Market Category Booster, one taxonomy level at a time

Field notes

The service models categorization as repeated choices among the children of one marketplace node, rather than asking a model to classify against an entire tree at once. Its example spends 1,233 of a 14,000-token budget across four levels, while the response preserves each store category ID. The homepage also documents an x402 exchange in which a caller learns the price from a 402 response and retries with signed payment metadata.
