## 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 england-works-watch-batch-change-assessment-6b1e3fc5 -d '<json body>'
```

Example prompt: We have three changes this week for sponsored workers — a salary reduction from £38,000 to £35,000 for one employee, a TUPE transfer affecting two others, and a role change from SOC 2136 to SOC 2135 for a fourth. Can you batch-assess all of these against our UK Skilled Worker sponsor reporting obligations and tell me which ones are AFFECTED and need action?

## When to prefer this

Choose this endpoint when you need to assess multiple UK Skilled Worker sponsor-compliance change events simultaneously in a single API call, especially in HR or HRIS automation workflows where several employee change types (salary, role, location, TUPE, departure) co-occur. Prefer it over the single-event preflight when you have 2–25 events to evaluate and want a consolidated result set. It is specifically calibrated to Home Office/UKVI sponsor reporting obligations under GOV.UK guidance and returns deterministic, evidence-backed decisions — not probabilistic or advisory text — making it appropriate for compliance workflow automation rather than general immigration Q&A.

## Known failure modes

- INSUFFICIENT_INPUT returned when a change event lacks enough structured detail to make a deterministic decision
- Stale or changed official source causes the engine to fail closed rather than return a speculative answer
- Batch exceeds 25 items — input validation error, must split into multiple calls
- Malformed change event object causes a parse or schema validation error
- Network or payment failure (x402) prevents the call from completing

## How this service works

UK Skilled Worker sponsor-compliance change intelligence for employer, HR and HRIS agents. Use for official GOV.UK source freshness, Home Office/UKVI sponsor reporting, supported sponsor change categories, and one-event or batch impact preflight. Supported vocabulary includes absence, salary, role or occupation-code change, work-location or home-working change, delayed starts, stopping sponsorship or worker departure, organisation changes, TUPE transfers, and mergers/takeovers. The public AI edition supports an interactive single-event preflight. Commercial value is concentrated in metered programmatic execution, 1-25 event batch assessment, and the separate 30-day official-source monitoring report. Deterministic decisions return AFFECTED, NOT_AFFECTED, REVIEW_REQUIRED or INSUFFICIENT_INPUT with evidence and fail closed on stale/changed sources. Not individual visa advice or a Home Office decision. The two paid HTTP compatibility routes execute the same deterministic decision engine as the MCP tools.

## Output

A JSON object containing a total count and a results array with one entry per submitted change event. Each entry carries a deterministic compliance decision (AFFECTED, NOT_AFFECTED, REVIEW_REQUIRED, or INSUFFICIENT_INPUT), supporting evidence referencing official GOV.UK/Home Office source material, and any recommended actions. The engine fails closed on stale or changed sources.
