4. Account Registration

To access certain features of the Service, you must register for an account. When registering, you agree to:

  • Provide accurate, current, and complete information during the registration process
  • Maintain and promptly update your account information to keep it accurate, current, and complete
  • Maintain the security and confidentiality of your account credentials, including your password and any API keys

We reserve the right to suspend or terminate accounts that contain inaccurate information or that we reasonably believe have been compromised.

5. Subscription Plans & Billing

The Service is offered under the following subscription tiers:

  • 7-Day Trial: New users receive a 7-day trial with 200 Credits and access to all Cloud API Platform services. A valid credit card is required at signup. After 7 days, your trial automatically converts to a Pro subscription at $19.99/month and your card will be charged unless you cancel before the trial ends. You will receive reminder emails at day 5 and day 7 before any charge occurs.
  • Pro ($19.99/month): Includes 2,000 Credits per month, full Guardian security, curated skill packs, over-the-air rule updates, all Cloud API Platform services, and priority support.
  • Max ($49/month): Includes 5,000 Credits per month, higher rate limits, increased concurrent request limits, and all Pro features.
  • Enterprise: Custom pricing with dedicated support, custom rate limits, team management, SSO, private cloud routing, and a custom service-level agreement. Contact hello@hexaclaw.com for details.

Credit Packs

You may purchase additional Credit packs at any time in denominations ranging from $10 to $100. Purchased Credits are non-refundable, do not expire while your account remains active, and are not transferable between accounts. Credits cannot be converted to cash or applied toward subscription fees. Monthly allotment Credits that are unused at the end of a billing cycle do not roll over. For dormant accounts (no login or API activity for 12 consecutive months), purchased Credits expire. We will send a warning email 30 days before expiration. Any login or API request resets the dormancy clock.

Billing

Subscriptions are billed on a recurring monthly basis through Stripe. By subscribing, you authorize us to charge your payment method on each billing cycle until you cancel.

We reserve the right to change subscription prices with at least thirty (30) days' prior written notice. Price changes will take effect at the start of your next billing cycle following the notice period.

All applicable taxes, duties, and levies are your responsibility unless otherwise stated. For information about cancellations and refunds, please see our Refund Policy.

7. Product Delivery & Updates

The Service is delivered digitally. After registration or purchase, you will receive access to download the applicable software, configuration files, skill packs, Guardian rules, and documentation as described for your subscription tier.

Trial: Includes the version of the Service available at the time of installation during your 7-day trial period. Future updates are included as released at our discretion.

Pro tier: Includes priority security updates, new Guardian rules, updated curated skill packs, and new features for the duration of your active subscription. Upon cancellation or expiration of your subscription, you retain the version installed at that time but will no longer receive Pro-tier updates.

8. Guardian Security Service

Guardian is a core component of the Service that provides runtime security monitoring for AI agent activity. The following subsections describe the nature, scope, and limitations of Guardian.

8.1 Nature of Service

Guardian uses a multi-tiered approach to threat detection, including pattern matching (regular expressions), heuristic behavioral analysis, and machine-learning classification. It operates by intercepting and analyzing tool calls, agent outputs, and skill activity in real time. Guardian is designed to function as one layer in a defense-in-depth security strategy.

8.2 No Guarantee of Detection

Guardian cannot and does not guarantee the detection of all security threats. New attack techniques, zero-day exploits, novel social engineering methods, and previously unseen malicious patterns may bypass Guardian's detection capabilities. We make commercially reasonable efforts to update detection rules and improve Guardian's capabilities on an ongoing basis, but there will always be a gap between threat emergence and rule availability.

8.3 Not a Substitute for Comprehensive Security

Guardian is not a substitute for comprehensive security practices. You should maintain and employ additional security measures including, but not limited to:

  • Regular security audits of your systems and workflows
  • Access control policies and least-privilege principles
  • Network security measures (firewalls, intrusion detection)
  • Employee security awareness training
  • Incident response plans and disaster recovery procedures
  • Regular backup and data protection practices

8.4 Evolving Threat Landscape

The security threat landscape for AI agents and skills changes rapidly. New attack vectors, prompt injection techniques, and malicious skill behaviors emerge on a regular basis. There may be delays between the emergence of new threats and the availability of corresponding Guardian rules or updates. We do not guarantee any specific response time for new threat coverage.

8.5 Third-Party Dependencies

Guardian's effectiveness depends on factors outside our control, including but not limited to the security of your underlying operating system, the behavior of third-party skills and extensions, the behavior and output of AI models, network conditions, and system resource availability. We are not responsible for security failures attributable to these external factors.

8.6 User Responsibility

You remain solely responsible for the security of your systems, data, credentials, and computing environment. You should not rely exclusively on Guardian for security. You are responsible for reviewing skill permissions, monitoring agent activity, and maintaining appropriate security hygiene for your environment.

8.7 Commercially Reasonable Efforts

We commit to commercially reasonable efforts to maintain and update Guardian detection rules, respond to reported vulnerabilities in a timely manner, improve detection capabilities through ongoing research and development, and communicate significant security findings to affected users. "Commercially reasonable" means efforts consistent with accepted practices in the security software industry, taking into account the size and resources of our organization.

