# BridgesAgents > Catalog, price, stock and order links from retailers and service businesses of any segment (grocery, pharmacy, fashion, electronics, services, hotels, rentals, real estate visits...) for AI shopping agents, through MCP, REST, UCP and an ACP feed. The agent builds the cart; the consumer always confirms and pays the store directly on the order link. BridgesAgents never handles payment or card data. Everything below needs an agent key (`Authorization: Bearer abd_...`, free developer account) or a consumer OAuth connection, except the docs. ## Connect - [MCP server (Streamable HTTP)](https://api.bridgesagents.com/mcp): tools search_products, get_offers, get_promotions, search_properties, search_vehicles, get_store_portfolio, check_availability, quote_delivery, create_cart, get_cart, list_past_orders, reorder, request_quote, get_quote, respond_to_quote, respond_to_adjustment, open_issue, close_issue. Messages in pt, en or es with ?lang=en or ?lang=es. - [Developer sign-up and agent keys](https://bridgesagents.com/en/cadastro/desenvolvedor) - [REST API](https://api.bridgesagents.com/api/v1): same operations as the MCP tools. - [OpenAPI / Swagger](https://api.bridgesagents.com/swagger-ui.html) - [UCP discovery](https://api.bridgesagents.com/.well-known/ucp) - [Sandbox](https://sandbox.bridgesagents.com): test keys abd_test_, test stores and simulated orders. ## Docs - [Overview and concepts](https://bridgesagents.com/en/docs#visao-geral) - [Connect via MCP (Claude, ChatGPT, Cursor, mcp-remote)](https://bridgesagents.com/en/docs#mcp) - [MCP tools reference](https://bridgesagents.com/en/docs#tools) - [REST API](https://bridgesagents.com/en/docs#rest) - [Order webhooks](https://bridgesagents.com/en/docs#webhooks) - [Errors and limits](https://bridgesagents.com/en/docs#erros) ## Rules for agents - Never say a purchase was made: send the confirmUrl from create_cart or reorder and let the consumer confirm. - To pay, send that same order link ("check your order and pay"); never ask for card data in the chat and never send a payment link from anywhere else. - Do not ask for the consumer's phone in the chat: the confirmation page collects it. - Prices come with updatedAt; prescription products can't be bought through agents. ## Optional - [For retailers: put your store in front of AI agents](https://bridgesagents.com/en) - [Terms](https://bridgesagents.com/en/termos) and [Privacy](https://bridgesagents.com/en/privacidade)
