Terms of Use for the OpenLigaDB API

These terms govern access to the API of OpenLigaDB. The rights you have in the retrieved data, on the other hand, are governed by the License (ODbL 1.0) – which remains unaffected by the terms set out here.

What OpenLigaDB is – and what it is not

OpenLigaDB is a privately operated project. It runs on a rented server, financed by the operator. There is no entitlement to availability, accessibility or a particular response time. Maintenance work, outages and changes to the interface are possible at any time without prior notice.

Please plan for this in your application: handle outages gracefully, display cached data, and avoid designs that presuppose permanent availability.

Accuracy of the data

The data is entered and maintained by registered users. There is no editorial review. No warranty is given for accuracy, completeness or timeliness. Delays, gaps and errors occur, especially during live matches. Do not use the data for purposes where an incorrect entry could cause harm.

Fair use

The service is aimed at hobby and specialist applications. To keep it usable for everyone, the following expectations apply to retrieval:

  • Use getlastchangedate as a cheap poll and retrieve the full data only when something has actually changed.
  • During live matches: at most one request every 30 to 60 seconds per league – not per user, not per widget instance and not per club.
  • Outside live matches considerably less often; a few requests per day are usually enough.
  • Stagger your requests in time (jitter) rather than firing exactly on the full minute.
  • Cache results locally instead of repeating identical requests.
  • Respond to status codes 429 and 5xx with exponentially increasing wait times (backoff), not with immediate retries.

If you distribute your application to a larger number of end users, please retrieve the data once, centrally and serve your clients from your own cache, instead of letting every device access the API individually.

Identifying your application

Please set a meaningful User-Agent containing the application name and a way to contact you, for example:

MyApp/1.2 (+https://example.org/myapp; contact@example.org)

This allows the operator to reach you if necessary instead of merely seeing an IP address – and, in case of doubt, to inform you rather than block you. How this information is handled is described in the privacy policy (German).

Measures in case of excessive use

The operator reserves the right to throttle individual requests, clients or IP addresses, and to block them temporarily or permanently, if they impair operation or violate these terms. Where possible and reasonable, a notice will be given beforehand.

Third-party images

Through fields such as TeamIconUrl, the API only provides references to externally hosted images. No rights in them are granted; for details see the License. Please do not permanently embed third-party image URLs without permission, as this burdens third-party servers.

Liability

Use of the API is at your own risk. Liability for damages arising from use, unavailability or incorrect data is excluded to the extent permitted by law. Liability for intent and gross negligence, as well as for damages from injury to life, body or health, remains unaffected.

Changes to these terms

Access to the API is currently free of charge and possible without registration. The operator reserves the right to change these terms and to tie access in the future to registration, API keys or usage quotas in order to finance operation in the long term.

Changes that restrict access will be announced on this page at least four weeks in advance. For projects of the existing scope – in particular non-commercial hobby applications – free access is intended to remain available in the future as well.

The ODbL license in the data, once granted, remains unaffected by such changes and will not be revoked.
