Cheddar Up
Cheddar Up is an all-in-one online platform that helps groups and communities collect payments and forms in one place. Purpose-built for PTAs/PTOs, booster clubs, youth sports teams, nonprofits, schools, clubs, HOAs, churches, and other volunteer-led organizations, it lets organizers collect dues, registrations, donations, event fees, fundraisers, and group gifts without any technical setup. It combines online payments (credit card, e-check, Apple Pay, Google Pay, and Link), custom forms, waivers, sign-ups, recurring payments, itemized storefronts, automated tracking and reporting, and multi-manager team administration. For technical users, Cheddar Up exposes an embeddable JavaScript SDK (a guest-facing Checkout component instantiated via CheddarUpWidgetFactory), API keys on the Team plan, and a native webhooks integration for syncing collection and payment events to external apps.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Cheddar Up the way a machine reads it — 3 machine-readable artifacts, 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 — Cheddar Up scores 34.4/100 (thin), with a separate agent-readiness read of 19/100 (agent aware). 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 Cheddar Up
Each block below is one kind of artifact we hold for Cheddar Up. 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.
Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 2
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.
