Schema Free
Schema Free (schemaless) databases and APIs allow data to be stored and retrieved without a predefined fixed schema. Rather than enforcing structure at the database level, schema-free systems delegate schema management to the application layer. This enables rapid prototyping, flexible document storage, and agile development workflows. Key schema-free technologies include MongoDB (document store), Redis (key-value store), Apache Cassandra (wide-column store), Amazon DynamoDB (managed NoSQL), Elasticsearch (search/document store), and Apache CouchDB. While called "schemaless," these systems typically have implicit application-level schemas that must be managed carefully.
Schema Free is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Schema Free is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
