-      ## How Processor Plugins Extend the API
+      Retrieve the live OpenAPI specification for this instance. Unlike the static spec, this endpoint
-
+      returns the fully merged spec including schemas for any processor plugins installed on this instance.
-      changedetection.io uses a **processor plugin** system to handle different types of change detection.
-      Each processor lives in `changedetectionio/processors/<name>/` and may include an `api.yaml` file
-      that extends the core Watch schema with processor-specific configuration fields.
-
-      ### How it works
-
-      At startup, changedetection.io scans all installed processors for an `api.yaml` file. Any schemas
-      and code samples defined there are deep-merged into the live API specification, making the
-      processor's configuration fields valid on all watch create and update requests.
-
-      The live, fully-merged spec is always available at `/api/v1/full-spec` — use that URL with
-      Swagger UI or Redoc to see the complete schema for your specific installation.
-
-      ---
-
-      ### Writing a processor `api.yaml`
-
-      Place an `api.yaml` in the processor plugin's own directory, alongside its `__init__.py`
-      (e.g. `changedetectionio/processors/my_processor/api.yaml`). The schema name **must** follow the
-      convention `processor_config_<processor_name>` (e.g. `processor_config_restock_diff`). That same
-      key is used as the JSON field name when creating or updating a watch.
-
-      A minimal `api.yaml` for a hypothetical `my_processor`:
-
-      ```yaml
-      components:
-        schemas:
-          processor_config_my_processor:
-            type: object
-            description: Configuration for my_processor
-            properties:
-              some_option:
-                type: boolean
-                default: true
-                description: Enable some behaviour
-
-      paths:
-        /watch:
-          post:
-            x-code-samples:
-              - lang: curl
-                label: my_processor example
-                source: |
-                  curl -X POST "http://localhost:5000/api/v1/watch" \
-                    -H "x-api-key: YOUR_API_KEY" \
-                    -H "Content-Type: application/json" \
-                    -d '{
-                      "url": "https://example.com",
-                      "processor": "my_processor",
-                      "processor_config_my_processor": { "some_option": true }
-                    }'
-      ```
-
-      The `paths` section in `api.yaml` is used only for injecting additional `x-code-samples` into
-      existing endpoints — you cannot define new routes via plugin.
-
-      ---
-
-      ### Built-in plugin: `restock_diff`
-
-      The `restock_diff` processor is always shipped with changedetection.io. It monitors product
-      availability and price changes using structured data (JSON-LD / schema.org microdata) and
-      text heuristics. It is activated by setting `"processor": "restock_diff"` on a watch.
-
-      It adds the `processor_config_restock_diff` block to the Watch schema with these fields:
-
-      | Field | Type | Default | Description |
-      |---|---|---|---|
-      | `in_stock_processing` | string | `in_stock_only` | `in_stock_only` — only alert Out-of-Stock→In-Stock · `all_changes` — alert any availability change · `off` — disable stock tracking |
-      | `follow_price_changes` | boolean | `true` | Monitor and alert on price changes |
-      | `price_change_min` | number\|null | — | Alert when price drops **below** this value |
-      | `price_change_max` | number\|null | — | Alert when price rises **above** this value |
-      | `price_change_threshold_percent` | number\|null | — | Minimum % change since the original price to trigger an alert |
-
-      #### CREATE — Add a restock/price monitor
-
-      ```bash
-      curl -X POST "http://localhost:5000/api/v1/watch" \
-        -H "x-api-key: YOUR_API_KEY" \
-        -H "Content-Type: application/json" \
-        -d '{
-          "url": "https://example.com/product/widget",
-          "processor": "restock_diff",
-          "processor_config_restock_diff": {
-            "in_stock_processing": "in_stock_only",
-            "follow_price_changes": true,
-            "price_change_threshold_percent": 5
-          }
-        }'
-      ```
-
-      #### READ — Retrieve the monitor
-
-      The response JSON includes `processor_config_restock_diff` alongside all standard watch fields:
-
-      ```bash
-      curl -X GET "http://localhost:5000/api/v1/watch/cc0cfffa-f449-477b-83ea-0caafd1dc091" \
-        -H "x-api-key: YOUR_API_KEY"
-      ```
-

-          "follow_price_changes": true,
-          "price_change_threshold_percent": 5,
-          "price_change_min": null,
-          "price_change_max": null
-        }
-      }
-      ```
-
-      #### UPDATE — Change thresholds without recreating the monitor
-
-      Only fields included in the request body are updated; omitted fields are left unchanged.
-
-      ```bash
-      curl -X PUT "http://localhost:5000/api/v1/watch/cc0cfffa-f449-477b-83ea-0caafd1dc091" \

-            "price_change_max": 500.00
-          }
-        }'
-      ```
-
-      #### DELETE — Remove the monitor
-
-      ```bash
-      curl -X DELETE "http://localhost:5000/api/v1/watch/cc0cfffa-f449-477b-83ea-0caafd1dc091" \
