When is this useful?
A bounded research selection with recorded filters and entity IDs.
Access & pricing
No key
Basic queries can omit a key. Your own email-activated key raises the budget and is required for subsequent cursor pages.
Free tier + paid
Basic keyless use is free; a free account key provides a daily budget. Additional usage and annual plans are paid.
Pricing at the source ↗Get your own key only from the provider. Never enter keys or tokens here.
Limitations & terms
Free use has a budget; your own key raises it and heavier use can cost money. The CC0 catalog license does not automatically cover linked full texts.
Commercial use: Allowed per source
No terms source recorded; permission has not been established.
