Pay per request (MPP, no account)
Keyless requests (once the free daily lookup is used, and always for batch GET /v1/track?numbers=) answer 402 Payment Required with an MPP challenge. Pay and retry:
- $0.50 by card for a 25-number credit pack, returned as an
lsk_pack_…bearer token for later requests. - 2 cents per tracking number in USDC on Tempo.
See Pay per request.
Accounts
Every account starts on Free. Upgrade, change the card or cancel under Billing in the dashboard.
What counts
A tracking number counts when you look it up: /v1/track, or the MCP tools track_package and track_packages.
- Free: every number in every request counts, including repeats and cached answers.
- Pro: a number counts once per billing period, however often you look it up, and only if the carrier answered (a result or
not_found). Lookups that fail on our side (carrier_error, timeouts) are free.
GET /v1/account returns dailyLimit and usedToday. GET /v1/usage?days=30 returns per-day lookups and live (sent to the carrier rather than cache).
At the limit
A request that would go past the daily limit is refused whole with 429:
{ "error": { "code": "rate_limited", "message": "Daily Free tier limit of 5 tracking numbers reached (resets at 00:00 UTC). Upgrade to Pro at https://app.lastscanned.com for $4.99/mo (1,000 unique numbers a month included, no daily limit, re-checking a number is free) or pay per request without a key over MPP." } }A batch of 10 numbers with 3 left today is refused; nothing in it is looked up. Refused requests don't count.
rate_limited also comes back for single numbers when Spee-Dee is throttling us; retry those in a minute.
