API Reference
Introduction
The Relativity6 API platform exposes REST endpoints for business risk assessment and industry classification. All endpoints require an API key and return JSON.
Authentication
Include your API key in the x-api-key header on every request. Modern keys use the format r6-<keyId>.<secret>.
Keys are scoped to your organization. Quotas apply per organization across all keys.
Errors
Errors use conventional HTTP status codes with a JSON body:
- 400 — Invalid request body or parameters
- 401 — Missing or invalid API key
- 403 — Not entitled to the endpoint or resource
- 429 — Quota or rate limit exceeded
- 5xx — Server error
