A `queued` run ends `cancelled` at once and charges nothing; a `processing` run answers `cancelling` and stops at its next page, charging only the leads already delivered. A repeat answers the same; a finished run answers `already-terminal`. Nothing is fetched or billed after the answer beyond rows already delivered. #### Billing Free — this endpoint does not consume points. ## OpenAPI ````yaml /openapi.json post /api/v1/lead-search/runs/{runId}/cancel openapi: 3.1.0 info: title: Loice API version: v1 description: >- The Loice API finds and verifies professional contact data. Every capability is exposed here, key-authenticated and rate-limited; the web app is a client of the same platform. **Authentication** — pass your workspace API key on every request (except the API description) as `Authorization: Bearer loice_sk_…`. Keys are created under Settings → API Keys. **Billing** — operations are billed in points against your workspace balance. Each operation below states when the charge applies. The current cost of every operation is shown in the app under [Settings → Billing](https://app.loice.ai/settings/account?tab=billing) and in the live API description, `GET /api/v1/openapi.json`. Calls that fail because of a system or provider error (timeouts, upstream failures, our defects) are not billed, and rate-limited calls are rejected before any billable work. Check headroom with `GET /api/v1/points`. Where an operation documents an `Idempotency-Key` header, send one to retry safely: a repeated request returns the original outcome and is not charged again. **Errors** — every non-200 response has the shape `{ "error": { "message": "…" } }`. Operations whose error responses document an `error.code` also return that machine-readable code beside the message; branch on the code, not the text. servers: - url: https://app.loice.ai security: [] paths: /api/v1/lead-search/runs/{runId}/cancel: post: summary: Cancel a lead-search run description: >- Stops a lead-search run (spec 044, the same contract as the web screen).
