+### External Match Rate Limits
+
+The rate limits for the external match endpoints are as follows: 
+- **Quote**: 100 requests per minute
+- **Assemble**: 5 _unsettled_ bundles per minute. That is, if an assembled bundle is submitted on-chain, the rate limiter will reset. 
+If an assembled match is not settled on-chain, the rate limiter will remove one token from the per-minute allowance.
