API Reference: Rate Limits by Tier
Rate limits scale with your plan. These are request-count and throughput ceilings, not per-method pricing. A heavy call like eth_getLogs counts the same as a light call like eth_blockNumber toward your quota.
| Tier | Requests/day | Requests/month | Requests/sec |
|---|---|---|---|
| Free | 20,000 | 600,000 | 40 |
| Build | 60,000 | 1.8 million | 60 |
| Basic | 500,000 | 15 million | 180 |
| Advanced | 1,600,000 | 48 million | 220 |
| Enterprise | Custom | Custom | Custom |

A 429 response means you hit your current tier's ceiling. Back off and retry, instead of hammering the endpoint. Consider a move to the next tier if this happens under normal, not abusive, traffic. See Common Methods & Error Handling for the full error code table.
