Blockdaemon

Blockdaemon is an institutional blockchain infrastructure company founded in 2017 by Konstantin Richter. It runs production node infrastructure, staking, indexed data, DeFi, custody, and tokenization services across 80+ blockchain protocols for 400+ institutional clients including Goldman Sachs, Microsoft, JP Morgan, and Citi Ventures. The Blockdaemon API Suite bundles a unified Data API (Ubiquity), JSON-RPC nodes, a Staking API, Staking Reporting API, DeFi aggregator (expand.network), Token Pricing API, Chain Watch event streaming, and a Management API. Wallet products include Builder Vault TSM (MPC for builders), Institutional Vault (self-hosted MPC custody with Automated Approver Service), and Wallet Transact. Earn Stack covers a no-code embeddable Earn Widget plus liquid staking and restaking. Compute Unit metering, triple-mode authentication, an MCP server, and SOC 2 Type II / ISO 27001 certifications round out the platform. $110B+ in digital assets secured and $10B+ staked on Blockdaemon validators.

agent aware

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Blockdaemon the way a machine reads it — 50 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 — Blockdaemon scores 53.9/100 (developing), with a separate agent-readiness read of 31/100 (agent aware). 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 Blockdaemon

Each block below is one kind of artifact we hold for Blockdaemon. 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.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON Schema 3

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 2

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.
