# Short-Sale Locate and SSR Checker

`POST /v1/tools/compute_short_sale_locate_ssr_checker`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/compute_short_sale_locate_ssr_checker`
- Auth: none declared

Deterministic locate-documentation and SSR-flag classification over caller-declared synthetic inputs. locate_satisfied follows the declared on-list flag under a declared source and date; ssr_restriction passes the declared SSR price-test flag through verbatim (the price test itself belongs to the caller's feeds); overall resolves to LOCATE_MISSING, SSR_RESTRICTED, or LOCATE_DOCUMENTED. Pairs with T372 (buy-in scope classifier) when no locate is documented. No borrow lists, no SSR tapes, no cutoff feeds, no registers, no network, no clock.

**Tool URL:** https://ainumbers.co/tools/671-short-sale-locate-ssr-checker.html
**AP2/Policy Mandate export:** yes

## Request body

  - `locate` object, required: declared locate documentation: source, list_date (YYYY-MM-DD), on_list
  - `ssr_active` boolean, required: declared pass-through of the caller price-test flag

## Response `200`

Successful tool execution result

- object
  - `locate_satisfied` boolean, nullable: True when the declared locate lists the symbol; null on the fail-closed path.
  - `ssr_restriction` boolean, nullable: Verbatim pass-through of the declared ssr_active flag; null on the fail-closed path.
  - `note` string: Deterministic note recording the declared inputs, or the fail-closed reasons naming each rejected input.
  - `overall` string, nullable: LOCATE_MISSING, SSR_RESTRICTED, or LOCATE_DOCUMENTED; null on the fail-closed path.
