Legal API Terms of Service

Empirical Markets API — Terms of Service

These Terms govern access to and use of the Empirical Markets API (the “API”). By using the API, you agree to these Terms.

On this page

1. Eligibility

You must be at least the age of majority in your place of residence (and in any event 18+) and capable of forming a binding contract to use the API.

If you access or use the API on behalf of a company or other legal entity, you represent and warrant that you have the authority to bind that entity to these Terms and that the entity accepts these Terms.

You may not use the API if you are barred from receiving services under applicable laws (including export control and sanctions laws) or if your use would cause us to violate such laws.

2. License and Access

License Grant. Subject to these Terms, Empirical Markets (the “Company,” “we,” “us,” or “our”) grants you a limited, non-exclusive, non-transferable, revocable license to access and use the API solely for your internal business or personal purposes.

Restrictions. You may not: (a) copy, modify, distribute, sublicense, resell, or otherwise exploit the API or its outputs except as expressly permitted; (b) circumvent, disable, or interfere with authentication, rate limits, or access controls; (c) use the API in violation of applicable laws or regulations; or (d) use the API in a way intended to replicate or substitute the API.

3. Data Sources

  • Public Data. Many endpoints deliver data derived from publicly available sources (e.g., SEC, Treasury.gov). While we strive for accuracy and timeliness, we do not guarantee completeness, accuracy, or up-to-date status.
  • Data Transformations, Indicators, & AI Predictions. The API provides proprietary transformations, indicators, and AI model predictions. These outputs are for your use only and may not be redistributed, republished, or resold without our prior written consent.
  • Licensed Data. In the future, certain datasets licensed from others may be included. Such data is subject to additional third‑party restrictions that are incorporated by reference; where conflicts exist, the most restrictive terms apply.

4. Rate Limits & Usage

  • Tiers. API usage is subject to subscription tiers, which currently provide full endpoint access with differing rate limits.
  • Rolling Window. Usage is measured on a rolling 30‑day basis per account and per API key.
  • Exceeding Limits. If you exceed your tier’s limits, we will suspend your access until the 30-day cumulative usage falls back beneath the rolling 30-day rate limit.
  • Global Rate Limits. In addition to your subscription tier's limit, we enforce a global rate limit of 3 requests per second. Exceeding this limit may result in the temporary suspension of your API access. Continually exceeding this limit will result in the permanent suspension of your access. In this case, your current subscription will be automatically canceled.
  • Fair Use. You agree not to burden or disrupt the service (e.g., abusive call patterns or scraping). We may take reasonable steps to protect the service and other users.

5. Ownership

Company IP. All rights, title, and interest in and to the API, including software, documentation, models, transformations, and predictions, are owned by Empirical Markets and its licensors.

Your Apps. You retain rights to your applications and services that integrate with the API, subject to our rights in the API and its outputs.

6. Prohibited Uses

  1. Use the API to violate laws, regulations, or the rights of others.
  2. Redistribute or resell proprietary transformations, indicators, or AI predictions, or create a competing dataset primarily derived from those outputs.
  3. Misrepresent API outputs as your own original research without appropriate attribution.
  4. Engage in automated high‑volume queries designed to replicate or substitute the service.

7. Disclaimer of Warranties

THE API IS PROVIDED “AS IS” AND “AS AVAILABLE.” WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON‑INFRINGEMENT. DATA MAY CONTAIN ERRORS, OMISSIONS, OR DELAYS. PAST PERFORMANCE DOES NOT GUARANTEE FUTURE RESULTS.

8. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, EMPIRICAL MARKETS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING FROM OR RELATING TO YOUR USE OF THE API OR RELIANCE ON ITS OUTPUTS. OUR TOTAL LIABILITY UNDER THESE TERMS SHALL NOT EXCEED THE GREATER OF (i) THE FEES YOU PAID FOR API ACCESS IN THE SIX (6) MONTHS PRECEDING THE CLAIM, OR (ii) $100.

9. Termination

We may suspend or terminate your access to the API at any time, with or without cause or notice, including for violations of these Terms. Upon termination, your license to use the API immediately ends, and you must cease use and delete any cached or stored proprietary outputs (including transformations and AI predictions), except where retention is required by law.

10. Changes

We may modify these Terms at any time. The “Last Updated” date above indicates the effective date of the most recent changes. Your continued use of the API after changes become effective constitutes acceptance of the updated Terms.

11. Governing Law

These Terms are governed by the laws of the State of Delaware, without regard to conflict of law principles. Venue and jurisdiction shall lie exclusively in the state or federal courts located in Delaware, USA.
