**Category:** Automotive | **Website:** [www.mbusa.com/en/home](https://www.mbusa.com/en/home) | **Docs:** [parse.bot/marketplace/d5fca660-8e66-4eda-b8c2-8e1922e37edd/mbusa-com-api](https://parse.bot/marketplace/d5fca660-8e66-4eda-b8c2-8e1922e37edd/mbusa-com-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/mbusa/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Search inventory

Search new Mercedes-Benz vehicle inventory by US zip code. Returns paginated listings with full specs, pricing, dealer info, and available filter facets for refinement. Sorted by distance from zip by default. Each vehicle includes VIN, MSRP, engine, colors, features, dealer location with distance, and monthly payment estimates. The available_filters object enumerates every filterable dimension with counts, enabling progressive narrowing.

**Estimated cost:** Metered
