Hosted Product Feed URLs: Why They Matter
> Hosted product feed URLs are stable, CDN-backed web addresses that serve a merchant's product feed files — generated and maintained by FeedBridge — allowing AI platforms, shopping channels, and marketplaces to fetch current product data directly from a reliable URL without requiring manual file uploads or custom server infrastructure from the merchant.

What Are Hosted Product Feed URLs?
A hosted product feed URL is a persistent web address at which a merchant's product feed file is served — accessible to any system that needs to read the feed, on demand or on a schedule. "Hosted" means that the feed file is stored and served from infrastructure maintained by the feed provider (in this case FeedBridge), not from the merchant's own server or e-commerce platform. "CDN-backed" means the feed is distributed through a Content Delivery Network — a geographically distributed network of servers that caches and serves content from locations close to the requesting system, ensuring fast and reliable delivery regardless of where the AI platform or marketplace is hosted.
In the context of product feeds for AI commerce, a hosted URL solves a fundamental operational problem: AI platforms, shopping channels, and marketplaces all need a reliable, current, and accessible source for a merchant's product data. Without hosted URLs, merchants must either manually upload feed files each time the catalog changes, maintain their own server infrastructure to serve feed files, or rely on their e-commerce platform's native feed export — which may not support AI-specific formats like ACP JSON-LD or UCP-compliant output. Hosted feed URLs eliminate all three constraints: the file is always available at the same address, always current within the configured refresh schedule, and requires no server infrastructure from the merchant.
FeedBridge provides CDN-backed hosted feed URLs as a live feature, unique per brand, for all five feed formats it generates: ACP JSON-LD, UCP Interactive Protocol, Google Merchant Center CSV, Meta Commerce Manager CSV, and Amazon Inventory File TSV. Every brand on FeedBridge gets a dedicated set of stable feed URLs — one per format — that remain constant regardless of catalog changes, enrichment updates, or scheduling configuration changes.

Why Stable Feed URLs Matter for AI Commerce
The stability of a feed URL — its persistence at a consistent, unchanging address — is more important in AI commerce than in traditional shopping feed workflows. There are three reasons for this.
AI platform registration is a one-time setup. When a merchant registers their ACP JSON-LD feed URL with ChatGPT Shopping, or their GMC CSV URL with Google Merchant Center, that URL registration is a one-time configuration step. If the URL changes — because the merchant moved their feed file to a different server, changed their feed provider, or reconfigured their export path — the registered URL breaks. The AI platform can no longer fetch the feed, and the merchant's products disappear from the surface until the URL is re-registered. A stable hosted URL at a permanent address means this registration is done once and never needs to change.
AI agents query feeds on their own schedule. Unlike traditional shopping feeds where the merchant pushes updates to the platform, AI platforms typically pull product data from the merchant's registered feed URL on their own schedule — polling the URL periodically to check for updates. This means the URL must be reliably accessible at any time, not just during business hours or when the merchant's server is under light load. CDN delivery ensures the feed is available and responsive regardless of when the AI platform's crawler requests it.
Feed freshness signals catalog credibility. An AI platform that consistently gets successful, current responses from a merchant's feed URL develops a reliable data relationship with that merchant. A feed URL that returns errors, serves stale content, or is intermittently unavailable signals unreliable data — which can affect how the platform prioritises and trusts the merchant's product data. Hosted CDN-backed URLs provide the consistent, reliable delivery that supports a credible data relationship between the merchant and the AI platform.

