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.

ShipBob

OAuth with PKCE and read and write scopes per domain, a free sandbox, a public OpenAPI spec per version and a 24-month support window for each API version are documented. Fulfilment prices are by quote only, the status page has no API component, no official SDK was found, and Personal Access Tokens never expire and carry full account access.

Before you call either

EasyPost

  1. Use a test API key while building. It buys no postage and contacts no carrier, and test tracking codes simulate each tracking status
  2. 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
  3. 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
  4. Handle errors as either an array of objects or an array of strings. The docs say both shapes occur
  5. 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

ShipBob

  1. Call GET /2026-07/channel first and send the ID of the channel with _write scopes in the shipbob_channel_id header on every write
  2. Build against https://sandbox-api.shipbob.com with a sandbox account. Sandbox and production accounts, tokens and data are separate
  3. Set a stable reference_id on each order, product and return. A duplicate returns 422, which is the only guard against a double create
  4. Stay under 150 requests a minute per user and application, and wait the seconds given in x-retry-after after a 429
  5. Over MCP, writes work only on records in the channel created at consent. A 403 or 404 on a cancel usually means the record belongs to another channel
