V2 intentionally excludes saved company lists, list-based exports, and filtering searches by saved-list IDs. These features remain available in V1 and are not planned for V2. ## Authentication All API requests require a Bearer token passed in the `Authorization` header: ``` Authorization: Bearer YOUR_API_TOKEN ``` You can generate API tokens from your [dashboard](https://companyenrich.com/dashboard). ## Credits Most API calls consume credits. The credit cost for each endpoint is documented in its description. You can check your remaining credit balance using the User endpoint. ## Rate Limiting The global API limiter allows **500 requests per minute** per IP address. Authenticated API routes also use a per-user route limiter based on plan capabilities. Supplementary lookup endpoints (such as keyword/technology/industry autocompletes) use a separate per-user route-level bucket. termsOfService: https://companyenrich.com/terms-and-conditions contact: url: https://companyenrich.com/ email: support@companyenrich.com version: 2.0.0 servers: - url: https://api.companyenrich.com security: - Bearer: [] tags: - name: Company / Enrichment description: >- Enrich company data by domain, properties, or in batch.
