Nostr Rate Limits

Scaffolded rate limit definitions for the Nostr API surface. Captures per-tier quotas, burst behavior, response signaling, and recovery semantics. Defaults are scaffold values to be replaced with published provider limits.

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

It captures 2 rate-limit definitions, across the free and pro tiers, measuring requests_per_minute.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled, quotaExceeded, and serviceUnavailable.

Tagged areas include Nostr, Decentralized Social, Open Protocol, Relays, and WebSocket.
