Hourglass
Hourglass is a DeFi protocol and time-bound token (TBT) infrastructure that invented a primitive for tokenizing staked, locked, or time-committed on-chain assets, letting holders trade their place in a lock-up queue for early liquidity. Its products include an RFQ marketplace built on OpenSea's Seaport for trading time-bound tokens, non-custodial on-chain vaults (including the Pre-iUSDT stable vault and the sunset Hourglass Boost product), and institutional-grade yield infrastructure that bridges on-chain DeFi capital with traditional capital markets. TBTs are semi-fungible ERC-1155 tokens issued by Hourglass custodian smart contracts on Ethereum. Launch partners included Lido, Frax, and Convex. Founded in 2022 and backed by a $4.2M seed round led by Electric Capital, with Coinbase Ventures, Circle Ventures, and others participating.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Hourglass the way a machine reads it — 2 machine-readable artifacts, 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 — Hourglass scores 13.6/100 (minimal), with a separate agent-readiness read of 4/100 (human only). 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 Hourglass
Each block below is one kind of artifact we hold for Hourglass. 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.
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.
