Licensing intermediaries
In short
8 licensing intermediaries are profiled, from marketplaces such as TollBit and Dappier to the RSL standard and IAB Tech Lab's CoMP. 3 of 8 document support for RFC 9309, 1 for Web Bot Auth and 1 for reverse DNS. Most of them price access without blocking anyone, and enforcement stays with the publisher's CDN or bot manager.
The 8 licensing intermediaries run alphabetically from Dappier to TollBit, and carry 85 sourced facts between them.
The price models on record include publisher-set price per query; open specification; sales-led; annual subscription; free with Tools Portal registration; and 5 more. None of the profiles carries a key directory or IP file probe of our own. Each profile lists what the vendor does not do next to what it does.
