10 tools

• decode_plate

  When a UK plate of this format could have been issued, from the plate alone (format, age identifier, and the window as first and last month). Offline: it does not look the car up; use free_check for that. No account needed.

• free_check

  The site's free check: identity, tax and MOT status, latest MOT test, its defects and recorded mileage, the existing since-previous-test summary and mileage-unverified flag. Includes presentation, up to three questions from these free facts, a verdict image, locked…

• resolve_vehicle

  Resolve a typed plate, car photo data URL or supported advert URL to a plate only. No account or spend. If uncertain, ask the user to confirm; if unavailable, ask for the typed plate. Then use free_check.

• compare_vehicles

  Compare the site's free projections for exactly two plates: identity, status and latest MOT test. Duplicate plates use one lookup. Includes questions from free facts, comparison image and report links. No prediction-based ranking; next-MOT estimates and likely repairs…

• sample_report

  The detailed report and viewing advice for one public sample car (CX52HHM, a 2002 Land Rover Defender), to show what a detailed report contains. Use when the user asks what RegTail's detailed report looks like. No account needed. It is always the same sample car, never…

• full_report

  The detailed report of a car the user has unlocked on their RegTail account: verdict and top risks, every MOT test with defects and advisories, mileage analysis, recurring advisories, other sections, the viewing checklist, what was not checked, and guidance for…

• unlock_report

  Spends one of the user's RegTail credits to unlock the detailed report for this plate for 30 days, then returns the detailed report (as full_report does). Ask the user first, every time, and call this only after they agree; never unlock on your own initiative or to…

• viewing_advice

  Advice for viewing an unlocked car in person: a summary, priorities to check (each with why and the report records behind it) and known weak spots of the model. Needs the user's RegTail account linked and the plate unlocked; never spends.

• credits_balance

  How many credits the user's RegTail account holds, and pricing_url, a page explaining how credits work. Needs the user's RegTail account linked.

• my_reports

  The cars the user has unlocked (with when each unlock ends) and their recent checks, so a conversation can pick up a car checked earlier. Needs the user's RegTail account linked.
