Assetli Data API — Terms of Use

Last updated: 3 July 2026 Version: 1.0

1. Introductory provisions

1.1 Provider

The Assetli Data API (the "API") is provided by:

Ondřej Smutný Company ID (IČO): 75343533 Registered office: Družstevní 511, 294 41 Dobrovice, Czech Republic E-mail: info@assetli.app Web: https://assetli.app Not a VAT payer

(the "Provider")

1.2 Scope

These terms govern access to the API and the use of data obtained from it (the "Data") by a customer to whom the Provider has issued an API key (the "Customer"). By using an API key, the Customer agrees to these terms. Use of the Assetli application itself is governed by the separate Terms of Service.

1.3 Nature of the Data

The API provides market data only — normalised energy supplier price lists and official interest-rate statistics, obtained from public official sources (regulators, central banks, suppliers' official price lists). The API never contains personal data or data of Assetli application users.

2. Licence

2.1 Licence grant

The Provider grants the Customer a non-exclusive, non-transferable, non-sublicensable and revocable licence to use the Data for the duration of the subscription, within the scope of Section 3 (permitted uses). The licence covers one organisation; the API key is intended solely for that organisation's internal systems and products.

2.2 Database rights

The database made available through the API is protected by the sui generis database right (Sec. 88 et seq. of Czech Act No. 121/2000 Coll.; Directive 96/9/EC). Individual facts (individual prices, rates) remain public facts; the subject of protection and of this licence is the database as a whole, its substantial parts and its normalisation. Third-party rights (of the data sources) remain unaffected.

3. Permitted uses

The Customer may, always subject to the attribution obligation in Section 4:

  1. display the Data to end users in its own applications, websites, widgets and dashboards, including commercial ones,
  2. perform internal analyses and create internal reports,
  3. publish citations, charts and tables created from the Data (journalism, research, content) — but not a machine-readable copy of a substantial part of the database,
  4. create and publish derived works (aggregates, indexes, analytical conclusions) that do not substitute the database itself,
  5. cache the Data for up to 7 days for the performance of the Customer's own application.

4. Attribution (mandatory)

  1. Every API response contains an attribution field. The Customer must visibly display this attribution wherever the Data or outputs derived from it are displayed or published.
  2. Attribution requirements of the original sources (e.g. CRE — Licence Ouverte, Ofgem/Bank of England — Open Government Licence, ECB, Deutsche Bundesbank, Czech National Bank, Czech Banking Association, Bundesnetzagentur) pass through to the Customer, who must comply with them.
  3. Removing, hiding or altering the attribution is a material breach of these terms.

5. Prohibited uses

The Customer must not:

  1. resell, redistribute or publish the raw Data or a substantial part of the database — in any form (own API, bulk files, data exports for third parties),
  2. provide API access to third parties — share, lend or sell the API key; the key is bound to the Customer's organisation,
  3. build a competing data product from the Data (a database, API or data feed offered to third parties),
  4. systematically extract the Data in order to reconstruct the database (repeated bulk downloading beyond normal use),
  5. train machine-learning models whose purpose is to reproduce or substitute the database (analytical and research use of the Data by a model is not affected),
  6. remove attribution or present the Data as the Customer's own database,
  7. circumvent request limits, security measures or payment obligations (including repeated use of the trial period),
  8. use the Data in violation of applicable law.

Redistribution of the raw database or a substantial part of it requires a separate written licence — contact info@assetli.app.

6. Trial, price and payments

  1. The current price, plan contents and request limits are published at assetli.app/data-api (the "Price List"). Changes to the Price List are announced by e-mail at least 30 days in advance and have no retroactive effect.
  2. The trial is free of charge, for the period stated in the Price List, one per organisation. After it expires, access ends automatically unless a subscription is ordered.
  3. The subscription is monthly; in case of non-payment the Provider may deactivate access.

7. Data quality and disclaimer

  1. The Data is provided "as is". The Provider applies professional care (validation gates, self-checks, provenance on every record) but does not warrant the completeness, accuracy or continuous currency of the Data; source institutions may revise values retrospectively.
  2. The Data does not constitute financial, investment or legal advice. The Customer bears responsibility for its use of the Data and for decisions based on it.
  3. The standard plan does not include an SLA; the API is provided with due care but without an availability guarantee.

8. API operation

  1. Request limits per the Price List apply; exceeding them returns HTTP 429.
  2. The Provider logs API usage (without the content of the Customer's data) for operations, billing and compliance purposes.
  3. The Provider may develop the API further; backwards-incompatible changes will be announced by e-mail at least 30 days in advance. In case of a material breach, the Provider may suspend access immediately.

9. Term and termination

  1. Either party may terminate the subscription as of the end of the paid period.
  2. Upon termination, the licence under Section 2 expires. Within 30 days the Customer shall delete stored copies of the raw Data; outputs already published in compliance with these terms (charts, articles, derived works with attribution) may remain published.
  3. Sections 4, 5, 7, 10 and 11 survive termination.

10. Liability

The Provider's total liability for damage arising in connection with the API is limited to the amount paid by the Customer in the preceding 12 months. The Provider is not liable for lost profit or indirect damage. Liability that cannot be limited under applicable law remains unaffected.

11. Final provisions

  1. These terms are governed by the laws of the Czech Republic; the courts of the Czech Republic have jurisdiction.
  2. The Provider may amend these terms with at least 14 days' notice by e-mail. Continued use of the API constitutes acceptance; otherwise the Customer may terminate the subscription.
  3. These terms are executed in Czech and English; in case of conflict, the Czech version prevails.
