+### Compling a Rego policy (and query) into data filters
+
+```http
+POST /v1/compile/{path:.+}
+Content-Type: application/json
+```
+
+Where the `{path}` is the slash delimited filter rule to be compiled.
+E.g., to compile the `data.filters.include` rule, query `/v1/compile/filters/include`
+
+
+#### Request Headers
+
+| Name | Required | Accepted Values | Description |
+| --- | --- | --- | --- |
+| Content-Type | No | `application/json` | Indicates the request body is either a JSON encoded document. |
+| Content-Encoding | No | gzip | Indicates the request body is a compressed gzip object. |
+| Accept | Yes | See [below](#accept-header--controlling-the-target-response-format) | See [below](#accept-header--controlling-the-target-response-format) |
+
+
+#### Accept Header – Controlling the Target Response Format
+
+The same request can generate filters that are representable in many different ways, such as raw SQL `WHERE` clauses or Universal Conditions AST (UCAST).
+
+OPA uses the `Accept` header to denote the target response format.
+
+| Value | Response Schema | Description |
+| --- | --- | -- |
+| Multitarget: `application/vnd.opa.multitarget+json` | `result.{ucast,sqlserver,mysql,postgresql,sqlite}` | The partially evaluated result of the query in each target dialect. Use the `options.targetDialects` field in the request body to control targets. |
+| UCAST: `application/vnd.opa.ucast.all+json`, `application/vnd.opa.ucast.minimal+json`, `application/vnd.opa.ucast.linq+json`, `application/vnd.opa.ucast.prisma+json` | `result.query`| UCAST JSON object describing the conditions under which the query is true. |
+| SQL: `application/vnd.opa.sql.sqlserver+json`, `application/vnd.opa.sql.mysql+json`, `application/vnd.opa.sql.postgresql+json`, `application/vnd.opa.sql.sqlite+json` | `result.query`| String representing the SQL equivalent of the conditions under which the query is true. |
+
+
+#### Request Body
+
+| Field | Type | Required | Description |
+| --- | --- | --- | --- |
+| `input` | `any` | No | The input document to use during partial evaluation and during mask rule evaluation (default: undefined). |
+| `options` | `object[string, any]` | No | Additional options to use during partial evaluation |
+| `options.disableInlining` | `array[string]` | No. Default: undefined | A list of rule references. |
+| `options.maskRule` | `string` | No | The rule to evaluate for generating column masks. Overrides any `mask_rule` annotations defined in the policy. |
+| `options.targetDialects` | `array[string]`, one of `ucast+all`, `ucast+minimal`, `ucast+prisma`, `ucast+linq`, `sql+sqlserver`, `sql+mysql`, `sql+postgresql` | Yes, if using `multitarget`. **Ignored for all other targets** | The output targets for partial evaluation. Different targets will have different constraints. Use [`Accept` header](#accept-header--controlling-the-target-response-format) to request a single compilation target.  |
+| `options.targetSQLTableMappings` | `object[string, object[string, string]]` | No | A mapping between tables and columns. See the [example](#using-table-and-column-remappings) for the schema. |
+| `unknowns` | `array[string]` | No | The terms to treat as unknown during partial evaluation (default: `["input"]`]). |
+
+
+#### Example Request
+
+With OPA running with this policy, we'll compile the query `data.filters.include` into SQL filters:
+
+```rego
+package filters
+
+# METADATA
+# scope: document
+# custom:
+#   unknowns: [input.fruits]
+include if input.fruits.name == input.favorite
+
+include if {
+	input.fruits.name == "apple"
+	not input.favorite
+}
+```
+
+```http
+POST /v1/compile/filters/include HTTP/1.1
+Content-Type: application/json
+Accept: application/vnd.opa.sql.postgresql+json
+```
+
+```json
+{
+  "input": {
+    "favorite": "pineapple"
+  }
+}
+```
+
+
+#### Example Response
+
+```http
+HTTP/1.1 200 OK
+Content-Type: application/vnd.opa.sql.postgresql+json
+```
+
+```json
+{
+  "result": {
+    "query": "WHERE fruits.name = E'pineapple'"
+  }
+}
+```
+
+
+#### Unconditional Results from Filters Generation
+
+An absent `query` in the `result` indicates **unconditional deny**:
+
+```json
+{
+  "result": {}
+}
+```
+
+An empty string `query` indicates **unconditional include**:
+
+```json
+{
+  "result": {
+    "query": ""
+  }
+}
+```
+
