Celestia Rate Limits

Celestia publishes concrete RPC rate-limit numbers, which is unusual for a self-hosted protocol API — but they are DEFAULTS FOR A LIMITER THAT SHIPS DISABLED, configured by whoever runs the node, not enforced by a vendor. A consumer calling someone else's public RPC endpoint cannot know what limit applies to them, and there is no header that tells them. Recorded here as published defaults with that caveat attached.

Celestia Rate Limits is the machine-readable rate-limit profile for Celestia on the APIs.io network, in the API Commons Rate Limits shape.

It captures 4 rate-limit definitions.

Tagged areas include Blockchain, Data Availability, Web3, Infrastructure, and Open Source.

Limits

RequestsPerSec per-ip
· per 1s
100/1s
Sustained per-IP request rate. `Enabled = false` by default, so an out-of-the-box node enforces nothing.
CacheSize per-ip
8192
Caps how many distinct client IPs the limiter tracks, not a request rate.
max_request_body per-request
16
Hard server cap since v0.31.3. Not in config.toml and not adjustable. Larger requests are rejected.
max_concurrent_connections per-server
500
