aid: sellerx name: SellerX description: 'SellerX is a Berlin-based consumer-brand builder, founded in 2020, that acquires, operates and scales everyday consumer products into omnichannel global brands. Originally one of Europe''s largest Amazon FBA aggregators, it merged with KW Commerce in 2021 and with the US aggregator Elevate Brands in 2023, and has since repositioned itself from an aggregator into a brand builder. The group operates 20+ brands and 25k+ products across 10+ countries from hubs in Berlin, London, Manila and Dongguan, and has raised more than $750M in equity and debt from Sofina, L Catterton, Cherry Ventures, Felix Capital, 83North, an ADIA subsidiary, BlackRock and Victory Park Capital. SellerX sells consumer goods to consumers through marketplaces and its own channels; it publishes no public API, developer portal, SDK or machine-readable specification of its own.' url: https://raw.githubusercontent.com/api-evangelist/sellerx/refs/heads/main/apis.yml image: https://www.sellerx.com/logo.png x-type: company x-source: harvest:secondary-market specificationVersion: '0.23' created: '2026-08-05' modified: '2026-08-05' tags: - Company - E-Commerce - Consumer Brands - Retail - Amazon Aggregator - Marketplace Seller - Consumer Packaged Goods - Germany apis: - aid: sellerx:mcp name: SellerX MCP Server description: >- A live, remotely hosted Model Context Protocol server operated by SellerX at mcp.sellerx.com. The endpoint requires an OAuth 2.1 bearer token, so the tool manifest is auth-gated, but the server publishes RFC 8414 authorization-server metadata and RFC 9728 protected-resource metadata anonymously, along with a dynamic client registration endpoint and mandatory PKCE (S256). SellerX does not link to, document, or advertise this server anywhere on its corporate site; it was discovered through Certificate Transparency logs for sellerx.com. humanURL: https://mcp.sellerx.com/.well-known/oauth-protected-resource/mcp baseURL: https://mcp.sellerx.com/mcp tags: - MCP - Model Context Protocol - OAuth - Agents properties: - type: MCPServer url: mcp/sellerx-mcp.yml - type: Authentication url: authentication/sellerx-authentication.yml - type: OAuthScopes url: scopes/sellerx-scopes.yml maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io common: - type: DomainSecurity url: security/sellerx-domain-security.yml - type: Website url: https://www.sellerx.com/ - type: About url: https://www.sellerx.com/about/ - type: Products url: https://www.sellerx.com/brands/ - type: Careers url: https://www.sellerx.com/work-with-us/ - type: PrivacyPolicy url: https://www.sellerx.com/privacy-policy - type: Legal url: https://www.sellerx.com/imprint - type: GitHubOrganization url: https://github.com/kwcommerce - type: LinkedIn url: https://www.linkedin.com/company/seller-x - type: MCPServer url: mcp/sellerx-mcp.yml - type: Authentication url: authentication/sellerx-authentication.yml - type: OAuthScopes url: scopes/sellerx-scopes.yml - type: WellKnown url: well-known/sellerx-well-known.yml - type: Conformance url: conformance/sellerx-conformance.yml x-enrichment: date: '2026-08-05' status: enriched artifacts_added: 8 pass: local-v1 x-coverage: state: covered reason: null detail: >- SellerX runs a live remote MCP server at https://mcp.sellerx.com/mcp that it does not link or document anywhere public — it was found only through Certificate Transparency logs for sellerx.com. Its OAuth 2.1 discovery metadata (RFC 8414 + RFC 9728) is served anonymously and is captured verbatim, but the JSON-RPC tools/list manifest returns 401 invalid_token, so the tool set and its input schemas are auth-gated and deliberately not recorded. The corporate site publishes no API of any kind and answers HTTP 200 with an identical SPA body for every path, including nonexistent ones. evidence: - url: https://mcp.sellerx.com/.well-known/oauth-authorization-server status: 200 - url: https://mcp.sellerx.com/.well-known/oauth-protected-resource/mcp status: 200 - url: https://mcp.sellerx.com/mcp status: 401 - url: https://www.sellerx.com/openapi.json status: 200 checked: '2026-08-05'
