**APIs profiled:** 1

Headout is a global experiences marketplace that curates and sells tickets to tours, attractions, events, shows and activities across major cities worldwide. For developers, Headout operates a public Partner API (github.com/headout/api-docs) that lets affiliates and resellers browse the catalog (products, categories, collections and subcategories by city and language), pull live inventory and per-person/per-group pricing for a variant, and place bookings through a two-step create-then-capture flow. The API is versioned by URI path (v1 and v2 under /api/public/), authenticates with a Headout-Auth API key (pk_ production / tk_ sandbox), paginates with offset/limit, and returns a structured error envelope. A registrable seatmap iframe component is offered for seat selection. Headout is backed by 500 Global and Version One Ventures.
