab is not responsible for any degradation of output quality, scraping failures, timeouts, incomplete results, blocked requests, data inaccuracies, or any other issues arising from the use of your proxy providers
  • You are responsible for maintaining valid credentials, sufficient bandwidth, and adequate capacity with your proxy providers
  • AlterLab does not validate, endorse, or guarantee the security, legality, or compliance of any third-party proxy provider you connect to the Service
  • If your BYOP proxy fails and a request falls back to AlterLab's proxy infrastructure, standard pricing applies to the fallback request
  • You are responsible for ensuring your proxy provider's terms of service permit use through the AlterLab platform

By enabling BYOP, you acknowledge and agree that output quality, success rates, and request performance are dependent on your proxy provider and are outside of AlterLab's control. Any service level expectations, uptime commitments, or performance benchmarks provided by AlterLab apply exclusively to requests routed through AlterLab's own proxy infrastructure and do not extend to BYOP requests.

You agree to indemnify and hold AlterLab harmless from any claims, losses, or damages arising from your use of third-party proxy providers through the Service, including but not limited to claims related to proxy provider outages, data loss, IP reputation issues, or violations of third-party terms of service.

5. Billing and Payment

5.1 Pay-As-You-Go Pricing

AlterLab uses a pay-as-you-go billing model. You deposit funds into your account and pay per request. There are no monthly subscriptions or commitments. Pricing varies by request type:

  • Tier 1 (Curl): $0.0002 per request (5,000 requests per $1)
  • Tier 2 (HTTP): $0.0003 per request (3,333 requests per $1)
  • Tier 3 (Stealth): $0.002 per request (500 requests per $1)
  • Tier 4 (Browser): $0.004 per request (250 requests per $1)
  • Tier 5 (Captcha): $0.02 per request (50 requests per $1)

Current pricing is available at alterlab.io/pricing. We reserve the right to modify pricing with 30 days' notice. Price changes do not affect your existing account balance.

5.2 Account Balance

Funds deposited to your account are stored as a balance. Your balance is deducted in real-time as you make API requests. Your balance never expires and remains available until used. The minimum deposit is $10. New accounts receive a one-time credit of $1 (5,000 light requests) to get started.

5.3 Payment Processing

All payments are processed securely through Stripe, our third-party payment processor. You authorize us to charge your payment method for deposit amounts you initiate. You are responsible for providing accurate and up-to-date payment information.

5.4 Refund Policy

All deposits are final, non-refundable, and non-cancellable. Since your account balance never expires and remains available until used, no refunds are issued under any circumstances. By making a deposit, you acknowledge and agree that you are purchasing prepaid API credits and that all sales are final.

If your account is terminated by us for violation of these Terms, your remaining account balance is forfeited and no refund will be issued. Unused credits are not transferable to another account.

5.5 Chargebacks and Disputes

Filing a chargeback or payment dispute with your bank or credit card provider without first contacting us at [email protected] constitutes a violation of these Terms. If a chargeback is filed against us:

  • Your account will be immediately and permanently suspended
  • Your IP address and associated identifiers will be banned from creating new accounts
  • Any remaining account balance will be forfeited
  • We reserve the right to pursue collection of the disputed amount plus any fees incurred as a result of the chargeback

If you believe a charge is incorrect, you must contact us at [email protected] within 15 days of the transaction to resolve the dispute directly. Failure to contact us within this period constitutes a waiver of any dispute regarding that charge.

5.6 Taxes

All fees are exclusive of applicable taxes (including VAT, sales tax, and similar charges). You are responsible for paying all taxes associated with your use of the Service. If we are required to collect or pay taxes, they will be added to your deposit amount.

5.7 Insufficient Balance

If your account balance reaches zero, API requests will be rejected until you add more funds. Your account and data remain intact—simply deposit funds to resume service. We may send low-balance alerts to help you avoid service interruption.

6. Intellectual Property Rights
