draconic21 Daily Agent Signal + x402 Data Tools is answering right now. Last checked 1 min ago. It exposes 57 tools.
Daily Agent Signal: x402 research; coverage varies. Free preview, $0.03 USDC on Base. SEC/OFAC.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 18 October 2026. No other catalogue keeps this.
A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.
