Sardine
Sardine is a San Francisco-based fraud prevention, AML compliance, and risk management platform for fintechs, banks, marketplaces, and crypto VASPs. It unifies onboarding (KYC, KYB, document and bank verification), device intelligence and behavioral biometrics, payment and card fraud scoring, AML transaction monitoring, sanctions screening, and case management into a single risk operating system. Sardine's "agentic" layer applies atomic agents (OSINT, data analysis, transaction monitoring, business due diligence, sanctions screening) to compress investigation time from days to minutes, while Sonar provides cross-industry fraud intelligence across the consortium. The platform serves 400+ enterprise customers including FIS, GoDaddy, Intuit, Nubank, Novo, and bunq, has screened $1.3T+ in payments, and profiled 5.4B+ devices. Sardine has raised ~$170M from Andreessen Horowitz, Visa, Experian, Google Ventures, FIS, and others. Public docs cover the risk landscape and integration overview; full API reference, SDKs, and sandbox access are gated and require a Sardine account.
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 Sardine the way a machine reads it — 32 machine-readable artifacts across 6 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 — Sardine scores 22.1/100 (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 Sardine
Each block below is one kind of artifact we hold for Sardine. 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 6
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.

Security Posture 3
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.
