**Category:** Developer Tools | **Website:** [duck.ai/](https://duck.ai/) | **Docs:** [parse.bot/marketplace/b468630c-21d3-4ab7-9d08-97df9085be00/duck-ai-api](https://parse.bot/marketplace/b468630c-21d3-4ab7-9d08-97df9085be00/duck-ai-api)

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

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/duck/`
**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

  -H "Content-Type: application/json" \
  -d '{}'
```

### Get status

Fetches the current Duck.ai service status, including primary and secondary status codes indicating service health. A status of '0' indicates the service is fully operational.
