Spree API v3

Before writing code

Fetch live docs:

1. Fetch https://spreecommerce.org/docs/api-reference for the v3 API index.
2. Fetch the OpenAPI spec for the Spree version you target — it ships per release. Find the link on the API reference page.
3. Fetch the v5.4 announcement (https://spreecommerce.org/announcing-spree-commerce-5-4/) for the design rationale.
4. Inspect the live Spree source under app/controllers/spree/api/v3/ for the canonical request/response shape per endpoint.
5. Check the rate-limit configuration in config/initializers/spree.rb for the deployment you're targeting.
