Glossary
Capture
A raw extraction output produced by Extract from a source URL. Captures preserve source-page product data in the original language, including images, options, SKUs, offers, identifiers, and capture-time aggregates such as price range and availability.
Credit
The shared unit of usage billing in Extralt. Credits are consumed by product-specific build actions: Extract uses 2 credits per successful product-page Capture, and Enrich uses 1 credit per Capture. The dashboard Agent and supported AI-assisted dashboard queries are included with an active subscription and do not consume credits.
See Credits & Billing.
Item
The page-grain output produced by Enrich from one Capture. Items carry normalized English product content, taxonomy, attributes, signals, option and size interpretation, selected media, identifiers, embedded normalized SKU commerce data, normalized review state, and lineage. Items are the durable normalization output and the input to Enrich's final materialization.
Listing
A store-specific source SKU identity produced by Enrich from Items. A Listing links a source URL, Store, identifiers, media, and observation lifecycle to one inferred Variant. The same Variant can appear as many Listings across Stores.
See the Product Taxonomy Explorer for the category and attribute structure used during enrichment.
Offer
An append-only seller, price, availability, and stock observation attached to a
Listing. Offers include price, compare-at price, currency, condition,
availability, seller identity and type, and categorical stock level. Variant
context is reached through the Listing. Current state is the complete set of
Offers for a Listing at its latest Extract run_started_at, not an arbitrary
latest row.
Organization
The top-level scope for all Extralt resources. Robots, schedules, runs, captures, credits, and API keys belong to an organization. Each org has its own subscription. Users can belong to multiple organizations.
See Account Setup.
Product
A canonical product family published by Enrich that groups sibling Variants. For example, multiple exact color and size configurations can be separate Variants under one Product. Products contain canonical content and taxonomy selected from Item evidence.
Review
A latest review aggregate attached to a Listing and Store. Final Reviews store compact normalized state: review count plus score on a 0-100 scale. Variant and Product context is reached through the Listing. Raw average and scale remain on Captures for audit.
Robot
A stable extraction resource for a specific host and country. Its status tracks creation of the internal crawler and scraper, and its ID remains the same from build through every Run. Completed Robots are reusable across multiple Runs.
See Extracting data.
Run
An extraction job that uses a robot to crawl start URLs and produce captures. Runs have a lifecycle (pending, running, completed, failed, stopped) and optionally a budget to limit credit usage. Runs can be created manually or by a schedule.
See Extracting data.
Schedule
A recurring extraction automation. Links a robot to a cadence (e.g. every hour, every day, every week) and automatically creates runs on that schedule. Schedules can be paused and resumed, and auto-pause when credits run out.
See Schedules.
SKU
A source-specific purchasable configuration extracted from a Capture. A SKU is the concrete thing a customer can buy on the source site: it has identifiers, stock, and one or more Offers. SKUs are merchant-specific and are not used as cross-store product identity.
Store
An organization-scoped host and country pair in the analytical model. Stores provide market and source context for Items, Listings, Offers, and Reviews. A Store is not a Robot, retailer group, or legal company.
Change
An append-only record of an observed semantic change. A Change names the entity, aspect, and action, retains the Run and observation time, and stores the before and after state as JSON evidence.
Enrichment
A processing job that reads Captures, writes one Item for each successfully processed Capture, then publishes the exact committed scope for Explore. Enrichments can be created, inspected, and stopped through the dashboard or public API. Stop prevents new credit spend while committed work finishes final preparation.
Variant
A canonical identity for one exact product configuration across stores. Variants are created by Enrich, can have many Listings, and are the cross-store matching unit used for price and availability comparison. Matching depends on the identifiers and product evidence available in the source data.
