ToolAssay

Pay once to register a price-threshold alert on any Base token

Pay once to register a price-threshold alert on any Base token. Supply target price, direction (above/below), and an https webhook URL. A polling cron (daily by default; configurable to ~minutes) checks DexScreener and POSTs your webhook when it crosses. Expires after 30 days. Or omit the webhook and poll with check=<id>: the verdict is THRESHOLD_MET, ok, FIRED, or unknown when the price feed could not be read.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
