VigLink (Sovrn Commerce)

VigLink pioneered automatic affiliate link monetization for publishers, turning ordinary product links into revenue-generating affiliate links across a network of tens of thousands of merchants. Founded in 2009 and backed by investors including Uncork Capital, VigLink was acquired by Sovrn in early 2018 and now operates as Sovrn Commerce. The product's public APIs still run on VigLink infrastructure (api.viglink.com, rest.viglink.com, viglink.io) and cover link monetization checks, real-time bid checks, campaigns, real-time revenue reporting, merchant summaries, product recommendations, promo codes, and price comparisons, documented on the Sovrn Developer Center alongside a hosted Commerce MCP server for AI agents.

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 VigLink (Sovrn Commerce) the way a machine reads it — 14 machine-readable artifacts across 8 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 — VigLink (Sovrn Commerce) scores 50.3/100 (developing), with a separate agent-readiness read of 76/100 (agent native). 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 VigLink (Sovrn Commerce)

Each block below is one kind of artifact we hold for VigLink (Sovrn Commerce). 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.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

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.

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.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
