name: Crawl Census authentication
schemes:
- type: http
  scheme: bearer
  header: Authorization
  description: Existing accounts hold an API key. Send it as a bearer token on every request. There is no query-string form, so keys do not end up in logs and referrers.
  key_prefix_example: cc_live_
  scope: A key is scoped to one account. Rotating a key from the dashboard invalidates the previous one immediately.
  issuance: New keys are not being issued; the tiers that came with one were withdrawn.
- type: none
  description: Every read endpoint works unauthenticated (240 requests per hour per IP per the API page). POST /api/v1/scan and POST /api/v1/preflight also work without a key.
note: No OAuth, no scopes. The API page example key is "cc_live_9f2a7c41d8b34e6f" (documentation sample, recorded only as the cc_live_ prefix).
