## Data

- Keep data: while in good standing: the licence to use returned results runs "while in good standing"
- Use data: "Free allowances are for evaluation and low-volume use, may require attribution, may change at any time, and permit commercial use only where expressly stated." "You receive a non-exclusive, non-transferable licence to access the APIs and use returned results in your applications while in good standing." "You must not: use the Service unlawfully (including in breach of data protection, consumer, sanctions or export laws), use it to harass, defraud or harm anyone, or to make decisions with legal or similarly significant effects on individuals without human review and a lawful basis, resell or redistribute the Service or substantial portions of its data as a standalone or competing product (integration into a genuinely distinct application is fine), evade limits via key, IP or account rotation, probe or test vulnerabilities without written consent, remove required attributions, or use the Service to build a directly competing lookup dataset." "Where a response indicates an open-license attribution requirement (for example CC BY 4.0 data), you must preserve it in products exposing that data publicly." "API keys are confidential: [...] they may not be shared outside your organisation, published, or embedded in publicly readable client-side code."
