**Category:** Sports | **Website:** [calendar.fide.com/calendar.php](https://calendar.fide.com/calendar.php) | **Docs:** [parse.bot/marketplace/e47b3f6e-1237-4ad2-be98-b299ba1059c7/calendar-fide-com-api](https://parse.bot/marketplace/e47b3f6e-1237-4ad2-be98-b299ba1059c7/calendar-fide-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/calendar-fide/`
**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

Returns comprehensive information including event type (online/in-person), time control, tournament system (Swiss/Round-Robin), prize fund, country, city, venue, and related events when available. Not all fields are present for every tournament — only fields the organizer has registered with FIDE are returned.

**Estimated cost:** Metered
