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, Restaurant, Loyalty, Payments, and Dining.

Blackbird’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/blackbird: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
