# Domain Trust Score Change Watch

> Domain Trust Score Change 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).

Monitors a domain's trust/legitimacy score (0–100) over time and reports exactly what changed since the last check, including before/after field values.

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 domain-trust-score-change-watch-bde6def9
```

Example prompt: Keep an eye on example.com's domain trust score for me — check it regularly and let me know the moment the score or any of its legitimacy reasons change, along with what the values were before and after.

## When to prefer this

Choose this endpoint when you need to detect changes in a domain's trust or legitimacy score over time rather than just fetching the current score. Ideal for scheduled monitoring pipelines where you want precise field-level before/after diffs without managing your own state — the service stores the previous result for 90 days. Prefer it over a one-shot domain trust lookup when the goal is alerting or auditing score drift.

## Known failure modes

- Domain not provided or invalid — returns error indicating missing required parameter
- Domain not previously checked — no comparison available, returns current score with changed=false or null baseline
- Previous result expired (older than 90 days) — baseline purged, no before/after comparison available
- Domain unreachable or DNS failure — check may fail or return degraded score
- Payment not processed — x402 payment required before response is returned

## How this service works

Change watch for domain trust score: runs the check and compares it with the result from your previous call for the same domain (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 domain trust and legitimacy score 0-100 with the reasons changes. $0.01 per check.

## Output

Returns the current domain trust score (0–100) with legitimacy reasons, a boolean indicating whether anything changed since the last call, a list of exactly which fields changed with their before and after values, and a timestamp of when the domain was last seen. Previous results are retained for 90 days for comparison.
