A dry run of the embed job's own sweep priced by the catalog rule, at the platform key every call runs on. No writes, no charges. Surface the numbers to the user before update_playtable_field sets payload.semantic_index. Contract: - MCP tool `estimate_semantic_index`, registry package `mcp.playtables/playtable_fields`, mount `playtables.columns`. - Operation `action`, response envelope `action`. - Flags: read only. ## OpenAPI ````yaml /api-reference/playtables/openapi.yaml post /api/playtable-fields/{sid}/estimate-semantic-index openapi: 3.0.3 info: title: 'GetSales public contract: gs.service.playtables' description: >- The data platform and the outreach engine: tables of people and companies, their enrichment columns, cells and runs, the data sources that feed them, sender profiles, the stoplist, the activity feed, the credit ledger, and the multichannel workflows with their per-person journeys and tasks. GENERATED. This document is projected from the Zod MCP tool registry in `product/mcp/gs.mcp` (one tool per public endpoint, 1:1). Do not edit it by hand; edit the tool definition and regenerate with `pnpm openapi:public`. Surface: the public `/api` contract of `gs.service.playtables`, 142 operations. This is the only OpenAPI document the platform publishes. Internal (`/internal`) and health endpoints are deliberately absent: they are not part of any contract, they can change without notice, and the service source is their only description. Conventions: - Auth is a bearer JWT, optionally narrowed by the `Team-SID` header. - Every success body is an MCP envelope: `success: true` plus one typed `operation` shape (`search`, `get`, `create`, `update`, `delete`, `metrics`, `group_by`, `action`), and a `meta` block with `trace_id` for support. - Every failure is the same `McpError` envelope with a code from a fixed 16-code taxonomy, so a client maps errors once. - Lists page with `page_size` (0 to 500, default 50) plus an opaque forward `cursor`; `page_size: 0` returns counts only. - On `GET` and `DELETE`, object-valued query parameters (`filter`, `sort`) travel as JSON text and array-valued ones repeat as `name[]=value`. - The MCP-only `_meta` field (usage analytics) never reaches the backend and is not part of this contract. version: '1.0' contact: name: GetSales url: https://getsales.io email: support@getsales.io license: name: Proprietary url: https://getsales.io/terms servers: - url: https://beta.getsales.io/playtables/v1 description: >- Production (the gateway path on the beta ring; the origin is provisioned per DEPLOY_MAP.md) security: - BearerJwt: [] TeamSid: [] tags: - name: activities description: >- Registry package `mcp.playtables/activities`, served on MCP mount `playtables.journeys`. - name: activity_objects description: >- Registry package `mcp.playtables/activity_objects`, served on MCP mount `playtables.people`. - name: companies description: >- Registry package `mcp.playtables/companies`, served on MCP mount `playtables.people`. - name: credit_ledger_entries description: >- Registry package `mcp.playtables/credit_ledger_entries`, served on MCP mount `id.billing`. - name: data_source_items description: >- Registry package `mcp.playtables/data_source_items`, served on MCP mount `playtables.sources`. - name: data_sources description: >- Registry package `mcp.playtables/data_sources`, served on MCP mount `playtables.sources`. - name: notes description: >- Registry package `mcp.playtables/notes`, served on MCP mount `playtables.pipeline`. - name: people description: >- Registry package `mcp.playtables/people`, served on MCP mount `playtables.people`. - name: pipeline_stages description: >- Registry package `mcp.playtables/pipeline_stages`, served on MCP mount `playtables.pipeline`. - name: plays description: >- Registry package `mcp.playtables/plays`, served on MCP mount `playtables.pipeline`. - name: playtable_field_values description: >- Registry package `mcp.playtables/playtable_field_values`, served on MCP mount `playtables.columns`. - name: playtable_fields description: >- Registry package `mcp.playtables/playtable_fields`, served on MCP mount `playtables.columns`. - name: playtable_runs description: >- Registry package `mcp.playtables/playtable_runs`, served on MCP mount `playtables.columns`. - name: playtable_views description: >- Registry package `mcp.playtables/playtable_views`, served on MCP mount `playtables.tables`. - name: playtables description: >- Registry package `mcp.playtables/playtables`, served on MCP mount `playtables.tables`. - name: result_pages description: >- Registry package `mcp.playtables/result_pages`, served on MCP mount `playtables.tables`. - name: sender_profiles description: >- Registry package `mcp.playtables/sender_profiles`, served on MCP mount `playtables.sources`. - name: stoplist_entries description: >- Registry package `mcp.playtables/stoplist_entries`, served on MCP mount `playtables.stoplist`. - name: tags description: >- Registry package `mcp.playtables/tags`, served on MCP mount `playtables.pipeline`. - name: workflow_attachments description: >- Registry package `mcp.playtables/workflow_attachments`, served on MCP mount `playtables.workflows`. - name: workflow_records description: >- Registry package `mcp.playtables/workflow_records`, served on MCP mount `playtables.journeys`. - name: workflow_sources description: >- Registry package `mcp.playtables/workflow_sources`, served on MCP mount `playtables.workflows`. - name: workflow_tasks description: >- Registry package `mcp.playtables/workflow_tasks`, served on MCP mount `playtables.journeys`. - name: workflow_versions description: >- Registry package `mcp.playtables/workflow_versions`, served on MCP mount `playtables.workflows`. - name: workflows description: >- Registry package `mcp.playtables/workflows`, served on MCP mount `playtables.workflows`. paths: /api/playtable-fields/{sid}/estimate-semantic-index: post: tags: - playtable_fields summary: Estimate semantic index cost description: >- What switching Semantic search on (or to another embed model) would cost ONE existing column, in credits, before the save: the backfill now (cost_expected over cells_to_embed of cells_filled; text already embedded with the same model is free) and one new or edited value later, as a range (cost_per_value_min to cost_per_value_max: a later value is its own call and its length is unknown until it lands).
