How this service works
Create a sniper watch: Stumble polls a public URL every 10 seconds for up to 48 hours and notifies your webhook within seconds of a condition becoming true (keyword, selector, JSON path, price, content change, HTTP status). One-time $2.00, no account needed. Ideal for drops and on-sale moments where seconds matter.
Output
Returns a watch ID confirming the sniper watch is active. While running, delivers near-real-time notifications to the specified webhook URL (or holds results for polling) the moment the condition is met — including matched content, the triggering URL, condition details, and timestamp. Polling stops as soon as the condition fires or the duration expires.
Example use cases
Sneaker drop instant alert
“Monitor https://sneakers.example.com/product/jordan-42 every 10 seconds for up to 48 hours and send a webhook to https://hooks.myapp.com/drop-alert the instant the keyword 'In Stock' appears on the page — I need to know within seconds.”
Price threshold alert for flash sale
“Watch https://store.example.com/api/products/987/price every 10 seconds for the next 48 hours and ping my webhook at https://hooks.myapp.io/price when the JSON path $.price drops below 49.99 — I want to catch the sale the moment it goes live.”
API endpoint recovery detection
“Poll https://status.myservice.com/health every 10 seconds for up to 24 hours and call my webhook at https://hooks.myops.com/recovered as soon as the HTTP status returns 200 — I need to know the instant the service comes back up.”
Technical details
Endpoint
POSThttps://stumble.vimabrosta.com/v1/watches/sniperWhen to prefer
Choose this endpoint over the standard watch (15-min polling) or fast watch (60-sec polling) when seconds matter — product drops, flash sales, or any event where missing the window by even a minute has real cost. It polls every 10 seconds for up to 48 hours, making it the highest-frequency, shortest-duration option in the Stumble suite. Best suited for single high-value detection events rather than long-running ongoing monitoring.
Side effects
- Target URL is unreachable or returns persistent errors — watch may exhaust duration without firing
- Invalid condition type or misconfigured JSON path/selector — condition never matches
- Webhook URL is unreachable — notification delivery fails silently
- Duration exceeds 2-day maximum — request rejected
- URL format invalid — request rejected at intake
- Payment of $2 USDC not completed — endpoint returns 402 and watch is not created
