- [Overview](https://developer.hellgate.io/products/link/overview.md): Link is a protocol-abstraction runtime: define an API contract once, bind it to any provider, and switch what's behind it without changing the caller.
- [Plans & Access](https://developer.hellgate.io/products/link/plans-and-access.md): Link editions — Bundled and Standalone — environment tiers, and how to obtain an instance.
- [Authentication](https://developer.hellgate.io/products/link/authentication.md): Authenticate to your Link instance with a bearer JWT, and scope each token to the operations it needs.
- [Quickstart](https://developer.hellgate.io/products/link/quickstart.md): Import a protocol, register a backend, and invoke your first action end to end.
- [Protocols](https://developer.hellgate.io/products/link/concepts/protocols.md): A protocol is a versioned, schema-validated API contract: the actions callers invoke and the shape of each request and response.
- [Protocol schema](https://developer.hellgate.io/products/link/concepts/protocol-schema.md): The Link protocol meta-schema — author your own protocols on a Standalone instance.
- [Backends](https://developer.hellgate.io/products/link/concepts/backends.md): A backend binds a protocol to a real provider: its host, credentials, authentication, and the declarative mapping rules that translate the contract into the provider's wire format.
- [Invocation](https://developer.hellgate.io/products/link/concepts/invocation.md): Calling a protocol action: how Link selects a backend, runs the mapping, and returns a protocol-shaped result or error.

- [Invoke protocol action](https://developer.hellgate.io/products/link/api-reference/invoke/invoke-protocol-action.md): Executes a protocol action against a backend. The HTTP method must match the action's declared method. The request and response bodies are **defined by the invoked protocol**, not by this API — retrieve the exact shapes from the protocol's generated OpenAPI (`GET /api/admin/protocols/{id}/openapi`).
- [List protocols](https://developer.hellgate.io/products/link/api-reference/protocols/list-protocols.md): Returns a paginated list of registered protocols.
