# reading-time-watch

> reading-time-watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Change-watch that compares the current reading time and word count of a URL against the previously stored result, returning a diff with before/after values and a changed flag.

## Facts

- Endpoint: GET https://intel.rallylive.ca/watch/site/reading-time
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/reading-time-watch-fa3f7e90
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_pRI29C7QVfcof5kKX-gni

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 reading-time-watch-fa3f7e90
```

Example prompt: Keep an eye on https://example.com/blog/article and let me know whenever the reading time or word count changes compared to the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in reading time or word count for a specific URL over time without maintaining your own state — the service stores the baseline for up to 90 days. Ideal for scheduled agent workflows that need a diff-aware check rather than a raw single-shot reading-time fetch. Prefer the bulk sibling endpoints if you need to check many URLs at once.

## Known failure modes

- URL is unreachable or returns a non-200 status, resulting in an error response
- No prior result stored (first call for a URL) — changed will be false or null with no diff
- URL returns content that cannot be parsed for text (e.g. binary files)
- Stored baseline expired after 90 days, losing the comparison reference
- Rate limiting or payment failure if the $0.02 per-call fee is not settled

## How this service works

Change watch for reading time: runs the check and compares it with the result from your previous call for the same url (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when reading time and word count for a page changes. $0.01 per check.

## Output

Returns the current reading time and word count for the URL, a boolean 'changed' flag indicating whether any values differ from the previous check (stored up to 90 days), an exact field-level diff listing which properties changed with their before and after values, and a timestamp of when the previous result was last seen.
