Barcode Lookup
Add Barcode Lookup to your product for your customers, and give your AI agents governed access to it.
Barcode Lookup exposes a single read-only REST resource, GET /v3/products on api.barcodelookup.com, and the key travels as a `key` query parameter rather than an Authorization header, so it leaks into logs unless you strip it. You can query by `barcode`, `mpn`, `asin`, `title` or a free-text `search` term, and the response returns a `products` array where each entry carries barcode_formats, brand, manufacturer, category, an images list and a `stores` array of retailer prices with currency codes. The catalogue is crowd-supplemented, so field coverage is uneven: a barcode may resolve with a title and nothing else, and unrecognised barcodes come back as an HTTP 404 rather than an empty array, which breaks naive parsers. Plans are metered by daily and monthly call caps, so a bulk enrichment job needs its own throttling and a local cache of resolved barcodes. There are no writes and no webhooks, which makes freshness entirely your responsibility. fastn stores each customer's key, applies the per-plan rate limits and keeps the calls working as the vendor rotates credentials.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own Barcode Lookup account so scanned barcodes in your app resolve to product names and images under their own quota
Enrich a retailer's catalogue rows that only have a UPC with brand, category and manufacturer fields
Show competing store prices next to a customer's own listing by reading the stores array for a matched barcode
Validate that a supplier feed's EAN codes actually resolve before the products are published
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
Ask an agent to resolve a batch of unknown barcodes from a stock take and report which ones returned 404
Have an agent compare a customer's listed price against the store prices returned for the same barcode
Let an agent enrich missing catalogue attributes, with every lookup audited per tenant against that tenant's own key and quota
Example prompt
What product is barcode 0885909950805, and which stores list a price for it?
Set up Barcode Lookup in 4 steps
- 01Enable the Barcode Lookup connector from your fastn dashboard.
- 02Have each customer authorise their own Barcode Lookup account, so calls run under their credentials rather than a shared key.
- 03Decide which lookups, results and reports your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Barcode Lookup integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Barcode Lookup integration without building it. Your customers connect their own Barcode Lookup account inside your product and work their lookups, results and reports there, with no per-customer code on your side.
- Handle the part that actually costs time: these are metered read sources, so an uncached lookup on every page view burns the customer's allowance. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Barcode Lookup update is not your on-call problem.
- One integration serves your product and your agents. The same governed Barcode Lookup connection powers in-product features and gives AI agents scoped, audited access, so you answer questions from an authoritative outside source without holding that data yourself without wiring it twice.

SnowflakeBarcode Lookup integration FAQ
How do I add a Barcode Lookup integration to my product?
Enable the Barcode Lookup connector in your fastn dashboard, then let each customer authenticate their own Barcode Lookup account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Barcode Lookup client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Barcode Lookup account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Barcode Lookup account and only ever sees their own lookups, results and reports. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Barcode Lookup integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. Ask an agent to resolve a batch of unknown barcodes from a stock take and report which ones returned 404
Who maintains the Barcode Lookup integration?
fastn does. When Barcode Lookup changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Whose credentials does a Barcode Lookup lookup run under?
Each customer's own. Quota and cost land on the customer that caused them rather than on a shared key you have to meter and re-bill, and one heavy customer cannot exhaust another's allowance.
How should Barcode Lookup results be cached?
Per tenant, with a window that matches how fast the underlying data actually moves. Barcode Lookup is a read source rather than a system of record, so the same query returns the same answer until the source changes, and caching is the difference between a sustainable integration and one that exhausts a customer's allowance on a busy page.
What can I build with the Barcode Lookup integration?
A common starting point: let a customer connect their own Barcode Lookup account so scanned barcodes in your app resolve to product names and images under their own quota. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Barcode Lookup integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Barcode Lookup does not change your per-connector cost. You can start free with 3 connected accounts.
