**Category:** Automotive | **Website:** [autotrader.ca/](https://autotrader.ca/) | **Docs:** [parse.bot/marketplace/17f38610-10ed-4f84-a76c-34ccc296ba3a/autotrader-ca-api](https://parse.bot/marketplace/17f38610-10ed-4f84-a76c-34ccc296ba3a/autotrader-ca-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/autotrader-canada/`
**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.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

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

## Endpoints

### Get listing details

Retrieve full details for a specific vehicle listing on AutoTrader.ca. Requires the listing URL obtained from search_listings results. Returns complete specifications, seller contact details, pricing breakdown, description, and all listing images. Expired or removed listings return input_not_found.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `url` | string | Yes | The full AutoTrader.ca listing URL from search_listings results[*].url |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/autotrader-canada/get-listing-details \

  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"url":"<string>"}'
```

### Search listings

Search vehicle listings on AutoTrader.ca. Filters by make, location, and sort order. Returns paginated results with total count. Each listing includes summary vehicle info (make, model, year, price, mileage, condition, location, transmission, fuel type) plus a URL for drilling into full details via get_listing_details. Pagination is manual via offset/limit.

**Estimated cost:** Metered

| Field | Type | Required | Description |

| `limit` | integer | No | Number of results per page |
| `location` | string | No | Location for the search in City, Province format (e.g. Toronto, ON; Vancouver, BC) |
| `make` | string | No | Filter by vehicle make (e.g. Honda, Toyota, Ford, Mercedes-Benz). Omitting returns all makes. |
| `offset` | integer | No | Result offset for pagination (0-based item index) |
