Terms of Service

Last updated: May 31, 2026

These Terms of Service (“Terms”) govern your use of the Rendex screenshot and rendering API and related services (the “Service”) operated by Copperline Labs LLC (“we,” “our,” or “us”). By using the Service, you agree to these Terms.

1. Definitions

  • “Service” means the Rendex API at api.rendex.dev, the MCP server, documentation, and the rendex.dev website.
  • “API Key” means the unique credential issued to you for authenticating requests to the Service.
  • “Content” means screenshots, rendered images, PDFs, extracted page text (Markdown, JSON, or HTML), and other output generated by the Service on your behalf.
  • “API Call” means a single request to any Service endpoint that produces a billable response.
  • “Plan” means your subscription tier (Free, Starter, Pro, or Enterprise), which determines your monthly API call allowance and rate limits.

2. Account and API Keys

You are responsible for:

  • Maintaining the security and confidentiality of your API keys.
  • All activity that occurs using your API keys, whether authorized by you or not.
  • Providing accurate account information and keeping it current.

You must not share, publish, or embed API keys in client-side code. If you believe your key has been compromised, revoke it immediately via your dashboard. We reserve the right to revoke API keys that are being misused.

3. Service Description

Rendex renders content via a programmatic API: it turns a URL, raw HTML, or Markdown into an image (PNG, JPEG, or WebP) or a PDF, and can extract clean reader-mode text (Markdown, JSON, or HTML) from a page. Capturing a live URL is one mode among several. On a paid plan, the Service can also render pages that require authentication using credentials you supply and are authorized to use (see the Acceptable Use Policy). We strive for high availability but do not guarantee uninterrupted service. The Service depends on third-party infrastructure (Cloudflare, browser engines) that may experience occasional disruptions.

4. Acceptable Use

Your use of the Service is further governed by our Acceptable Use Policy(“AUP”), which is incorporated into these Terms by reference. The AUP defines prohibited uses in detail, including illegal content, unauthorized credential use, fraud, harassment, and infrastructure abuse. A violation of the AUP is a violation of these Terms.

No pre-screening. Except for a narrow Google Safe Browsing check for malware and phishing, Rendex does not pre-screen, filter, classify, or moderate URLs or HTML before rendering. Every other request is rendered as instructed. You are solely responsible for the legality and appropriateness of all content you capture through your account, including content captured by automated systems or AI agents acting under your API key.

You may use the Service for legitimate purposes, including:

  • Generating webpage thumbnails and previews
  • Website monitoring and change detection
  • Content archiving and documentation
  • Automated reporting and content generation
  • AI agent workflows via the MCP server or REST API

You must not use the Service to:

  • Capture pages requiring authentication credentials you do not own or are not authorized to use.
  • Systematically scrape copyrighted content for redistribution or commercial resale without authorization.
  • Generate screenshots for phishing, impersonation, fraud, or any deceptive purpose.
  • Capture, generate, or distribute illegal content of any kind.
  • Circumvent paywalls, access controls, or content protection mechanisms.
  • Conduct load testing, denial-of-service attacks, or any activity intended to degrade the Service.
  • Share, resell, or sublicense your API keys to third parties.
  • Interfere with or disrupt the Service or its underlying infrastructure.

AI agents using the MCP server or API are subject to these same terms. You are responsible for the actions of any automated system operating under your API key.

5. Rate Limits, Plans, and Billing

Each Plan includes a monthly API call allowance and per-minute rate limit. Current pricing and limits are listed at rendex.dev/pricing. Each Plan has a hard monthly cap; requests beyond your Plan’s allowance are rejected until the next billing cycle or until you upgrade. We do not automatically bill overage on top of your Plan. You authorize subscription charges and any Plan changes you initiate.

  • Payments are processed by Stripe. You agree to Stripe’s terms of service for payment processing.
  • Subscriptions renew automatically. You may cancel at any time; access continues until the end of the current billing period.
  • We do not provide refunds for partial billing periods. Plan changes take effect at the next billing cycle.
  • Pricing may change with 30 days’ written notice. Existing subscribers will be notified before changes take effect.

6. Data Processing

Standard synchronous renders are generated on our edge infrastructure, returned directly to you, and not stored. When you use hosted output (hosted: true or /v1/render/link), asynchronous jobs, or batch, the rendered output is stored in our object storage (Cloudflare R2) and served via expiring, signed URLs for the cache lifetime you choose (default 24 hours, minimum 1 hour, maximum 30 days). When a link expires the output is no longer accessible, and the stored object is automatically deleted by our storage lifecycle policy within 30 days of creation. If you configure your own S3-compatible bucket, output is delivered there and governed by your own policies. API request metadata (target URL or hostname, timestamp, response status, latency) is retained for billing accuracy, debugging, and abuse prevention; third-party credentials you pass to render authenticated pages are redacted before storage. See our Privacy Policy for full details.

If you are a business customer who requires a Data Processing Addendum (DPA) under the GDPR, UK GDPR, or similar laws, we will execute our standard DPA on request — contact legal@rendex.dev.

7. Intellectual Property

We own all rights to the Service, API, documentation, and related intellectual property. You retain ownership of Content generated through the Service using your API key. You are solely responsible for ensuring you have the right to capture and use content from target URLs.

8. Third-Party Services

The Service relies on the following third-party providers to operate:

  • Cloud Infrastructure Provider— Edge compute, content delivery, and browser rendering
  • Payment Processor— Payment processing and subscription billing
  • API Key Management Service— Key verification and rate limiting
  • Database Service— Account storage and usage logging
  • URL Threat Intelligence— Malware/phishing screening of target URLs before rendering
  • Geo-Targeting Proxy— Routing renders through a requested country (Pro/Enterprise geo-targeting only)
  • Email Provider— Transactional and account email delivery

Each provider operates under their own terms of service and privacy policies.

9. Disclaimer of Warranties

The Service is provided “as is” and “as available” without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that all websites will render correctly or that screenshots will be pixel-perfect.

10. Limitation of Liability

To the maximum extent permitted by applicable law, Copperline Labs LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, resulting from your use of or inability to use the Service.

In no event shall the total liability of Copperline Labs LLC exceed the greater of: (a) the total amount you have paid to us in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred dollars ($100.00 USD).

11. Indemnification

You agree to indemnify and hold harmless Copperline Labs LLC, its officers, directors, and employees from any claims, damages, losses, or expenses (including reasonable attorney’s fees) arising from your use of the Service, violation of these Terms, or infringement of any third-party rights through Content you generate.

12. Suspension and Termination

We may suspend or terminate your access to the Service at any time for violation of these Terms, non-payment, abuse, or legal obligation. You may cancel your account at any time. Upon termination, your API keys are revoked immediately. Provisions that by their nature should survive termination (including limitation of liability, indemnification, and governing law) will survive.

13. Changes to These Terms

We may update these Terms from time to time. We will notify you of material changes at least 30 days before they take effect via email. Your continued use of the Service after the effective date constitutes acceptance of the revised Terms.

14. Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Wyoming, United States, without regard to its conflict of law provisions. Any disputes arising under these Terms shall be resolved in the courts located in Sheridan County, Wyoming.
