Blackbird

Blackbird Labs is the membership network for restaurant lovers, founded by Eater and Resy co-founder Ben Leventhal. Its consumer app lets diners earn status, perks, and points at world-class restaurants and pay their check in FLY, Blackbird's loyalty token. Blackbird's developer platform is the Flynet API — read access to the dining network (restaurants, locations, check-ins, member identity, and memberships) plus FLY Payment Intents modeled on Stripe — backed by an OpenAPI spec, first-party TypeScript SDKs (@flynetdev/core and @flynetdev/react), two MCP servers, a published agent skill, and llms.txt. Flynet is a layer-3 network built on Coinbase's Base chain. Backed by a16z, dcvc, and multicoin-capital.

Blackbird publishes 10 APIs on the APIs.io network, including App API, Challenges API, Check-ins API, and 7 more. Tagged areas include Company, Restaurants, Loyalty, Payments, and Dining.

Blackbird’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 19 more developer resources.
