**Category:** Maps & Geospatial | **Website:** [empresas.correios.com.br/](https://empresas.correios.com.br/) | **Docs:** [parse.bot/marketplace/453dd6d6-a632-48ce-81de-32dfdae51def/empresas-correios-com-br-api](https://parse.bot/marketplace/453dd6d6-a632-48ce-81de-32dfdae51def/empresas-correios-com-br-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/empresas-correios/`
**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

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
