What it does

Apify Product Lookup is an agent skill from davepoon/buildwithclaude. Fetch a real product's current price, stock, rating, or images from retailer pages over the Apify MCP server, and return them as typed fields rather than prose. Use when someone asks what a product costs right now, whether it is in stock, how it is rated, to compare a product across retailers, or to check a product URL they pasted. Also use when an agent would otherwise answer a product question from training data. Not for managing your own store's catalog, not for payments, and not for questions answerable…

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Web scraping. It works with Apify and Model Context Protocol. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.

When your agent uses it

  • Someone asks what a product costs right now
  • Whether it is in stock
  • How it is rated
  • Compare a product across retailers

Example prompts

  • “/apify-product-lookup”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Call apify--e-commerce-scraping-tool (two hyphens, not a slash). It returns run
  2. Check status. If it is not SUCCEEDED, call get-actor-run with the runId and
  3. Call get-dataset-items with the datasetId, a limit, and fields.

What it can do on your machine

Read from SKILL.md and the folder at commit 616deb5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • mcp.apify.com

    Also links to:

    • apify.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Apify Product Lookup loads about 1.4k tokens when it runs. Until then it costs about 140 tokens; SKILL.md has 793 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~140
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Apify product lookup

A model answers product questions from training data that was fixed months ago, or by reading a page as prose with no product fields. This skill routes the question to a hosted Actor that reads retailer pages on request and returns structured records: price, currency, stock, rating, image URLs, and a link.

Written by a product marketing manager at Apify. It calls E-commerce Scraping Tool, a paid first-party Apify Actor, so weigh the framing accordingly. Everything below is what testing against the live Actor returned, including where it does not work.

Setup

The MCP endpoint is https://mcp.apify.com. Appending ?tools=apify/e-commerce-scraping-tool narrows the server to this one Actor, which makes tool selection more reliable when product data is the only job. Authentication is OAuth on first use for interactive clients, or a bearer token for unattended ones. An Apify account is required and the Actor is paid, billed per run started plus per product returned.

Pick the input before calling

The questionInput to send
About a specific page the user gave youdetailsUrls: [{"url": "..."}]
"Find me an X under $Y" with no URLkeyword plus marketplaces
"Compare X across stores"keyword plus several marketplaces

Always send maxProductResults and additionalProperties: true. Without the second, stock, rating, list price and identifiers are all missing, because they are nested there rather than at the top level.

The call is two steps, sometimes three

  1. Call apify--e-commerce-scraping-tool (two hyphens, not a slash). It returns run metadata and a datasetId. It does not return products.
  2. Check status. If it is not SUCCEEDED, call get-actor-run with the runId and a waitSecs until it is. The Actor tool returns when its own wait window elapses, not when the run finishes, so RUNNING is a normal answer and the dataset holds nothing at that moment.
  3. Call get-dataset-items with the datasetId, a limit, and fields.

Two failures live here. Stopping after step 1 returns a result that reads like success and holds no product data. Skipping step 2 fetches an empty dataset and reports the product as not found, intermittently, depending only on how fast the retailer answered.

Project with fields, and read them defensively

The full record is large: one Amazon product measured about 88 KB across 142 fields, most of it marketing content and review text. Pass fields in dot notation, naming only what the question needs.

Projected output comes back flat. The dots stay in the key names, so it is item["offers.price"], not item["offers"]["price"]. Walking the nested path against a projected response finds nothing, which is indistinguishable from the retailer not reporting the field.

The four differences that bite hardest:

  • offers.price is a number on some retailers and a string on others.
  • Currency is offers.priceCurrency on some and offers.currency on others, and the value may be a symbol or an ISO code.
  • Stock and rating live under additionalProperties, as inStock and stars, not at the top level. Top-level rating was null on a product whose stars was 4.2.
  • brand frequently carries marketing text such as Visit the Sony Store rather than a brand name.

Answer honestly

  • Say when the data was read. The point of the call is that the answer is current, so make that visible.
  • Never claim a product is unavailable because stock was absent. Many retailers do not report it. Absent means unknown.
  • If every field comes back empty, suspect the URL before the retailer. An unresolvable URL returns an item with no fields rather than an error.
  • Quote the source URL so the user can check it.

Scope and limits

  • Latency is high and unstable. Measured end to end over MCP across twenty questions: 14.7s fastest, 24.1s median, 95.8s slowest. Treat a runtime call as verification before the user acts, not as something to put inside every turn.
  • The marketplaces enum arrives truncated over MCP, because the server caps how many characters of a long enum it forwards. Measured on 2026-08-27: of 249 values, 122 fit and 127 were dropped. A validation error naming marketplaces means the retailer cannot be named in a keyword search on this connection, not that it is unsupported. Use detailsUrls, which takes arbitrary URLs and is unaffected.
  • Field coverage is a property of the retailer, not the tool. On one measured run, Amazon returned 44 keys under additionalProperties and two other retailers returned 4, with stock and rating absent on every record from one of them. There is no unified schema to rely on.
  • Cost. Cap with maxProductResults. Prefer one call with several URLs or marketplaces over several calls, and never re-run to check a result you already have.
  • additionalProperties can reach roughly 100 KB for one product. Never paste it into a reply.
  • A rating or stars of 0 means absent, not a zero-star product.
