# inferParameterSources

**Kind:** Function

**Source:** [`atloria-monorepo/libs/parser-core/src/openapi/param-source-inference.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/openapi/param-source-inference.ts#L159)

Walk every operation and attach a `x-atloria-param-source` to each path parameter whose
values a sibling collection can supply.

Conservative by construction: a binding is emitted only when the collection operation
exists, returns a list of objects, and that object carries a usable identifier. Anything
ambiguous is left alone — a text box is a fine outcome, a wrong dropdown is not.

## Signature

```ts
function inferParameterSources(spec: OpenApiLike): number
```

## Parameters

| Name | Type |
|---|---|
| `spec` | `OpenApiLike` |

**Returns:** `number`
