## 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-ecb93963 -d '<json body>'
```

Example prompt: Can you run a preflight check on whether I qualify for a private hire vehicle licence with Transport for London — I'm 28 years old, I've held my driving licence for 4 years, and I do have a Pass Plus certificate?

## When to prefer this

Use this endpoint when you need a fast, structured, evidence-linked preflight eligibility check against a specific England taxi or PHV licensing authority before submitting an application — especially when you need to compare authorities or screen applicants programmatically. Prefer this over generic regulatory lookup tools when the authority-specific rule logic and a machine-readable verdict are required.

## Known failure modes

- Unsupported or unrecognised authority name returns an error or non-OK status
- Missing required fields for a rule that depends on age or licence years may cause incomplete evaluation
- Authority name must be an exact supported string — fuzzy names may not resolve
- Response may be non-VERIFIED if the applicant does not meet the authority's criteria

## How this service works

One-authority deterministic England taxi-private-hire licensing preflight for a supported authority. Use for applicant, driver, vehicle, or operator blocker checks, missing-input identification, and the next evidence-gated action before submission or onboarding. This tool does not compare authorities. Deterministic England taxi/private-hire licensing decision with official-source evidence and per-rule freshness guards. Pay only when the blocker check or comparison is decision-relevant. Not licensing-authority approval or legal advice.

## Output

Returns a JSON object with a status field (e.g. 'OK') and a response_status field (e.g. 'VERIFIED') indicating whether the applicant meets the regulatory requirements of the specified England taxi/PHV licensing authority, based on evidence-linked rule checks for that authority.
