Label purchase has no idempotency key, API keys carry no scopes, and the status page logged carrier-side incidents on most days between July and October 2026.\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### Shippo\n\n1. Build and test with a shippo_test_ key. Test and live object IDs are separate, and the hosted MCP server has no test mode\n2. Send `Authorization: ShippoToken \u003ckey\u003e`, not Bearer, and pin `Shippo-API-Version: 2018-02-08`\n3. Before retrying a failed POST /transactions, list recent transactions. There is no idempotency key, and a second purchase is a second charge\n4. Pass `async: false` on shipments and transactions, or poll the object until its status leaves QUEUED\n5. Set `results` on list calls (under 200). Defaults vary by resource, and list calls are limited to 50 a minute on live keys\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, Shippo or ShipStation API?\n\nShippo scores 61.9 (C) on agent readiness against ShipStation API's 59.3 (C), and leads in 2 of 7 scored categories. ShipStation API leads on reliability.\n\n### Do Shippo and ShipStation API need an API key?\n\nShippo takes an API key or an OAuth sign-in. ShipStation API needs an API key.\n\n### Can an agent call Shippo and ShipStation API without installing anything?\n\nYes. Shippo has a hosted endpoint at https://api.goshippo.com and ShipStation API at https://api.shipstation.com/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/shippo-vs-shipstation.json, and with the fewest tokens: https://www.anchorterminal.com/compare/shippo-vs-shipstation.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"shippo\", \"b\": \"shipstation\"}`.
