APIs.json is one of 15 APIs that [Agent Readiness](https://apis.io/providers/agent-readiness/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Discovery, Agent Readiness, and Standards. The published artifact set on APIs.io includes API documentation and a GitHub repository.

The APIs.json format describes a provider's API portfolio in one machine-readable document. Publishing `/apis.json` (or `/apis.yml`) at the site root is the agent-readiness equivalent of a site identity card — it tells an agent who the operator is and what surfaces are on offer.
