Verdicts

Ship24

The REST API and the hosted MCP server share one public OpenAPI 3.1 spec, numbered rate limits with Retry-After, and tracker creation that is idempotent by payload. No status page, SLA or security certification was found, API keys carry no scopes, and the API agreement and data processing agreement named in the terms aren't published.

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.

Before you call either

Ship24

  1. Send Authorization: Bearer apik_... to https://api.ship24.com/public/v1. The same key works on the MCP server, which lists tools without a key but answers 401 on calls
  2. Store the trackerId or set a unique clientTrackerId. Tracking numbers aren't unique, and any changed field on a repeat POST /trackers creates a second tracker that uses quota
  3. Allow up to 60 seconds for the first POST /trackers/track or POST /tracking/search call, since results are fetched from the courier synchronously
  4. Cache GET /couriers. It is limited to one request a second and returns the whole courier list, and courier auto-detection usually makes courierCode unnecessary
  5. Check for quota_limit_reached and no_active_subscription. POST /tracking/search needs a separate per-call plan, and the free plan blocks at 10 shipments a month

ShipStation API

  1. 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
  2. Call GET /v2/carriers first. Rate and label calls need carrier_ids or a carrier_id and a service_code from that account
  3. Don't blindly retry POST /v2/labels after a timeout. List labels first, then void a duplicate with PUT /v2/labels/{label_id}/void
  4. Check the errors array on 2XX responses too, and read error_source to tell a carrier fault from a ShipStation one
  5. On a platform (Standard or Premium) key every label is real and charged. Ask the owner before buying, and void test labels at once
