Fulfillment

Fetch Shippo carrier rate quotes for this package

Required API key scope: fulfillment:read

Fetches real-time Shippo carrier rate quotes for a package. Delegates to fetchRatesForPackage in routes/shipping.mjs (THE ONE RULE). Requires a configured Shippo connector for the entity. Call this before POST /packages//buy-label to obtain a rate_object_id. Returns rates sorted by amount ascending (cheapest first). AUDIT-SKIP: read-only rate shop, no DB mutation.

Terminal orders are refused (409 order_not_spendable). Rate-shopping costs nothing at the carrier, but it mints the rate_object_id that a label purchase spends, so it is treated as spend-ARMING: if the package’s order is cancelled, archived, or expired, this returns 409 rather than handing back a spendable rate.
