check_now
Look at a source right now
This-session snapshot only — 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) — 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 — no wallet needed.

create_watch
