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/ups/`
**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

### Track shipment

Track a UPS shipment by its tracking number. Returns the current status, delivery information, milestones, and detailed shipment progress activities. Supports UPS tracking number formats (1Z, mail innovations, freight, etc). Each call tracks one shipment; for invalid numbers UPS returns input_format_invalid, for valid-format numbers not found in their system it returns input_not_found.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `locale` | string | No | Locale for the response language and formatting (e.g. en_US, nl_NL, de_DE). When omitted, defaults to en_US. |
| `tracking_number` | string | Yes | UPS tracking number (e.g. 1Z999AA10123456784). Supports standard 1Z format and other UPS tracking number formats. |
