Dapper Labs
Dapper Labs is the blockchain company behind the Flow network and a portfolio of consumer NFT experiences including NBA Top Shot, NFL All Day, Disney Pinnacle, and LaLiga Golazos. Its primary public developer surface is the Flow Access API — a public, unauthenticated blockchain node API available over REST (rest-mainnet.onflow.org), gRPC, and WebSocket event streaming — used to read on-chain data (blocks, transactions, accounts, collections, events), execute read-only Cadence scripts, and submit signed Cadence transactions. Flow and its client tooling (FCL, the Flow CLI, Go/JS SDKs) are maintained under the onflow GitHub organization. This profile began as a VC-portfolio stub and has been enriched by the API Evangelist pipeline from Dapper/Flow's real developer artifacts.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Dapper Labs the way a machine reads it — 14 machine-readable artifacts across 11 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Dapper Labs scores 40.3/100 (thin), with a separate agent-readiness read of 46/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Dapper Labs
Each block below is one kind of artifact we hold for Dapper Labs. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 11
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
