lineofflight/peddler: Amazon Selling Partner API (SP-API) in Ruby

Peddler is a Ruby interface to the Amazon Selling Partner API (SP-API). The SP-API enables Amazon sellers and vendors to programmatically access their data on orders, shipments, payments, and more. Peddler is automatically generated from the latest Open API models provided by Amazon. A nightly job tracks Amazon's spec changes, so new endpoints and fields land shortly after Amazon publishes them. Model changes are not considered breaking and don't trigger a major version bump. Peddler covers all SP-API endpoints, reports, notifications, and feeds. It's also lightweight: thanks to Zeitwerk, only the code you use gets loaded.
