Use this instead of hard-coding market lists — markets are added over time. ## OpenAPI ````yaml /api-reference/openapi.yaml get /channels openapi: 3.1.0 info: title: Unif API version: '2026-09-01' summary: One schema for commerce data across every channel. description: > The Unif API returns normalized commerce data — shops, products, creators, videos, livestreams and categories — through a single schema that does not change when the underlying data source does. Each request runs a cascade across the sources behind a channel, in cost order, stopping at the first result that verifies. You are charged for the hit, not for the attempts. See [the waterfall](/docs/concepts/waterfall). Every response is denominated in the currency you ask for, scoped to a market, and measured over a period you control, whichever source answered. **Base URL** ``` https://api.unif.dev/v1 ``` All requests require a bearer token. See [Authentication](/docs/authentication). **Conventions** - Success and failure are carried by the HTTP status code. There is no envelope to unwrap: a `200` body is the object itself, and any `4xx` or `5xx` body is an [error object](/docs/platform/errors). - Lists are cursor-paginated. Read `next_cursor` and stop when `has_more` is false. - Every response carries `X-Request-Id`. Billable responses also carry `X-Unif-Credits-Charged` and `X-Unif-Credits-Remaining`. - Monetary fields are converted to the `currency` you request, and every object repeats the `currency` and `period` it was measured under. contact: name: Unif Support email: support@unif.dev url: https://unif.dev/docs license: name: Proprietary url: https://unif.dev/legal/terms servers: - url: https://api.unif.dev/v1 description: Production security: - bearerAuth: [] tags: - name: Meta description: Workspace, channel availability and field coverage. - name: Shops description: Storefronts and sellers. - name: Products description: Listings, pricing and sales performance. - name: Creators description: Affiliates and influencers who sell. - name: Videos description: Short-form video attributed to sales. - name: Livestreams description: Live selling sessions. - name: Categories description: The normalized category tree and category-level market data. - name: Resolution description: Turn a URL, handle or external ID into a Unif entity. - name: Jobs description: Asynchronous work for large searches, enrichments and exports. - name: Lists description: Saved sets of entities. - name: Trackers description: Scheduled re-checks that emit webhook events on change. - name: Webhooks description: Endpoint registration and delivery settings. - name: Usage description: Credit balance and per-request consumption. paths: /channels: get: tags: - Meta summary: List channels and markets description: > Lists the channels available to your workspace and the markets each one covers.
