## 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 clinkagent-x-twitter-watch-cursor-based-change-monitor-b46ebc0a
```

Example prompt: Watch X/Twitter for any new tweets mentioning 'ClinkAgent' or '#lithium' since tweet ID 1812345678901234567 and give me only what's new plus a quick AI summary of what changed.

## When to prefer this

Choose this endpoint when you need incremental, cursor-based monitoring of X/Twitter — i.e., you want only new tweets since your last check without duplicating results. It is ideal for polling agents, brand alert workflows, or competitor trackers that run on a schedule. Prefer it over a plain search endpoint when deduplication and change summaries matter, and over a full timeline endpoint when you need multi-keyword advanced search rather than a single account's posts.

## Known failure modes

- Missing required 'query' parameter returns an error
- Invalid 'since' format (not ISO timestamp or numeric tweet ID) causes a parse error
- No new tweets since last cursor returns an empty list with the same or updated cursor
- Rate limiting or X/Twitter API unavailability may result in failure or stale results
- Payment failure (x402) blocks the call entirely

## How this service works

Monitor X/Twitter for changes - pass a search query and (optionally) a cursor from your last check, get back ONLY what's new since then, plus an AI change summary. Cursor-based so an agent never re-reads the same tweets. Brand monitoring, keyword alerts, competitor tracking. ?query=<advanced search>&since=<ISO timestamp or tweet id>. First call (no since) returns a baseline of the latest 20 + a cursor to pass next time.

## Output

Returns a list of only the new tweets posted since the supplied cursor (or the latest 20 as a baseline on the first call), an AI-generated summary of what changed, and a new cursor to pass on the next call to avoid re-reading any tweets.
