One-shot look at a source. No watch is created. Types: url (current page text), rss (latest feed items), price (current USD price), edgar (recent SEC filings — 8-K item codes decoded, Form 4 insider trades parsed into who bought/sold, how much, and whether scheduled). To keep watching, POST /watches with the same body.
# 1. Ask the endpoint what it costs (no payment, no wallet needed): curl -i -X GET 'https://longwatch.dev/check' # -> HTTP/1.1 402 Payment Required # the response carries the price, asset and pay-to address. # 2. Pay and retry with any x402 client: npx x402-fetch 'https://longwatch.dev/check'
Endpoint: https://longwatch.dev/check. Operated by longwatch.dev, not by Animica. Price and availability were correct at the last probe on 2026-09-02 and are set by the operator, who may change them.
Poll a watch for alerts since a cursor. Pass since={last seq you saw}; the response carries a new cursor. Polling keeps the watch alive.
