A client gem for working with the Population Growth API

An API client for the Purpose Platform

Ships the `portage` executable. `portage buy <url>` tries native UCP discovery first (zero credentials, works on any store that's opted in), falls back to a portage-ucp-* platform adapter only when this process already has that platform's own credentials in env (i.e. it's your own store or one you're integrated with), and otherwise says so plainly — never scrapes or session-hijacks as an anonymous shopper. `portage find` covers the no-URL case: ask an allowlist, DuckDuckGo, Brave, or a Google Programmable Search engine which stores might sell something, keep the ones answering /.well-known/ucp, and search their catalogs — documented APIs only, no SERP scraping. Depends on portage-ucp (for platform detection via Resolver), portage-ucp-client (for the actual buy calls), and portage-ucp-journal (for `portage-console`'s read-only view of local purchase/transaction/order state); no single adapter gem is a hard dependency. Ranking, escalation and the spend-policy check use portage-ucp core's rules; portage-ucp-decision is optional and only the opt-in confidence gate needs it.

Protocol-only core gem: Adapter contract, capability registry, manifest builder, and an MCP server wrapper. No commerce-backend deps.

Implements Portage::Ucp::Adapter against a BigCommerce store's v3 Catalog/Carts/Checkouts APIs and v2 Orders API. Generic only — no merchant-specific business logic. Plain Net::HTTP, no bigcommerce/api runtime dependency.

Every other portage-ucp gem lets a Ruby program expose a commerce backend to agents (server side). This gem is the other direction: connect to somebody else's /.well-known/ucp manifest, or drive your own Adapter directly, and place an order as the client. Three transports behind one interface (loopback over an in-process Adapter, stdio, Streamable HTTP) — callers never know which they got. Depends only on portage-ucp, the mcp gem's client half, and faraday (the HTTP transport's backend); no adapter gem is a dependency.

The judgment calls between the agent loop and the Adapter/client layer, as typed, inspectable decisions instead of control flow scattered across skill instructions and the CLI: which offer to pick (OfferRanking), hand off vs. keep going (EscalationPolicy), whether a result is confident enough to act on unattended (ConfidenceGate), and a typed wrapper around Portage::Ucp::PolicyGuard (PolicyCheck). See docs/plans/system-one-decision-layer.md.

Implements Portage::Ucp::Adapter against Etsy's Open API v3. Catalog and order are real; checkout is redirect-link only (links to etsy.com) since Etsy's public API has no cart/checkout endpoint. Generic only — no merchant-specific business logic. Plain Net::HTTP, no Etsy SDK runtime dependency.

Implements Portage::Ucp::Adapter against Meta's Graph API Commerce Catalog. Catalog is real; checkout is redirect-link only (to each product's own merchant-hosted URL) since Meta's public API has no cart/checkout endpoint for website-checkout catalogs, and none at all for native Instagram/Facebook checkout. Generic only — no merchant-specific business logic. Plain Net::HTTP, no Facebook SDK runtime dependency.

Implements Portage::Ucp::Adapter against a Magento/Adobe Commerce site's REST v1 API (admin-token catalog/order, anonymous guest-cart cart/checkout). Generic only — no merchant-specific business logic. Plain Net::HTTP, no Magento PHP SDK dependency.

Implements Portage::Ucp::Adapter against Shopify's Admin (catalog, order) and Storefront (cart, checkout) GraphQL APIs. Generic only — no merchant-specific business logic. Plain Net::HTTP, no shopify_api runtime dependency.

WebMCP as a transport, not a commerce backend. Inbound: registers a Portage-powered store's catalog/cart/checkout tools on the page via document.modelContext, each one calling back into the same Portage::Ucp::Mcp::Server every other transport uses. Outbound: a portage-ucp-client transport that discovers and calls the WebMCP tools any page registers, through whatever browser driver the caller already has (Ferrum, Playwright, Selenium, or a plain JS-evaluating callable). No adapter gem is a dependency.

Implements Portage::Ucp::Adapter against Wix's Stores (catalog) and eCommerce (cart, checkout, order) REST APIs. Generic only — no merchant-specific business logic. Plain Net::HTTP, no wix SDK runtime dependency.

Implements Portage::Ucp::Adapter against a WooCommerce site's Admin REST API v3 (catalog, order) and Store API v1 (cart, checkout). Generic only — no merchant-specific business logic. Plain Net::HTTP, no woocommerce-api runtime dependency.
