Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00129 | $0.02179 |
| Opus 5 | $0.00064 | $0.01090 |
| Sonnet 5 | $0.00026 | $0.00436 |
| Haiku 4.5 | $0.00013 | $0.00218 |
Grade A, and why
apify-product-lookup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apify product lookup
Fetch live product facts instead of guessing at them. Requires the Apify MCP server to be connected; if the tool is missing, see the apify-product-data-setup skill.
Written by a product marketing manager at Apify. It routes to E-commerce Scraping Tool, a paid first-party Apify Actor, so treat the framing accordingly. No affiliate links.
Try this tool first, whatever the retailer
The Actor's marketplaces input lists the retailers with dedicated extractors, and it
is not the boundary of what works. Unlisted sites fall back to generic extraction,
which is enabled by default, so a URL from a shop you have never heard of is still
worth sending.
So the order is always:
- Send the URL or keyword to this tool, regardless of whether the retailer appears in
marketplaces. - If the result is unusable, re-read the URL. An item with every field empty usually means the URL does not resolve, not that the retailer is unsupported.
- Only after that, look for a retailer-specific Actor in Apify Store. See Falling back to Apify Store.
Do not skip step 1 because a domain is missing from the list. That reasoning sends users away from a tool that would have answered them.
When a marketplace is not in the list
Over MCP the marketplaces enum arrives truncated, because the server caps how much
of a long enum it passes through. Some real, supported retailers are therefore missing
from the list you can choose from, and passing one anyway returns a validation error
before the run starts.
That error does not mean the retailer is unsupported. It means you cannot name it in a keyword search on this connection. Two ways through:
- If you have the product URL, use
detailsUrls. It takes arbitrary URLs and is unaffected by the enum, so the retailer works normally. - If you only have a keyword, run it on the marketplaces you can select and say plainly which retailer you could not include. Do not report the retailer as unsupported.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

apify-product-lookup is a skill published in the GitHub repository luispintoapify/ecommerce-agent-starter (3 stars, last pushed 6d ago), licensed MIT. It adds 129 tokens to every session and 2,179 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
