Assessment: 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.

- Rate limits: 1,000 GET requests a minute. 100 POST, PATCH, PUT or DELETE requests a minute, burst 15 a second. 429 when exceeded
- Pagination: Cursor-based, `cursor` and `page_size` (up to 100 on shipments), with next and prev links in the HTTP Link header
- Errors: JSON:API error objects with `status`, `code` and `detail`. Synchronous announce responses carry carrier failures in an `errors` array

## Before you call it

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
