Verdicts

Sendcloud

API v3 has 29 public OpenAPI 3.1 specs, an llms.txt index, a dated changelog and a hosted MCP server with toolset filtering. OAuth has one scope, api, so a credential can't be limited to reading. The changelog records response fields removed from tracking events on 25 September 2026 with no earlier deprecation entry.

Shippo

Per-label and per-call prices are public, test keys are self-serve, and the OpenAPI spec, llms.txt and Markdown docs are open to a fetch. 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.

Before you call either

Sendcloud

  1. Use API v3 at https://panel.sendcloud.sc/api/v3. The v2 create-parcel endpoint is closed to accounts created from April 2026
  2. Test with shipping_option_code sendcloud:letter (returns use sendcloud:letterreturn). Any other label is billed unless cancelled within the carrier's deadline
  3. Set external_reference_id on every shipment so a retry returns the existing shipment (409) instead of a second label
  4. Read the errors array on synchronous announce responses. A carrier failure can arrive inside a success status
  5. Connect MCP with ?toolsets=shipments,shipping-options,parcel-tracking,returns to keep the tool list short. Create and cancel tools act on the live account

Shippo

  1. Build and test with a shippo_test_ key. Test and live object IDs are separate, and the hosted MCP server has no test mode
  2. Send Authorization: ShippoToken <key>, not Bearer, and pin Shippo-API-Version: 2018-02-08
  3. Before retrying a failed POST /transactions, list recent transactions. There is no idempotency key, and a second purchase is a second charge
  4. Pass async: false on shipments and transactions, or poll the object until its status leaves QUEUED
  5. Set results on list calls (under 200). Defaults vary by resource, and list calls are limited to 50 a minute on live keys

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
