Paperplane
Paperplane is an AI sales-productivity tool (Y Combinator W23, backed by Bloomberg Beta) that automatically takes notes on sales calls and keeps a rep's CRM up to date. It connects to a team's calendar and to conversational intelligence and call-recording tools such as Gong and Chorus, transcribes and analyzes each call, then writes the results back to Salesforce — updating opportunity fields, notes, and action items so sales teams spend less time on manual CRM data entry and stay on top of their deals. The product is organized around opportunities, calls, and notes, with integrations for Google Calendar, Gong, Chorus, and Salesforce. Paperplane is a hosted SaaS application; as of this enrichment pass it exposes a product documentation site (GitBook, with an llms.txt index) but no public developer API, OpenAPI definition, or SDK.
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 Paperplane 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 — Paperplane scores 10.7/100 (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 Paperplane
Each block below is one kind of artifact we hold for Paperplane. 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.
