# API Changelog

> Every wire-shape change between supported Nevermined API versions. The version identifier is the platform release MAJOR.MINOR.

Clients pin an API version per API key (editable in the dashboard) or per request
via the `Nevermined-Version` header; the platform reshapes requests and responses so
every supported pin keeps working. See the [versioning guide](/development-guide/api-versioning).

* **Floor (oldest supported version):** `1.0`
* **Live current version:** `GET /api/v1/meta/versions`

## 1.1

*Changes relative to `1.0`:*

* **Remove the legacy creditsConfig.proofRequired request alias — the canonical key is onchainMirror (clients below 1.1 keep the alias)** (`request`)
  * `POST /api/v1/protocol/plans`
  * `POST /api/v1/protocol/agents/plans`
* **Remove the deprecated always-null permission slots orderLimit/planCost/creditsPerOrder from responses (clients below 1.1 keep receiving them as null)** (`response`)
  * `GET /api/v1/x402/permissions`
  * `GET /api/v1/x402/permissions/:permissionHash`