How FeedBridge Hosts Feed URLs
FeedBridge's feed hosting infrastructure generates and serves five hosted feed URLs per brand — one for each supported feed format. The hosting architecture has several characteristics that directly support AI commerce reliability:
CDN-Backed Delivery
All FeedBridge hosted feed URLs are CDN-backed. The feed files are cached and served from the CDN rather than directly from FeedBridge's application servers, providing geographically distributed delivery. This means an AI platform querying a FeedBridge-hosted feed URL receives the response from a CDN node close to its infrastructure, reducing latency and improving response consistency.
Unique URLs Per Brand
Each brand on FeedBridge has its own dedicated set of feed URLs, distinct from every other brand's URLs. This means:
- Feed URLs are not shared or proxied across merchants — each URL serves exactly one brand's product data
- A merchant's feed URL cannot conflict with or be affected by another merchant's feed activity
- The URL is a persistent, brand-specific identifier that AI platforms can treat as a stable data source
All Five Feed Formats Hosted
FeedBridge hosts a dedicated URL for each of the five feed formats it generates:
| Feed Format | Channel | |---|---| | ACP JSON-LD | ChatGPT Shopping, ACP surfaces | | UCP Interactive Protocol | Google AI Mode (REST endpoints) | | Google Merchant Center CSV | Google Shopping, Google AI Mode | | Meta Commerce Manager CSV | Facebook Shops, Instagram Shopping | | Amazon Inventory File TSV | Amazon Seller Central (US) |
Each format URL serves the same underlying product catalog in its channel-specific format and structure. Changes to the product catalog — new products, price updates, enrichment improvements, availability changes — are reflected across all five hosted feed URLs at the next scheduled refresh.

Feed Scheduling and URL Currency
A hosted feed URL is only as valuable as the data it serves. A stable URL that serves stale product data — with prices, availability, or catalog composition that no longer reflects the merchant's actual inventory — creates problems at the downstream surface: product pages that fail to load, prices that differ from checkout, or out-of-stock products that still appear as available.
FeedBridge's feed scheduling feature addresses this through configurable auto-refresh intervals. Merchants can set the feed refresh frequency to match their catalog change rate — more frequent refreshes for merchants whose prices and inventory change daily, less frequent for merchants with stable catalogs. When the refresh interval triggers, FeedBridge regenerates all feed files from the current product catalog state and updates the CDN-cached content at the hosted URLs. The URL itself does not change; only the content served at that URL is updated.
This scheduling model creates a key operational pattern: the AI platform registers the feed URL once, the merchant configures the refresh interval once, and the feed stays current automatically without either party needing to take further action. The hosted URL serves as the perpetual connection point between the merchant's live catalog and the AI platform's product data system.

Feed Health Monitoring and URL Reliability
Hosting a feed at a stable URL addresses delivery; feed health monitoring addresses data quality. FeedBridge's feed health monitoring feature continuously checks all hosted feed URLs for:
- Dead product URLs: Product page links within the feed that return errors (404, redirect loops, timeout), indicating that the merchant's product pages are no longer accessible at the linked addresses
- Feed validity: Whether the feed file structure and field formats conform to the relevant channel's specification — a malformed field in the ACP JSON-LD feed or an incorrectly formatted price value in the GMC CSV will be detected
- Stale feed state: Whether the feed has been successfully refreshed within the expected interval — detecting cases where a scheduled refresh failed to complete

Hosted URLs vs Manual File Upload
The contrast between hosted feed URLs and manual file upload workflows illustrates the operational value of hosted delivery:
| Dimension | Hosted Feed URLs | Manual File Upload | |---|---|---| | Catalog update workflow | Automatic at scheduled refresh interval | Manual: download, export, upload to each channel | | URL stability | Permanent; registered once per channel | New file path each upload; re-registration may be needed | | Multi-channel delivery | All five formats updated simultaneously | Separate upload workflow per channel | | Feed freshness | Controlled by configurable refresh schedule | Dependent on merchant's manual upload frequency | | Error detection | Feed health monitoring with email alerts | Relies on channel's own validation feedback | | Infrastructure required | None (FeedBridge-hosted) | Merchant must manage file storage and delivery |
For merchants managing catalogs of any scale — or distributing across multiple channels simultaneously — manual file upload is an operationally fragile workflow. A price change that affects 500 products requires regenerating and re-uploading five separate feed files to five channels. With hosted feed URLs and configurable scheduling, the same price change is reflected in all five channel feeds at the next refresh, with no manual upload step.

