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/smiles/`
**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

### Search flights

Search for available flights using Smiles miles. Returns flight options with pricing across multiple fare types (Smiles, Clube Smiles, Smiles+Money, Smiles+Money Club). Supports both one-way and round-trip searches. Results include departure/arrival times, duration, stops, airline, seat availability, and per-fare pricing (miles, money, tax). One-way returns only SEGMENT_1 flights; round-trip returns both SEGMENT_1 (outbound) and SEGMENT_2 (return) flights.

**Estimated cost:** Metered
