description: >-
  IPinfo enforces rate limits per access token, not per IP. Limits are
  expressed as a monthly request quota on the Lookup endpoints (Core / Plus
  / Max / Enterprise) — the quota size is selected at sign-up via a slider
  (150k–5M / month) and overages bill at a per-1k rate. The free Lite tier
  has no daily, hourly, or per-second throttling, and paid tiers explicitly
  publish 'no concurrent request limits, no per-second throttling.' The
  Summarize IPs and Map IPs tools enforce a separate 5-uses-per-day limit
  irrespective of plan. The Batch endpoint allows bulk enrichment within
  the monthly quota.

policies:
  - name: Token-scoped limits
    description: All rate limits are enforced against the access token, not the source IP. Multiple deployments sharing one token share the quota.

  - name: Soft monthly quota with metered overages
    description: When the included monthly request count is exceeded, requests continue to succeed but are billed at the per-1k overage rate for the plan. Configurable alerts (e.g. 80% / 100% of quota) can be set in the dashboard.

  - name: 429 on tool throttling
    description: The /tools/summarize-ips and /tools/map endpoints return HTTP 429 with a message directing the caller to use the Lite API for higher-volume needs.

  - name: 403 on auth failure or quota lockout
    description: Returns HTTP 403 when the token is missing, invalid, or has been suspended for billing or policy reasons.

  - name: Three authentication methods
    description: Tokens can be presented via HTTP Basic Auth (token as username, empty password), Bearer header (Authorization Bearer), or query parameter (?token=...).

  - name: Database product bypasses limits
    description: Customers on the downloadable IPinfo Database product perform lookups locally with no API rate-limit applicability.
