Verdicts
EasyPost
Docs written for agents (llms.txt, a Markdown copy of each page, a JSON page index), seven official SDKs and free test keys make the REST API easy to start on. 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.
ShippyPro
Two OpenAPI 3.1 files, a published limit of 20 calls per 10 seconds and a 99.5 per cent monthly SLA with service credits are public. API access needs an Enterprise plan arranged through sales, no changelog or SDK was found, and label creation on v1 has no idempotency key.
Before you call either
EasyPost
- Use a test API key while building. It buys no postage and contacts no carrier, and test tracking codes simulate each tracking status
- Don't blind-retry
POST /shipments/:id/buyafter a timeout. Retrieve the shipment first and check forpostage_label, since no idempotency key exists - 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
- Handle
errorsas either an array of objects or an array of strings. The docs say both shapes occur - Pass a scoped
carrier_accountslist when rating. Only the first 60 accounts are rated and the call doesn't fail when more are enabled
ShippyPro
- Send
Authorization: Bearer <API key>and POST a JSON body withMethodandParamstohttps://api.shippypro.com/v1/<Method>. Parameter names are case-sensitive - Check
StatusandErrorMessagein everyShipresponse. HTTP 200 withStatus2 means no label was created - Before retrying a failed
Shipcall, look the order up byTransactionID. v1 has no idempotency key, and each label counts against the plan - Test with the Generic carrier.
ShipandEditcalls on a real carrier create real labels - Stay under 20 calls per 10 seconds, and use webhooks for tracking. The docs advise against
GetTrackingin bulk
