What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of mcb.r6i.it controls every word below.

Categorize a product into a marketplace taxonomy

Maps a free-text product description onto the live category taxonomy of a marketplace (Amazon, eBay, Shopify, Google) and returns the full path: one match per taxonomy level, from the broadest category down to the most specific one, each with the reason it was picked. Use it to assign a listing category to a product you only have prose for. The last match carries truncated=true when the per-request token budget stopped the descent, so the path is valid but not necessarily a leaf. Billed per call: needs an API key or an x402 payment.

Examples it gives

{"method": "SendMessage", "params": {"message": {"role": "ROLE_USER", "parts": [{"data": {"skill": "categorize-product", "description": "over-ear bluetooth headphones with active noise cancelling", "store_id": "amazon.it"}}]}}}

List supported marketplaces

Returns the marketplaces whose taxonomy is loaded, i.e. the accepted values of store_id. Free of charge: without it an agent would have to pay for a failed call to discover them.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: r6i — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 0.1.3
Auth schemes: apiKey
Extensions: https://market-category-booster.com/a2a/extensions/skill-schemas/v1
JSON Schema of the input and output of each skill, keyed by skill id, each as a JSON-encoded string. A2A 1.0 has no field for this on AgentSkill.

Pay per call with x402 instead of holding an API key. A request with neither credential gets HTTP 402 — at the HTTP level, not as a task in TASK_STATE_AUTH_REQUIRED — with the payment requirements in the body and in the PAYMENT-REQUIRED header; retry w

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: complete all eight fields required by a2a.proto v1.0
