  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 9

track17_change_carrier

WRITE: assign a different carrier to registered tracking numbers (up to 10 per call), for example when auto-detection picked the wrong one. A number can change carrier at most 5 times, and a successful change can be charged as one shipment (see track17_get_quota). POST /changecarrier.

Discovered
track17_change_tag

WRITE: set the tag (your own label, max 100 characters) of a registered tracking number. It replaces the old tag. Free. POST /changeinfo.

Discovered
track17_get_quota

The account's tracking quota: total, used, remaining, used today, the daily registration limit (0 = no limit) and the free e-mail quota. Each registered tracking number uses 1 quota. POST /getquota.

Discovered
track17_get_tracking

Full tracking details (status, sub-status, milestones, every carrier event with time and location, estimated delivery) for up to 10 numbers that are ALREADY registered on this account. Free: it does not use quota. A number that is not registered comes back in `rejected` — register it first with track17_register_numbers, or use track17_realtime_lookup. POST /gettrackinfo.

Discovered
track17_list_tracking_numbers

Search the tracking numbers registered on this account (40 per page) with their carrier, status, registration and last-update times, and latest event. Filter by number(s), carrier, tracking state, package status or registration date. Free: it does not use quota. POST /gettracklist.

Discovered
track17_realtime_lookup

WRITE (uses quota): look up ONE tracking number directly at the carrier right now, without registering it. Costs 1 quota per call (standard: carrier data up to 3 hours old). If the number is already registered, a changed result is also pushed to the account. Not supported for USPS, Royal Mail, Australia Post, Direct Freight Express, DHL eCommerce US and DHL Global Forwarding; some accounts are not enabled for real-time lookups. POST /getRealTimeTrackInfo.

Discovered
track17_register_numbers

WRITE (uses quota): start tracking up to 10 tracking numbers per call. Each ACCEPTED number costs 1 quota from this account (see track17_get_quota); rejected numbers cost nothing. Deleting and re-registering a number costs again. 17TRACK then updates the status itself every 6-12 hours; read it with track17_get_tracking. The carrier is detected automatically unless a carrier code is given. No e-mail notifications are enabled. POST /register.

Discovered
track17_retrack

WRITE: restart tracking of stopped numbers (up to 10 per call). Each number can be restarted only ONCE in its lifetime, so a second restart is rejected. POST /retrack.

Discovered
track17_stop_tracking

WRITE: stop tracking registered numbers (up to 10 per call). The numbers stay in the account for 90 days with their history and can be restarted ONCE each with track17_retrack. Stopping does not refund quota. POST /stoptrack.
