Terms of Service

These terms govern your use of Interva — the web application at interva.co, the REST API, and the MCP server. By using any of them, creating an account, or buying a plan, you agree to them. If you are agreeing on behalf of an organisation, you confirm you are authorised to bind it.

Interva is provided by Electric Sheep Africa Ltd(“Electric Sheep”, “we”, “us”), a company registered in Nigeria.

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. It includes a free catalog and, on a paid plan, the Desk (country briefs and Ask, a chat that answers questions from the catalog) and Compare (series from different publishers side by side).

Interva is not the source of this data. We are a harmonization and distribution layer over publications by the World Bank, the International Monetary Fund, the World Health Organization, Eurostat and other statistical agencies.

The underlying data remains subject to its publisher’s licence, and those licences carry obligations that pass to you:

• World Bank — World Development Indicators and International Debt Statistics, under Creative Commons Attribution 4.0 (CC BY 4.0). Attribution is required.
• International Monetary Fund— under the IMF’s copyright and usage terms, which require the IMF to be cited as the source.
• World Health Organization — Global Health Observatory data, under Creative Commons Attribution-NonCommercial-ShareAlike 3.0 IGO. That licence restricts commercial reuse; if your use is commercial, it is your responsibility to obtain any permission WHO requires.
• Eurostat— under the European Commission’s reuse policy (CC BY 4.0), which requires acknowledgement of the source.

Every series we serve carries a provenance recordnaming 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. A paid plan pays for Interva’s service, not for a licence to the data itself.

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:

• Values are the publisher’s values. We do not restate, smooth, interpolate or convert currencies.
• Where a publisher marks figures as projections or forecasts, Interva shows them as such, separately from observations.
• 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.
• Mappings are curated and may contain errors. If you find one, tell us.

Ask answers questions in plain language using a third-party large language model, currently Mistral Large 4 served through NVIDIA. The model chooses which catalog lookups to make and writes the answer. You should know:

• Answers can be wrong, incomplete or misleading, even when they read confidently.
• Every figure in an answer is checked against what the catalog returned for that question. Figures that do not match — including arithmetic the model did itself — are marked, and each cited dataset links to its source. Check the marks and the sources before relying on an answer.
• Your questions, and the catalog data needed to answer them, are sent to the model provider for processing. Do not include personal, confidential or sensitive information in a question.
• We may change the model or provider at any time.

Interva provides data and assistance, not advice. Nothing served through it, including an answer from Ask, is financial, investment, medical, legal or policy advice, and it must not be the sole basis for a decision with financial, clinical or safety consequences. Verify against the original publisher for any such use.

• Plans. Pro (US$9 a month, 100 questions a month in Ask), Pro Heavy (US$29 a month, 500 questions) and Team (US$35 per seat a month, at least two seats, 500 questions per seat). Current prices and what each plan includes are on the pricing page. The catalog, series pages, registry and provenance are free.
• Payment. Plans are billed monthly in advance, in US dollars, through our payment processor, Stripe. Prices exclude any taxes that apply to you. A plan renews automatically each month until you cancel.
• Cancelling. You can cancel at any time from Manage billing on your Dashboard. Your plan stays active until the end of the period you have paid for, and then ends. Payments are not refunded for partial periods, except where the law requires it.
• Questions.A plan’s questions reset at the start of each calendar month (UTC) and do not roll over. A question counts when it is answered; one that fails is not counted.
• Failed payments. If a payment fails, the plan stays active while Stripe retries the card; if it still fails, the account returns to the free plan.
• Price changes.We will give at least 30 days’ notice by email before a price change applies to an existing subscription.
• Team.The person who buys a Team plan is its owner and is responsible for its seats, its members and its bill. Each seat is for one person. Seats added or removed during a period are prorated. Members have access only while the owner’s subscription is active and they hold a seat.

• You sign in with a one-time code sent to your email. You are responsible for activity under your account and for keeping your email account and any API keys secure.
• Tell us promptly at kossi@electricsheep.africa if you believe your account or a key has been compromised, and we will act on it.
• One account per person. Do not share an account or a seat.

You agree not to:

• exceed rate limits or question allowances, or evade them by rotating keys, addresses or accounts;
• attempt to disrupt, overload or gain unauthorised access to the service or its infrastructure, or to the model behind Ask;
• 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 welcome — that is what the API and the MCP server are for — provided it respects rate limits and attribution.

The service is provided on an as-availablebasis. 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. We may change these terms; if a change is material we will tell signed-in users before it takes effect, and continuing to use Interva after that means you accept it.

The service, the data and answers from Ask 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 or answer.

Nothing here excludes liability that cannot lawfully be excluded, including for death or personal injury caused by negligence, or for fraud.

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 US$100.

You may stop using Interva at any time, and ask us to delete your account and its data (including saved chats and bookmarks) by writing to kossi@electricsheep.africa. Cancel any paid plan first. We may suspend or terminate access for breach of these terms, for non-payment, or where required by law, and will give notice where we reasonably can.

These terms are governed by the laws of the Federal Republic of Nigeria, and the courts of Lagos State, Nigeria, have exclusive jurisdiction, without prejudice to any mandatory consumer rights in your country of residence.
