name: Cosmos API Rate Limits
description: >-
  The Cosmos SDK itself imposes no built-in rate limits on the LCD REST API
  server. Rate limiting is entirely dependent on deployment: self-hosted nodes
  have no limits by default; community public endpoints apply informal or
  infrastructure-level throttling; third-party commercial providers impose
  plan-based rate limits. The CometBFT RPC server supports a max_open_connections
  setting (default: 900) but no per-IP rate limiting out of the box.

rateLimits:

  - plan: Self-Hosted
    description: >-
      No rate limits enforced by the Cosmos SDK LCD server. Operators may add
      reverse-proxy-level rate limiting (e.g., nginx, Caddy) independently.
    requestsPerSecond: unlimited
    requestsPerMinute: unlimited
    requestsPerDay: unlimited
    burstLimit: unlimited
    concurrentConnections: unlimited
    notes: >-
      max_open_connections in config.toml applies to CometBFT RPC (default 900),
      not the LCD REST server.

  - plan: Community Public Endpoints
    description: >-
      Community-run public nodes may apply ad-hoc IP-based throttling. No
      documented limits exist; treat as best-effort with implicit low thresholds.
    requestsPerSecond: unknown
    requestsPerMinute: unknown
    requestsPerDay: unknown
    burstLimit: unknown
    concurrentConnections: unknown
    notes: >-
      Not intended for production use. Abusive usage may result in IP bans.

  - plan: Third-Party Node Provider (QuickNode Example)
    description: >-
      Third-party node providers impose tiered rate limits based on subscription
      plan. QuickNode, for example, measures usage in credits and enforces
      per-second and per-month request caps.
    requestsPerSecond: varies
    requestsPerMinute: varies
    requestsPerDay: varies
    burstLimit: varies
    concurrentConnections: varies
    notes: >-
      Consult your specific provider's plan documentation. Examples include
      QuickNode (https://www.quicknode.com/pricing), Blockdaemon, All That Node,
      and Cosmostation.
