No OpenAPI spec or idempotency keys were found, every key has full account access, and the status page shows a connectivity outage on 23 July 2026 that affected all operations.\n\n**ShipStation API.** A public OpenAPI 3.1 contract with 173 operations, Markdown docs for agents and a free ShipStation API plan with a sandbox make a first rate quote or test label reachable without a contract. One API key carries full account access, with no scopes, read-only mode or idempotency keys on label purchases.\n\n## Before you call either\n\n### EasyPost\n\n1. Use a test API key while building. It buys no postage and contacts no carrier, and test tracking codes simulate each tracking status\n2. Don't blind-retry `POST /shipments/:id/buy` after a timeout. Retrieve the shipment first and check for `postage_label`, since no idempotency key exists\n3. Send the API key as the HTTP Basic username with an empty password on the REST API, and as a Bearer token on the MCP server\n4. Handle `errors` as either an array of objects or an array of strings. The docs say both shapes occur\n5. Pass a scoped `carrier_accounts` list when rating. Only the first 60 accounts are rated and the call doesn't fail when more are enabled\n\n### ShipStation API\n\n1. Send the key in an `API-Key` header to https://api.shipstation.com/v2. A key that starts `TEST_` runs in the sandbox on the same host\n2. Call GET /v2/carriers first. Rate and label calls need `carrier_ids` or a `carrier_id` and a `service_code` from that account\n3. Don't blindly retry POST /v2/labels after a timeout. List labels first, then void a duplicate with PUT /v2/labels/{label_id}/void\n4. Check the `errors` array on 2XX responses too, and read `error_source` to tell a carrier fault from a ShipStation one\n5. On a platform (Standard or Premium) key every label is real and charged. Ask the owner before buying, and void test labels at once\n\n## Questions\n\n### Which is better for AI agents, EasyPost or ShipStation API?\n\nShipStation API scores 59.3 (C) on agent readiness against EasyPost's 54.3 (C), and leads in 4 of 7 scored categories. EasyPost leads on security \u0026 auth, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do EasyPost and ShipStation API need an API key?\n\nBoth need an API key.\n\n### Can an agent call EasyPost and ShipStation API without installing anything?\n\nYes.
