## Which one, for what

### EasyPost (C)

Good for: An agent that quotes rates across carriers, buys a label, verifies an address, follows tracking by webhook and requests a refund from one merchant account, mainly on US carriers.

Ahead on:
- Agent ergonomics, 63 against 56
- Maintenance & community, 85 against 41

Watch for: No OpenAPI spec was found in the docs or in the EasyPost GitHub organisation. The reference is prose and tables, with a Postman workspace

### ShipBob (C)

Good for: An agent working for a merchant that already stores stock with ShipBob, to create and track orders, check inventory, book inbound stock and handle returns.

Ahead on:
- Reliability, 77 against 53
- Schema & documentation, 85 against 55
- Security & auth, 55 against 47
- Transparency & trust, 77 against 70

Watch for: No public price. Receiving, storage and pick, pack and ship fees come only in a quote from sales

## 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
