Erasca
Erasca is a clinical-stage precision oncology company (NASDAQ: ERAS) headquartered in San Diego, California, whose name is its mission: to erase cancer. The company is singularly focused on discovering, developing, and commercializing therapies for RAS- and MAPK pathway-driven cancers. RAS is the most frequently mutated oncogene and the MAPK pathway one of the most frequently altered signaling pathways in cancer, together accounting for roughly five million newly diagnosed patients globally each year. Erasca pursues three complementary therapeutic strategies intended to comprehensively shut down the RAS/MAPK pathway by targeting multiple nodes and cooperative mechanisms in parallel. This API Evangelist profile was surfaced as an a16z portfolio-linked lead; as a therapeutics company Erasca publishes a corporate and investor web presence rather than a developer API surface, so this record captures verified company identity, legal, and domain-security signals only.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Erasca the way a machine reads it — 1 machine-readable artifact, 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 — Erasca scores 15.0/100 (emerging), 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.

How we profile Erasca
Each block below is one kind of artifact we hold for Erasca. 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 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.
