# Turn a sentence into a filter

`POST https://your-suite.grid82.app/your-app/v1/tables/{tableId}/filters/suggest`

Return the complete filter to apply, given the table's fields, visible example values, and existing filter; return a plain-word refusal when the sentence is not about narrowing rows.

> **Note: Generic contract**
>
> Your own version of this operation, with your tables and the fields you can read, is in
> your app's document: `https://{suite}.grid82.app/{app}/v1/openapi.json`, behind your credential.

This is a small model call, not the assistant, and costs credits.

Requires the `records:read` scope. Operation `filters.suggest`. MCP tool `filters_suggest`. CLI: `grid82 filters suggest` (`npx grid82`).
