**Category:** Government & Public Data | **Website:** [masothue.com/](https://masothue.com/) | **Docs:** [parse.bot/marketplace/bd558b3b-48e5-480d-a86e-6f85f482a21f/masothue-com-api](https://parse.bot/marketplace/bd558b3b-48e5-480d-a86e-6f85f482a21f/masothue-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/masothue/`
**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 company detail

Retrieve full registration details for a single Vietnamese company. Accepts either a detail_path (from search_company results, most reliable) or a tax_code (triggers an intermediate search to locate the detail page). Returns official name, tax address, status, representative, industry, and other registration fields.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `detail_path` | string | No | Detail path from search_company results (e.g. /0314539064-cong-ty-tnhh-vinamilk-tan-son). Navigates directly to company page. |
| `tax_code` | string | No | Company tax code with leading zeros preserved (e.g. 0314539064). Used to search and find the company detail page. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/masothue/get-company-detail \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"detail_path":"<string>","tax_code":"<string>"}'
```

### Search company

Full-text search over Vietnamese companies by name, tax code, ID number, or representative name. Returns up to 20 companies per page. Pagination via integer page counter. The search type narrows the interpretation of the query string — 'auto' lets the server decide.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | integer | No | Page number for pagination. |
| `query` | string | Yes | Search query - company name, tax code, ID number, or representative name. |
| `type` | string | No | Search type filter. |

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