What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks β the operator of longwatch.dev controls every word below.
Look at a source right now
This-session snapshot only β no watch, no cursor. Use when you will not come back. Required by type: url/rss/x402 need url; price needs coin plus above, below, or move_pct_24h; edgar needs ticker or cik. 8-K items are decoded, Form 4 trades parsed, and x402 probes validate the unpaid 402 challenge without sending payment. If the job spans runs, create_watch instead and persist watch_id + key. Costs $0.001 USDC per call via x402 (Base) β no API key, no account. Calling without payment returns 402 with the payment requirements. Free alternative: GET https://longwatch.dev/demo for a free NVDA Form 4 sample, or POST https://longwatch.dev/try for a 24h watch β no wallet needed.

Create a standing watch
Keep watching a source between agent runs and alert when it changes. Persist watch_id and key; later poll_alerts with since=<last cursor> returns only what you missed.
