## 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 uk-taxi-phv-regulatory-decision-layer-authority-comparison-a80e08db -d '<json body>'
```

Example prompt: I'm applying for a private hire vehicle licence in England — can you compare Transport for London and Leeds City Council for my application? I have a clean driving record, a 2019 Toyota Prius, and I want to operate as an individual driver, not an operator.

## When to prefer this

Use this endpoint when an applicant, agent, or advisor needs to decide between two or more specific English taxi or PHV licensing authorities before committing to an application. It is distinct from a single-authority preflight because it is explicitly designed for multi-authority comparison with evidence-linked regulatory reasoning. Prefer it over generic regulatory lookup tools when you need a structured, actionable side-by-side assessment grounded in actual licensing criteria.

## Known failure modes

- Fewer than two authorities specified — returns validation error requiring minItems 2
- Unsupported or unrecognised authority name — returns error indicating authority is not in the supported set
- Missing or malformed applicant object — returns schema validation error
- Ambiguous applicant facts that cannot be mapped to regulatory criteria — may return partial or inconclusive assessments
- Payment not processed (x402) — request blocked before processing

## How this service works

Evidence-linked England taxi/private-hire licensing preflight and comparison MCP for AI agents.

## Output

A structured JSON response containing a status indicator and an array of per-authority assessment results, each providing evidence-linked regulatory analysis of how the applicant's facts map to that authority's licensing requirements, enabling direct comparison and an informed pre-licensing decision.
