Zinc is now in the AI Services Catalog. Zinc is an API that lets agents search, buy and return products at online stores, and the catalog now lists its four product-data endpoints. With them an agent can search many stores at once, read every seller's offer on a product and pull a product's full details, at $0.01 a call, paid with one Nevermined API key and one budget.

Zinc adds retail data: what real stores sell today, at what price and from which seller. One call searches many stores at once, and three more read one store's results, every seller's offer on a product and a product's full details. We paid a real call through the catalog on 2026-11-11 to check it: a search for 65-inch TVs under $600, cheapest first, came back with six TVs from Walmart, Target, Amazon and Macy's, the cheapest $358 at Walmart.
The listing has four endpoints. Each one takes its inputs as query parameters, with no request body, and Zinc prices every call at $0.01 (listed price, read 2026-11-11).
| Endpoint | What the agent sends | What comes back |
|---|---|---|
POST /agent/search |
q, and optionally a price range, a list of stores, a sort and a limit |
Buyable listings from many stores at once: link, store, title, price, image, rating and availability |
POST /agent/products/search |
query and one retailer |
That store's matches, with product ids, prices, ratings and, where the store has them, identifiers such as the UPC |
POST /agent/products/offers |
product_id and retailer |
Every seller's offer on one product: price, condition, availability and shipping options |
POST /agent/products/details |
product_id and retailer |
The full product: title, brand, images, description, specifications, category, variants and rating |
Coverage differs by endpoint, and Zinc's API reference states it per endpoint (read 2026-11-11). The search across stores covers Amazon, Walmart, Target, Costco, The Home Depot, Lowe's, Wayfair, Chewy, Macy's, Kohl's, Newegg, Staples and B&H Photo, plus Etsy and Shopify stores in Zinc's catalog when the agent names them. The single-store search and the product details cover Amazon in the US, UK, Canada, Germany, France, Mexico and Australia, Walmart, Etsy and Shopify stores in Zinc's catalog. Seller offers cover Amazon and Walmart.
These are the jobs the four endpoints can do today, each one a few calls.
A deal finder that compares stores.
Someone asks their assistant for the cheapest 65-inch TV under $600.
The agent calls /agent/search with q=65 inch tv, max_price=60000 (Zinc takes prices in cents) and sort=price_asc, and gets listings from several stores in one call, each with its price, store and rating.
For the two cheapest matches on Amazon or Walmart it calls /agent/products/offers, because Zinc notes that the price on an Amazon product page is often not the cheapest offer.
Three calls, and the answer names the store, the seller and the condition.
A gift shortlist.
"A gift for a ten-year-old who likes astronomy, under $50."
The agent searches across stores with max_price=5000, then reads /agent/products/details for the three or four closest matches: the description, the feature bullets, the rating and how many reviews it has.
Etsy is in reach when the agent names it (retailer=etsy), and Etsy details say who made the item and whether the shop takes custom requests.
The agent comes back with three options, a line on why each one, and a link to each.
A sourcing agent for parts and supplies. A facilities team needs stainless M6 bolts and a replacement filter for a specific model. The agent runs one search across The Home Depot, Lowe's, Staples, Amazon and Walmart by naming them as stores. For the Amazon and Walmart matches it reads the details, where the specification lines and identifiers such as the model number and the UPC tell an exact match from a lookalike. It hands back the matches, the prices and the stores.
A morning price and stock check.
A brand that sells on its own site wants to know what its products cost on Amazon and Walmart today, and whether they are in stock.
Each morning the agent calls /agent/products/offers for each product, asks for data no older than an hour (max_age=3600), and compares price and availability with the day before.
A list of 50 products is 50 calls, or $0.50 a day at Zinc's price, and the agent only messages someone when something changed.
Filling in product records.
A marketplace or a comparison site holds a list of Amazon ASINs or Walmart item ids with fields missing.
/agent/products/details returns the brand, the category path, the variants and identifiers such as the UPC for each one.
That is enough for an agent to complete the record and match the same product across stores, one call per product.
The agent calls Zinc through the catalog with one Nevermined API key and one budget, and needs no Zinc account and no Zinc key. You set the budget once, as an amount and an expiry. The agent spends against it, it cannot raise it, and you can revoke it in one action. Every call comes out of that budget and is recorded on your ledger, next to everything else the agent bought. What the catalog itself costs is on Nevermined pricing.
From code it is one request to the Nevermined router, naming the service by its catalog slug:
POST https://api.live.nevermined.app/api/v1/router/route
Authorization: Bearer <your Nevermined API key>
Content-Type: application/json
{
"slug": "zinc",
"method": "POST",
"path": "/agent/search",
"search": "q=65+inch+tv&max_price=60000&sort=price_asc",
"delegationId": "<the id of your budget>",
"requestId": "tv-search-1"
}

The reply carries Zinc's JSON and a record of the payment.
The router pays Zinc two ways, x402 with USDC on Base and MPP with USDC on Tempo, and it has paid real calls on both.
It picks one for each call.
If your funds sit on one network, add "requireProtocol": "x402" or "mpp" and it uses only that one.
An agent connected to the catalog over the Catalog MCP can find Zinc and call it the same way, with no code.
Open Zinc in the AI Services Catalog for the copy-paste prompt and the endpoint list, and give your agent its first product search.
