Pay for decisions, not for guesses
Agents pay per completed decision. You're never charged for errors or for insufficient_evidence, and the price is the same whether the answer is yes or no, so we gain nothing by saying "works".

Agent platforms
Checkout checks for every agent on your platform, volume pricing, a usage dashboard and change webhooks for saved plans.
Retailers and marketplaces
Catalog enrichment (POST /v1/enrich): each SKU's standards and limits as com.tetheredtrust.shopping.compatibility attributes for your feed, so agents can match your products to what customers own.
Manufacturers
Get your products' compatibility confirmed at the source and marked manufacturer_verified in every answer agents receive.
What business plans don't buy
No tier changes a decision. Paying customers, retailers and manufacturers get the same rules and the same answers as everyone else: incompatible stays incompatible, and missing evidence stays insufficient_evidence.
