Use /source-topics/preview to inspect the selected set first. Returns the id of the created run and the number of enqueued jobs. Every trigger creates a NEW run; extracts are serialized per project — a 409 is returned while another extraction run is in flight. Sources whose metadata was not cached at scrape time are skipped by the worker. ## OpenAPI ````yaml https://api.mentionlab.io/api/docs-json post /api/v1/source-topics/extract openapi: 3.0.0 info: title: MentionLab Public API v0.3.4-rc description: '' version: 0.3.4-rc contact: {} servers: - url: https://api.mentionlab.io security: [] tags: [] paths: /api/v1/source-topics/extract: post: tags: - Source Topics summary: Trigger topic extraction for the sources in scope description: >- Selects the top 1000 source pages (deduped per url + month, ranked by citation count) matching the standard analytics filters (date range, countries, languages, models, queries, tags) and enqueues their cached page metadata (title + description) for vectorization into the source-topics vector store.

Jobs are deduped at the queue level, so re-triggering with the same scope is idempotent. Sources whose page metadata was not cached are skipped by the worker and are not represented in this count beyond their enqueue. example: 248 required: - runId - enqueued ApiErrorResponse: type: object properties: statusCode: type: number description: HTTP status code of the error. example: 400 message: type: string description: >- Human-readable description of the error.
