> Browse and filter upcoming events at London's Barbican Centre by category and date range to find performances, exhibitions, and cultural events that match your interests. Quickly discover what's happening at the venue without having to navigate their website directly.

**Category:** Entertainment | **Website:** [www.barbican.org.uk/](https://www.barbican.org.uk/) | **Docs:** [parse.bot/marketplace/e64d111d-fe94-4d43-bc51-5ba5645387ed/barbican-org-uk-api](https://parse.bot/marketplace/e64d111d-fe94-4d43-bc51-5ba5645387ed/barbican-org-uk-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/barbican/`
**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.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents
