Rallybio
Rallybio Corporation (NASDAQ RLYB) is a clinical-stage biotechnology company headquartered in New Haven, Connecticut, founded in 2018, developing and commercializing life-transforming therapies for patients with severe and rare diseases. Its pipeline spans maternal-fetal health, complement dysregulation, hematology, and metabolic disorders, led by RLYB116, a differentiated complement component 5 (C5) inhibitor, and RLYB332, a long-acting matriptase-2 (MTP-2) antibody for iron-overload disorders. The company was surfaced as a portfolio company of Canaan Partners and added to the API Evangelist network. As a pharmaceutical company it publishes no public developer API, SDK, or machine-readable API surface; this profile captures corporate identity only.
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.
Rallybio is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Rallybio scores 13.0/100 (minimal), with a separate agent-readiness read of 0/100 (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.

The organization behind the API
Rallybio is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
