**Category:** Government & Public Data | **Website:** [naics.com/](https://naics.com/) | **Docs:** [parse.bot/marketplace/e43c72e2-bc4b-4a23-8c14-70c367cc205d/naics-com-api](https://parse.bot/marketplace/e43c72e2-bc4b-4a23-8c14-70c367cc205d/naics-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/naics/`
**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 all codes

Retrieve NAICS codes with their titles, hierarchy level, and sector information. Returns 2-digit sector codes, 4-digit industry group codes, and 6-digit national industry codes. Optionally filter by 2-digit sector prefix to narrow to one sector's hierarchy. Without a sector filter the full taxonomy is returned (1000+ codes).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `sector` | string | No | 2-digit sector code to filter by (e.g. '11', '23', '54'). If omitted, returns all sectors. |
| `version` | string | No | NAICS version year. |

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

### Get code details

Get detailed information about a specific NAICS code including its full industry description, top businesses by annual sales, cross-references to related NAICS codes, and index entries (activity descriptions classified under this code). Accepts any valid 6-digit NAICS code.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `code` | string | Yes | NAICS code (6-digit, e.g. '236115', '541511'). |
| `version` | string | No | NAICS version year. |

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

### Search codes

Search NAICS codes by keyword. Returns matching codes with titles, keyword excerpts, and SIC crosswalk availability. Results are server-ranked by relevance to the query term.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `query` | string | Yes | Search keyword (e.g. 'construction', 'software', 'restaurant'). |
| `version` | string | No | NAICS version year. |

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