Blackbird Labs

Blackbird Labs is a New York-based hospitality technology company building a payments and loyalty platform for restaurants and their guests. Its flagship product, Blackbird Pay, is a blockchain-powered payment network that charges restaurants roughly 2% per transaction and settles automatically at the table, while diners earn $FLY loyalty rewards by checking in and can redeem points across participating restaurants. Payments run over Flynet, a layer-three transaction protocol built on Coinbase's Base, and membership is represented by an NFC-tapped NFT. Founded by Resy and Eater co-founder Ben Leventhal, Blackbird is backed by Union Square Ventures, Spark Capital, Andreessen Horowitz, Coinbase Ventures, and Amex Ventures. Blackbird operates as a consumer mobile app and a merchant platform and does not currently publish a public developer API.

Blackbird Labs is profiled on the APIs.io network. Tagged areas include Company, Restaurant, Payments, Loyalty, and Blockchain.

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/.
