Circuit Breaker
The Circuit Breaker is a stability pattern for distributed systems and API architectures that prevents cascading failure when a downstream service degrades. A breaker wraps a remote call and tracks failures against a threshold; when the threshold is exceeded the breaker "opens" and short-circuits subsequent calls (typically returning an error or fallback) without contacting the downstream service. After a cooldown the breaker enters a "half-open" probe state and either resets to "closed" on success or re-opens on failure. The pattern was popularized by Michael Nygard in *Release It!* and is now standard in resilient microservice and API gateway design.
Circuit Breaker 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.
Circuit Breaker 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.
