Syntropy
Syntropy is an autonomous, agentic coding application built for complex, long-horizon software engineering tasks. A developer describes a feature in natural language and Syntropy plans, writes, and tests the implementation, returning a production-ready pull request without the developer having to manage a terminal or an IDE agent session by hand. The product emphasizes large-context handling for heavy, real-world codebases ("no context ceiling, no truncation"), supports custom Model Context Protocol (MCP) integrations so it can pull in a team's own tools, and joins Slack to post updates as tasks complete. Syntropy is a Y Combinator (Winter 2026) company based in San Francisco, founded by Saahil Sundaresan and Andrew Kuik. As of this profile it ships as a hosted end-user coding product and does not publish a public developer API, SDK, or API documentation.
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 Syntropy 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 — Syntropy scores 9.4/100 (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.

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