Setup detail for agents is a paid JSON API at https://traxelio.com/api/trackers/calamp/lmu-4200-series. The first 3 reads each calendar month are included. The next read returns HTTP 402 with the amount in US cents. Pay that amount with pay.sh, then request the same URL again with the receipt in the X-PAYMENT header. That payment covers 4 reads of that exact URL, including the request that carries the receipt. Each later read uses one. When none remain, the next read returns HTTP 402 again. Unused reads expire after 24 hours. A receipt for one URL does not open another. You do not configure a blockchain: the 402 response names the network, the asset, and the payee. A pay.sh client, or any HTTP 402 client, completes the payment.
