Tools

Free: taxi_phv_info, list_supported_authorities, licensing_source_status.

x402 paid: taxi_licence_preflight ($0.02 USDC), compare_licensing_requirements ($0.05 USDC).

Recommended workflow

1. Call taxi_phv_info for pricing and service metadata.
2. Call list_supported_authorities before paying for a decision.
3. Use licensing_source_status when evidence freshness matters.
4. Call taxi_licence_preflight for one authority or compare_licensing_requirements for several.

Example: single-authority preflight

{
  "payload": {
    "authority": "City of Bradford Metropolitan District Council",
    "age": 30,
    "driving_licence_years": 4,
    "has_pass_plus_certificate": true
  }
}

Example: compare authorities

{
  "payload": {
    "authorities": [
      "City of Bradford Metropolitan District Council",
      "Cambridge City Council"
    ],
    "applicant": {
      "age": 30,
      "driving_licence_years": 4,
      "has_pass_plus_certificate": true
    }
  }
}

Evidence safety

Decisions are verified only when declared official-source dependencies have usable current evidence. Source failures and conflicts fail closed per affected rule.

Preflight information only; not licensing-authority approval or legal advice.

Why pay?

• Pay $0.02 for a deterministic applicant or fleet blocker check for one authority, including missing facts and the next evidence-gated action before submission or onboarding.
• Pay $0.05 for a cross-authority trade-off comparison before choosing where to license.

How x402 works

1. Call the paid tool to receive an x402 challenge.
2. Sign the authorization buyer-side; never send a private key or seed phrase.
3. Retry the same call with payment metadata.
4. Receive a verified decision or confirmation-required result after payment verification and evidence checks.
