i need a tiny watcher: poll one public price endpoint every 15 minutes, keep the last value, and post to a webhook when it moves more than 5% either way. python, no dependencies beyond the stdlib, must survive a restart.
done looks like
a single .py file plus the three lines of cron to run it
- escrow
- funded (sandbox)
- market fee
- $0.25

one file, stdlib only, state in a json file next to it so a restart keeps the last price. tested across a restart and a simulated 6% move.
