# Diminished Value Report

> How much value an accident took even after a quality repair.

**Price:** $5.99 per report. Runs inside Claude or ChatGPT (MCP), or as a shareable hosted web report. Pay per report, no subscription.

Diminished value claim baseline: pre-loss value via ML + 17c-modified formula with severity multiplier + mileage penalty. Returns a comparable-based DV figure, NOT a state-specific 17c claim — for court-defensible numbers in GA/MS/etc., supplement with a certified DV appraiser. Use when the user is filing or evaluating a diminished value claim after an accident.

## Inputs

### Required
- **vin** (e.g. `5YJ3E1EA8KF000000`): 17-character vehicle identification number.
- **mileage** (e.g. `31000`): Current vehicle mileage.
- **accident_date** (e.g. `2026-02-10`): Date of the accident in ISO format (YYYY-MM-DD).
- **damage_severity** (e.g. `moderate`): Damage severity: "minor", "moderate", or "severe". Drives the severity multiplier in the DV formula.

### Recommended
- **repair_cost_usd** (e.g. `4200`): Documented repair cost (separate claim from DV but useful context).
- **state** (e.g. `GA`): US state abbreviation (e.g. GA, MS, TX). Used to flag state-specific 17c formula availability.

### Optional
- **zip** (e.g. `30309`): Vehicle owner's ZIP code. Improves regional context.
- **appraiser_name** (e.g. `Jane Smith, ASA`): Appraiser or preparer name for the certification block. Defaults from the appraisal profile in account settings on appraisal-flavored runs; a value typed here always wins.
- **appraiser_license** (e.g. `UT Lic. 12345`): License or credential shown with the preparer name. Defaults from the appraisal profile in account settings.
- **client_name** (e.g. `Acme Insurance`): Client the appraisal is prepared for (renders in the certification block).
- **file_number** (e.g. `CLM-2026-0417`): Claim / file / stock reference number for the certification block. Leave blank to auto-assign the next number in your account's own series (e.g. ACME-2026-0007; set the prefix in account settings) whenever appraiser fields are used.
- **exclude_vins** (e.g. ``): Comparables to EXCLUDE (comma or newline separated VINs). They are dropped from every pool before valuation and listed as considered-and-rejected.

## Data semantics

Every price is a **listed (asking) price**, not a transacted sale price. "Recently off-market" comps show a vehicle's last list price (a sold proxy). The ML "MarketCheck Price" predicts an optimal listing price, not a sale price.