Hosted Feed URLs and the UCP Manifest
For merchants implementing the Universal Commerce Protocol, the hosted feed URL concept extends beyond static file delivery to the UCP manifest endpoint. FeedBridge generates the machine-readable UCP manifest at the `.well-known/ucp` path, declaring the merchant's live UCP capabilities — Catalog Search, Catalog Lookup, Cart, and Identity Linking endpoints — to AI agents that discover the manifest.
Like the static feed URLs, the UCP manifest is hosted by FeedBridge at a stable address. AI agents querying a merchant's UCP capabilities read the manifest to discover which endpoints are live, then interact with those endpoints in real time. The manifest's stability is as important as a feed file's stability: an agent that registered the manifest URL during initial capability discovery needs that URL to remain consistent for subsequent interactions.
FeedBridge's UCP Dashboard Hub provides a compliance scorecard and capability checklist that reflects the current state of the merchant's UCP endpoints — giving merchants visibility into which UCP capabilities are live and correctly configured alongside their static feed URL health.

Why It Matters for Merchants
Hosted feed URLs are the delivery infrastructure that connects a merchant's product catalog to every AI shopping and e-commerce channel simultaneously. Without reliable hosting, the best-enriched product data in the world cannot reach the AI platforms and marketplaces that need it. A feed URL that returns errors, serves stale data, or changes address is a broken data pipeline — one that silently removes the merchant's products from AI surfaces without any visible error on the merchant's end.
For merchants who are investing in AI enrichment — building intent tags, Q&A pairs, persona arrays, and trust signals into their product records — hosted feed URLs are how that investment reaches the channels where it matters. The enriched ACP JSON-LD feed at the hosted URL is what ChatGPT Shopping reads when evaluating whether to recommend the merchant's products. The current GMC CSV at the hosted URL is what Google Merchant Center uses to approve and index product listings for Google AI Mode.
Hosted delivery is not a technical detail — it is the last mile of product data distribution, and its reliability determines whether the enrichment and compliance work done upstream translates into actual product visibility on AI commerce surfaces.

Frequently Asked Questions
Q: Does the hosted feed URL change when I update my product catalog? A: No. The hosted feed URL is permanent and does not change when products are added, updated, or removed. Only the content served at that URL changes — at the next scheduled refresh, the updated catalog state is regenerated and the CDN-cached content is updated. The URL itself remains stable, so AI platform registrations and channel configurations do not need to be updated when the catalog changes.
Q: How do I register my FeedBridge hosted feed URL with a channel like Google Merchant Center or ChatGPT Shopping? A: Registration is a one-time setup step performed in each channel's product data management interface. For Google Merchant Center, you add the FeedBridge GMC CSV URL as a scheduled fetch source in Merchant Center's "Feeds" section. For Meta Commerce Manager, you register it as a URL-based data source in Commerce Manager. For ChatGPT Shopping and other ACP surfaces, the ACP JSON-LD URL is registered in the AI platform's merchant data settings. Each channel's registration UI differs, but the process is consistent: copy the FeedBridge-hosted URL for that format and enter it as the feed source URL in the channel.
Q: What happens if a scheduled feed refresh fails? A: FeedBridge's feed health monitoring detects when a scheduled refresh has not completed within the expected window and flags the feed as stale. The feed alert preferences system then sends an email notification to the merchant. The previously generated feed content remains available at the hosted URL until the next successful refresh — so the channel continues to receive product data, but from the last successful generation rather than the current catalog state.
Q: Can I have different refresh schedules for different feed formats? A: FeedBridge's feed scheduling feature supports configurable auto-refresh intervals. The specific granularity of per-format schedule configuration is managed within FeedBridge's feed scheduling settings. For merchants whose Amazon catalog update frequency differs from their GMC or ACP update frequency, the scheduling configuration accommodates different feed delivery requirements.
Q: Is there a separate hosted URL for each feed format, or one URL for all formats? A: FeedBridge provides a separate hosted URL for each feed format per brand. The ACP JSON-LD feed, GMC CSV, Meta CSV, and Amazon TSV each have their own distinct URL. This is necessary because each format is structured differently and serves a different channel — the same URL cannot serve both a JSON-LD file and a CSV file to different consumers simultaneously.
