Terms of Service
Last updated 30 August 2026
This document describes how Interva is actually built and what it actually does, but it has not been reviewed by a lawyer. Have counsel review it, and fill in the bracketed placeholders, before relying on it or launching publicly.
1. This agreement
These terms govern your use of Interva — the web application, the REST API, and the MCP server. By using any of them, or by creating an account, you agree to them. If you are agreeing on behalf of an organisation, you confirm you are authorised to bind it.
Provider: [LEGAL ENTITY NAME], [REGISTERED ADDRESS].
2. What Interva is
Interva collects statistical time series published by third-party organisations, maps them onto a common vocabulary of indicators, geographies, and units, and serves the result with provenance attached.
Interva is not the source of this data. We are a harmonization and distribution layer over publications by the World Bank, the World Health Organization, Eurostat, and other statistical agencies.
3. Data licensing and attribution
The underlying data remains subject to its publisher’s licence, and those licences carry obligations that pass to you:
- World Bank — World Development Indicators, generally under Creative Commons Attribution 4.0 (CC BY 4.0). Attribution is required.
- World Health Organization — Global Health Observatory data, under the terms WHO publishes for that dataset.
- Eurostat— under the European Commission’s reuse policy, which requires acknowledgement of the source.
Every series we serve carries a provenance record naming the publisher, the original indicator code, the source URL, and the retrieval date. When you publish, cite, or redistribute anything obtained from Interva, you must attribute the original publisher using that record. Citing Interva alone does not satisfy their licences.
4. Harmonization, and its limits
To make sources comparable, Interva maps publisher-specific codes and names onto canonical ones and groups related indicators under shared concepts. This is interpretive work, and you should understand what it does and does not claim:
- Canonical values are the publisher’s values. We do not restate, smooth, interpolate, or convert currencies.
- Where two publishers measure the same concept differently, we label the pair with a comparability verdict and, where relevant, a structural break. Read these before differencing or charting series together.
- A verdict of not directly comparable means what it says. Combining such series is your decision and your responsibility.
- Mappings are curated and may contain errors. If you find one, tell us.
5. No professional advice
Interva provides data, not advice. Nothing served through it is financial, investment, medical, legal, or policy advice, and it must not be relied on as the sole basis for a decision with financial, clinical, or safety consequences. Verify against the original publisher for any such use.
6. Accounts and API keys
- You are responsible for activity under your account and for keeping API keys secret. Treat a key like a password.
- Tell us promptly at [SECURITY CONTACT EMAIL] if you believe a key has been exposed, and we will revoke it.
- One account per person or organisation. Do not share credentials.
7. Acceptable use
You agree not to:
- exceed published rate limits, or evade them by rotating keys, addresses, or accounts;
- attempt to disrupt, overload, or gain unauthorised access to the service or its infrastructure;
- misrepresent Interva’s data as your own original research, or strip provenance and attribution before redistributing it;
- present harmonized values as a publisher’s official figures without noting the transformation;
- use the service unlawfully, or to infringe anyone’s rights.
Automated and agent access is expressly welcome — that is what the MCP server is for — provided it respects rate limits and attribution.
8. Availability and changes
The service is provided on an as-available basis. We may change, suspend, or discontinue any part of it, including endpoints and canonical codes. For breaking API changes we will give [30]days’ notice to signed-in users where practicable.
Upstream publishers revise, restate, and withdraw their data. Interva reflects those changes, and we do not guarantee that a value retrieved today will match one retrieved later.
9. Disclaimer of warranties
The service and the data are provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty as to the accuracy, completeness, currency, or comparability of any data.
Nothing here excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.
10. Limitation of liability
To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential, or exemplary damages, or for lost profits, revenue, or data, arising from your use of the service. Our aggregate liability is limited to the greater of the amounts you paid us in the twelve months before the claim, or [AMOUNT].
11. Termination
You may stop using Interva and delete your account at any time. We may suspend or terminate access for breach of these terms, or where required by law, and will give notice where we reasonably can.
12. Governing law
These terms are governed by the laws of [JURISDICTION], and the courts of [JURISDICTION] have exclusive jurisdiction, without prejudice to any mandatory consumer rights in your country of residence.
