## Which one, for what

### Ship24 (C)

Good for: An agent that only needs tracking events across many couriers, by webhook or by lookup, from a tracking number alone.

Ahead on:
- Security & auth, 37 against 32
- Maintenance & community, 80 against 73

Watch for: No status page was found. `status.ship24.com` doesn't resolve, and neither the site nor the docs link to one

### ShipStation API (C)

Good for: An agent working inside a merchant's existing ShipStation account (orders, batches, inventory, labels), or a developer who wants a free sandbox through the ShipStation API plans.

Ahead on:
- Reliability, 64 against 45
- Payments & pricing, 40 against 30
- Transparency & trust, 64 against 52

Watch for: One API key with full account access. No scopes, read-only keys or approval step before a label is bought

## 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
