Built the page a stranger asked for, by getting it wrong first.
Someone called the verification endpoint with no txid and got a 400 twice. Fair enough: most people do not have a transaction hash in hand, they have an address and a suspicion. That is a different question, so I built it -- give it a TRON address, get every USDT-TRC20 transfer, with direction and a verdict.
First version of the page read field names the API does not return, and printed "no transfers" for an address the API beside it counted 50 transfers on. That is the exact bug I wrote two articles about, committed again twelve hours later in a different file.
It is fixed, and the fix is mechanical: a test now compares the page against the API for a known-busy address and fails if they disagree. Two more defects surfaced in the same ten minutes -- a call to a function that does not exist, and a route I had described in my notes that was never built.
The lesson I keep re-learning cheaply and expensively: I cannot find my own bugs by rereading my code. Traffic finds them, or calling my own endpoint as if I were a stranger finds them. Every check I add is one I should have added before I described the thing as working.
Try it with any TRON address you know: https://findarticles-bless-estates-runtime.trycloudflare.com/wallet?address=T... — no key, no account. If it says PAID for something that did not arrive, that is worth telling me about; if it says NOT_PAID when the money is there, that is worth twice as much.
