Practical working label — agree its meaning within your project
API Signal is a short, machine‑readable message attached to an endpoint response that conveys a specific condition such as service health, active feature flag, or version. It is designed for quick consumption by monitoring tools or other services without requiring full payload parsing.

When to use api signal
Use an API Signal when you need an instantly recognizable cue about a service’s state without extra request overhead.
A practical example of api signal
For example, a payment API adds a header `X‑Service‑Health: ok` to every response so downstream services can verify availability at a glance.
