It's 0 without an active plan. Works with any key; admin keys can also see plans and billing with `GET /api/v1/billing`. **Free.** This doesn't use any contacts from your plan. ## OpenAPI ````yaml /api-reference/openapi.json get /api/v1/usage openapi: 3.1.0 info: title: Intent Leads API version: '1.0' description: >- The Intent Leads API finds B2B people actively researching the topics you sell into, and exports them with contact details into your own tools. **Authentication.** Send an API key as a bearer token: `Authorization: Bearer il_live_…`. Keys belong to one organization. Standard keys work with everything except billing, team and key management, which need an admin key. **What costs contacts.** Only `POST /api/v1/exports` with `"dry_run": false` uses contacts from your plan. Quotes, counts, checks, samples and re-downloads are free. **Errors.** Every error is JSON: `{"error": "code", "message": "Plain-English explanation"}`. Codes are stable; messages may change. **Conventions.** JSON by default. Dates are `YYYY-MM-DD` and timestamps ISO 8601, all in UTC. Lane codes (`L1`) are case-insensitive. servers: - url: https://intentleads.si security: - bearerAuth: [] tags: - name: Exports description: Quote (free) and buy new people from your lanes, then download them. - name: Leads description: Pull and re-download the leads you've exported, and list deliveries. - name: Lanes description: >- Create, inspect and tune lanes: keywords plus the companies and roles you want. - name: Keywords description: Add and remove a lane's keywords; each one is approved as its own topic. - name: Checks description: >- Free lane checks that size every filter step over 14 days, plus quick topic signals. - name: Company list description: >- The target-company list your lanes can narrow to or use instead of industries. - name: Suppressions description: People you exported who later asked to be removed. - name: Usage description: Contacts used and left this billing period. - name: Billing description: Plan, invoices and plan changes.
