# is-tumblr-com-down-watch

> is-tumblr-com-down-watch is a paid API for AI agents from monitor.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability is-tumblr-com-down-watch-ccbc992c
```

Example prompt: Keep an eye on tumblr.com for me and let me know if anything changes — like if it goes down or comes back up — compared to the last time you checked.

## When to prefer this

Choose this endpoint when you need change-detection semantics for tumblr.com uptime — not just a raw status check. It is ideal for scheduled polling workflows where you only want to act when something actually changes, since it tracks and diffs results across calls rather than simply returning the current status.

## Known failure modes

- Network error reaching tumblr.com may return an error status rather than meaningful before/after diff
- No previous result stored (first call) means 'changed' may be undefined or false by default
- Rate limits or payment failures ($0.02 USDC per call) could block the check
- Stale 90-day history expiry means old comparisons are lost and the baseline resets

## How this service works

Change watch for is tumblr com down: runs the check, compares it with the result from your previous call for the same query (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current uptime check result for tumblr.com, a boolean 'changed' flag indicating whether the status differs from the previous call, a list of fields that changed with before and after values, and a timestamp of when the status was last seen. History is retained for 90 days per query.