9. Curated Skill Packs

Curated skill packs are collections of skills that have been selected based on our security review criteria. These packs are available to Pro subscribers and may include productivity, developer, content, and other categorized skill bundles.

While we apply security review criteria to skills included in curated packs, we do not guarantee that curated skills are free from all vulnerabilities, bugs, or security issues. Skills may be added to, removed from, or updated within curated packs at our discretion based on ongoing security assessments.

You should review the permissions and capabilities of any skill before enabling it, even within curated packs. You are responsible for evaluating whether a skill is appropriate for your use case and security requirements.

10. Cloud API Platform

The Cloud API Platform is a unified proxy that routes your API requests to Third-Party Providers through a single API Key and credit-based billing system. Usage is metered per request based on the specific service, model, and token volume consumed.

10.1 Available Services

The Cloud API Platform currently provides access to:

  • LLM Completions: Text generation via models from Anthropic (Claude), OpenAI (GPT, o-series), Google (Gemini), DeepSeek, Mistral, Groq, and xAI (Grok)
  • Embeddings: Vector embeddings for semantic search and retrieval via OpenAI and Google models
  • Web Search: Real-time web search results via the Brave Search API
  • Image Generation: AI-generated images via fal.ai (Flux models) at multiple quality tiers
  • Text-to-Speech (TTS): Audio synthesis from text via OpenAI TTS models
  • Speech-to-Text (STT): Audio transcription via OpenAI Whisper
  • Browser Automation: Cloud browser sessions for web interaction via Browserbase
  • Vector Storage: Persistent semantic memory with vector storage and retrieval
  • Guardian Scanning: AI safety and content threat analysis

We may add, modify, or discontinue individual services within the Cloud API Platform with reasonable notice. Changes that materially reduce the functionality of your current subscription tier will be communicated at least thirty (30) days in advance.

10.2 Third-Party Provider Terms

The Cloud API Platform routes your requests to Third-Party Providers. While HexaClaw manages authentication, billing, and request routing, the underlying AI models and services are operated by their respective providers. You acknowledge that:

  • Third-Party Provider acceptable use policies apply to the content you submit through the Cloud API Platform, and you are responsible for compliance
  • AI model outputs are generated by Third-Party Providers and may contain inaccuracies, biases, hallucinations, or errors
  • HexaClaw does not control, endorse, or guarantee the accuracy, completeness, or reliability of any AI-generated output
  • Third-Party Providers may update, modify, or deprecate their models at any time, which may affect the output quality or availability of specific models
  • You are solely responsible for evaluating and validating AI outputs before relying on them for any decision or action

10.3 Rate Limits & Fair Use

Each subscription tier includes rate limits to ensure fair access for all users. Current rate limits are published on our pricing page and may be adjusted with notice. Attempts to circumvent rate limits through multiple accounts, request manipulation, or other technical means constitute a violation of these Terms.

10.4 BYOK (Bring Your Own Key)

The BYOK feature allows you to use your own Third-Party Provider API keys with HexaClaw's routing and management infrastructure for a reduced platform fee. When using BYOK:

  • You are directly bound by the terms of service of the applicable Third-Party Provider for your API key
  • You are responsible for the security of your own API keys and any charges incurred on your Third-Party Provider accounts
  • HexaClaw charges a platform fee of 5% of the equivalent Credit cost (minimum 1 Credit per request) for routing, monitoring, and management services
  • HexaClaw is not liable for any charges, data processing, or service disruptions related to your own Third-Party Provider accounts

10.5 AI Output Disclaimer

AI-generated outputs accessed through the Cloud API Platform (including text completions, images, audio, embeddings, and search results) are provided for informational purposes only. HexaClaw does not warrant that AI outputs are accurate, complete, current, or suitable for any particular purpose. You must not rely on AI outputs as a substitute for professional advice (legal, medical, financial, or otherwise). You are solely responsible for any actions taken based on AI-generated content.

10.6 Content Ownership

You retain ownership of all input content you submit through the Cloud API Platform. Ownership of AI-generated outputs is governed by the applicable Third-Party Provider's terms and applicable intellectual property law. HexaClaw claims no ownership over your inputs or the outputs generated from them.

11. Acceptable Use

Your use of the Service is subject to our Acceptable Use Policy, which is incorporated into these Terms by reference.

You agree not to misuse the Service, including but not limited to using it for illegal purposes, attempting to circumvent security measures on systems you do not own or have authorization to test, or interfering with the operation of the Service for other users.

Violations of the Acceptable Use Policy may result in suspension or termination of your account and access to the Service, at our sole discretion.

12. Intellectual Property

The Service, including the Guardian engine, HexaClaw branding, website design, documentation, curated skill pack selections, and all proprietary code, is owned by HexaClaw and protected by intellectual property laws. All rights not expressly granted in these Terms are reserved.

You retain full ownership of your data, configurations, custom skills, and any content you create or process using the Service. We claim no ownership rights over your data.

Certain components of the Service incorporate open-source software licensed under the MIT License. These components are governed by their respective licenses as described in Section 20 of these Terms.
