API Terms of Use

Access to the API requires a valid MarketSchema account and an API key. Your API key is confidential and tied to your account. You are responsible for all activity conducted using your API key.

You agree to:

• Keep your API key secure and not share it with unauthorized parties
• Immediately revoke and rotate your key if you suspect unauthorized access
• Not embed API keys in client-side code, public repositories, or any publicly accessible location
• Authenticate all API requests using the required X-API-Key header unless a specific endpoint documents a separate stream token

API access is subject to rate limits and usage quotas based on your subscription tier. Current limits are published in the API documentation at marketschema.com/docs and may be updated from time to time.

These limits are illustrative and subject to change. Authoritative rate limits are returned in API response headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset). You are responsible for implementing appropriate rate-limiting logic in your applications.

Exceeding your rate limit will result in HTTP 429 (Too Many Requests) responses. Persistent or deliberate abuse of rate limits may result in temporary or permanent suspension of API access.

You may use the API to:

• Integrate MarketSchema data into your internal applications, dashboards, or analytical tools
• Build applications for personal or internal business use that consume MarketSchema data
• Display MarketSchema data to end users of your application, provided you include the required attribution (see Section 5)

You may NOT:

• Resell, redistribute, sublicense, or provide bulk access to raw API data or responses to third parties
• Use the API to build a product or service that directly competes with MarketSchema
• Scrape, cache, or store API data beyond what is reasonably necessary for your application's functionality (maximum local cache duration: 24 hours unless otherwise specified in your tier)
• Circumvent, disable, or interfere with rate limiting, authentication, or other security features
• Use the API to generate, train, or fine-tune machine learning or artificial intelligence models using MarketSchema data without explicit written permission
• Misrepresent your application's relationship with MarketSchema or imply endorsement
• Use the API for any unlawful purpose or in any manner that could damage, disable, or impair the Service
• Make API calls from automated systems designed to exceed your tier's intended usage through key rotation, distributed requests, or similar techniques

If you display MarketSchema data to end users in any application, website, or publication, you must include the following attribution in a reasonably visible location:

Attribution must link to marketschema.com where hyperlinks are supported. For printed or non-hyperlinked media, the URL must be displayed in text.

You may not modify, reformat, or present MarketSchema index names or values in a way that misrepresents the underlying data or methodology.

API data is provided on an "as is" and "as available" basis. While we strive for accuracy and reliability, we do not guarantee that API data will be error-free, complete, current, or continuously available.

We may modify, deprecate, or discontinue API endpoints, data fields, or response formats at any time. We will make reasonable efforts to provide advance notice of breaking changes through the API documentation and changelog, but are not obligated to do so.

Scheduled maintenance windows may result in temporary API unavailability. We will endeavor to provide advance notice for planned downtime.

These targets are goals, not guarantees. Failure to meet these targets does not entitle you to refunds or credits unless expressly provided in an Enterprise agreement.

The API, its documentation, all index methodologies, proprietary algorithms, and response data structures are the intellectual property of MarketSchema LLC. These API Terms grant you a limited, non-exclusive, non-transferable, revocable license to use the API solely in accordance with these Terms and your subscription tier.

You retain ownership of any applications you build that consume the API, but you acquire no ownership interest in any MarketSchema data, indices, or methodologies.

We reserve the right to suspend or terminate your API access immediately and without notice if we reasonably believe you have violated these API Terms, including but not limited to: exceeding rate limits persistently, unauthorized redistribution of data, security breaches involving your API key, or using the API to build a competing service.

Upon termination, you must immediately cease all use of the API, delete any cached or stored API data (except data already displayed to your end users in non-bulk form), and revoke your API key.

You may terminate your API access at any time by revoking your API key through your account settings.

You agree to indemnify, defend, and hold harmless MarketSchema LLC from any claims, liabilities, damages, or expenses (including reasonable attorneys' fees) arising from your use of the API, your applications built on the API, your violation of these API Terms, or any third-party claims related to your use or display of API data.

We may update these API Terms at any time. Material changes will be communicated through the API documentation, changelog, and/or email notification to registered API users. Continued use of the API after changes constitutes acceptance. If you disagree with changes, your remedy is to stop using the API and revoke your key.

These API Terms are governed by the laws of the State of Idaho, consistent with the MarketSchema Terms of Service. Disputes are subject to binding arbitration as described in the Terms of Service.
