**Category:** E-commerce | **Website:** [muscleandstrength.com/](https://muscleandstrength.com/) | **Docs:** [parse.bot/marketplace/a2be0f01-d91b-44ae-ac3f-fdb73f7e9189/muscleandstrength-com-api](https://parse.bot/marketplace/a2be0f01-d91b-44ae-ac3f-fdb73f7e9189/muscleandstrength-com-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/muscleandstrength/`
**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

### Get product

Retrieve full product details by slug, including all size/flavor variants with individual SKUs, prices, availability, and GTIN codes. Size variants group flavors by package size with per-serving cost information.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `slug` | string | Yes | Product URL slug from search results (e.g. '100-whey-gold-standard', 'creatine-drive-black'). |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/muscleandstrength/get-product \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"slug":"<string>"}'
```

### Search products

Full-text search across the Muscle & Strength supplement store catalog. Returns paginated product listings with prices, stock status, and deal information. Results are ordered by relevance (most popular). Each result includes a slug usable with get_product for full variant details.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | integer | No | Page number for paginated results. Each page returns up to 20 products. |
| `query` | string | Yes | Search query for products (e.g. 'whey protein', 'creatine', 'pre-workout'). |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/muscleandstrength/search-products \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"page":"<integer>","query":"<string>"}'
```
