Public XOXNO endpoints are keyless. Gated features such as Relayer V3 require approval. Per-IP rate limits apply by default, and enterprise plans can provide custom limits and dedicated capacity.

​
WebSocket limits

The Relayer WebSocket at wss://relayer.xoxno.com/ws enforces the following connection-level constraints: Exceeding 64 control messages in a 5-second window closes the connection. See connection limits for reconnection strategy.

​
REST rate limits

​
Relayer API

The Relayer REST API at https://relayer.xoxno.com applies the following default rate limits:

​
Aggregator API

The DEX Aggregator at https://swap.xoxno.com applies these limits: Rate-limited responses return HTTP 429 with a Retry-After header. Every response includes X-RateLimit-Remaining so your client can self-throttle.

​
Enterprise plans

Enterprise plans can provide higher throughput, dedicated connections, and SLA terms:
  • Custom WebSocket topic subscription caps
  • Dedicated connection pools with reserved capacity
  • Priority transaction broadcasting
  • Custom rate limits and direct engineering support
