Pricing

For buyers

• Buying tickets — 0. No platform charge to buy. A ticket costs its face value plus the booking fee the organizer set for that ticket type — shown all-in before checkout, and the number every API returns. No card surcharge is added at payment.

For organizers

• Selling tickets — organizer commission — see below. A commission on gross ticket revenue, agreed per organizer account and taken from each sale at settlement — nothing up front.

For agents and developers

• Agent and developer access — discovery — 0 per request. The catalogue, UCP catalog and checkout endpoints, the discovery documents, the MCP connectors and OAuth are free, with no key to request.
• Agent access — paid resources — see below. Where this deployment prices a machine-only resource (for example a markdown rendition requested with Accept: text/markdown by an unverified agent), the price and the rails (x402, MPP) are published per operation as x-payment-info in /openapi.json, and the 402 challenge is authoritative. Unpriced routes never challenge.

Machine-readable

This page carries a schema.org OfferCatalog in JSON-LD, and Accept: text/markdown returns it as markdown. Per-event ticket prices are Offers on each event page and in the UCP catalogue; the agent tariff, where one is configured, is in /openapi.json.
