Priced per language-minute. One request can be twenty languages of a ten-minute cut — two independent multipliers, so both move the price. ## OpenAPI ````yaml /openapi.json post /v1/text/localize openapi: 3.1.0 info: title: Sigmora API version: 1.0.0 description: >- The priced, versioned public API. Every call authenticates with a workspace API key (`Authorization: Bearer sk_live_…`), names the project it files its output under, and reports what it cost. `GET /v1/capabilities` answers what this deployment can serve right now and at what price; anything it reports as unavailable answers 503 `capability_unavailable` rather than 404. servers: - url: https://api.sigmora.org security: - bearerAuth: [] tags: - name: Meta description: What this deployment serves, what it costs, and what you have spent. - name: Projects description: The container every capability files its output under. - name: Jobs description: Where every asynchronous capability is collected, whatever produced it. - name: Text description: Scripts, research, articles, translation and question sets. - name: Video description: Narrated renders, footage edits, shorts and moment selection. - name: 3D description: Animated 3D renders from a description or a photograph. - name: Image description: Thumbnails, sized for the platform they are posted to. - name: Audio description: Generated music. - name: Themes description: The canonical content taxonomy, and the niche profiles built on it. - name: Signals description: Evidence-backed trends and scored viral content. - name: Discovery description: Compiled watch plans, their runs, and source freshness. - name: Autopilot description: The durable trend-to-distribution workflow and its checkpoints. - name: Campaigns description: Distribution records shared by the API, the dashboard and autopilot. - name: Channels description: The destinations content is made for. - name: Products description: What a campaign promotes. paths: /v1/text/localize: post: tags: - Text summary: Translate and caption description: >- Translate a transcript into many languages with cue-accurate captions, and optionally dubbed audio.
